Analysis of the urethral stricture score and patient-related factors as predictors of outcomes following oral mucosal graft urethroplasty

Objective:The complexity of urethral strictures can predict outcomes following urethroplasty.The previously described urethral stricture score(U score)considered only stricture-related factors to grade the complexity of urethral strictures and to predict recurrence post urethroplasty,but not considered patient-related factors for the same.We aimed to study the correlation of both of these factors to the outcomes of oral mucosal graft urethroplasty.Methods:We retrospectively reviewed data of 101 patients who underwent oral mucosal graft urethroplasty in our institute with a minimum follow-up of 6 months.Baseline patient characteristics and stricture-related parameters were noted.The U score was calculated for all patients which consisted of the length,location,number,and etiology of stricture.Univariate and multivariate Cox proportional hazard regression models were used to determine significant risk factors of recurrence.Results:The mean follow-up of patients was 15 months.Recurrence was seen in 28 patients and the mean time for detection of recurrence was 8 months of follow-up.The Charlson Comorbidity Index,history of previous intervention,length of strictures,location of strictures,number of strictures,history of smoking,and etiology were independent predictors of recurrence following urethroplasty.Based on these parameters,we formulated the modified U score(MU score).The scores ranged from 0 to 6 and a score of>2 was found to be predictive of recurrence.On comparing receiver operating characteristic curves for both scores by the DeLong test,the MU score had larger area under the curve than the U score.Conclusion:The MU scoring system is the first of its kind attempt taking into consideration both patient-and stricture-related factors to predict recurrence following oral mucosal graft urethroplasty.

Understanding female urinary continence-lessons from complications of female urethral surgery

Dear Editor,We share our experience of two significant complications associated with female urethroplasty and their management in understanding the factors contributing to urinary continence.We have also tried to assess the different components of female urinary continence mechanism and the ways to combat the postoperative urinary continence while performing female urethral surgeries(Fig.1).Informed consent was taken from each of the patients before their evaluation and management.They were explained properly and informed consents were taken from them before the publication of this article.

First report of the histopathological effect of electrocautery using on the urethral taste rosea during glans penis injury by incision in rabbits

Objective:Currently,electrocautery devices have frequently been used in penile surgical procedures.We hypothesized that electrocautery using during penile surgical procedures may harm the taste rosea and the dorsal nerve of the penis or clitoris.Methods:Eighteen young age male New Zealand rabbits were studied:five in the control(Group I,n=5),five in the penile surgery without using electrocautery(sham group,Group II,n=5),eight in the monopolar cautery(study group,Group III,n=8)groups under general anesthesia.The animals were followed for 3 weeks and sacrificed.Penile tissue—pudendal nerve root complexes and dorsal root ganglion of sacral 3 level were examined using stereological methods.The results were compared statistically.Results:The live and degenerated taste bud-like structures and degenerated neuron densities of pudendal ganglia(mean±standard deviation,n/mm^(3))were estimated as 198±24/mm^(3),4±1/mm^(3),and 5±1/mm^(3) in Group I;8±3/mm^(3),174±21/mm^(3),and 24±7/mm^(3) in Group II;and 21±5/mm^(3),137±14/mm^(3),and 95±12/mm^(3) in Group III,respectively.Neurodegeneration of taste buds and pudendal ganglia was significantly different between groups.Conclusion:Intact spinal cord and normal parasympathetic and thoracolumbar sympathetic networks are crucial for human sexual function.The present study indicates that the glans penis injury by using electrocautery may lead to pudendal ganglia degeneration.Iatrogenic damage to taste rosea and retrograde degeneration of the pudendal nerve may be the cause of sexual dysfunction responsible mechanism.

Etiology and management of urethral calculi:A systematic review of contemporary series

Objective:To conduct a systematic literature review on urethral calculi in a contemporary cohort describing etiology,investigation,and management patterns.Methods:A systematic search of MEDLINE and Cochrane Central Register of Controlled Trials(CENTRAL)databases was performed.Articles,including case reports and case series on urethral calculi published between January 2000 and December 2019,were included.Full-text manuscripts were reviewed for clinical parameters including symptomatology,etiology,medical history,investigations,treatment,and outcomes.Data were collated and analyzed with univariate methods.Results:Seventy-four publications met inclusion criteria,reporting on 95 cases.Voiding symptoms(41.1%),pain(40.0%),and acute urinary retention(32.6%)were common presenting features.Urethral calculi were most often initially investigated using plain X-ray(63.2%),with almost all radio-opaque(98.3%).Urethral calculi were frequently associated with coexistent bladder or upper urinary tract calculi(16.8%)and underlying urethral pathology(53.7%)including diverticulum(33.7%)or stricture(13.7%).Urethral calculi were most commonly managed with external urethrolithotomy(31.6%),retrograde manipulation(22.1%),and endoscopic in situ lithotripsy(17.9%).Conclusion:This unique systematic review of urethral calculi provided a summary of clinical features and treatment trends with a suggested treatment algorithm.Management in contemporary urological practice should be according to calculus size,shape,anatomical location,and presence of urethral pathology.

Long-term outcomes of urethral balloon dilation for anterior urethral stricture: A prospective cohort study

Objective:To prospectively follow up a cohort of anterior urethral stricture disease patients managed with balloon dilation(BD)for 3 years to evaluate the long-term outcomes and to study factors that contribute to recurrence.Methods:This study included men who had urethral BD for significant anterior urethral stricture disease between January 2017 and March 2019.Data about the patient age,stricture characteristics,and recurrence date were recorded,along with information on postoperative indwelling catheter use and operative complications.Furthermore,information about the self-calibration procedure was collected and where available,free flow(FF)measurements during the follow-up period were recorded and analyzed.Success was defined as a lack of symptoms and acceptable FF rates(maximum flow rate>12 mL/s).Results:The final analysis was conducted on 187 patients.The mean follow-up period was 37 months.The long-term overall success rate at the end of our study was 66.8%.Our recurrence rate was 7.4%at 12 months,24.7%at 24 months,and reached 33.2%at the end of our study.The time to recurrence ranged from 91 days to 1635 days,with a mean of 670 days.The stricture-free survival was significantly shorter with lengthy peno-bulbar(p=0.031)and multiple strictures(p=0.015),and in the group of patients who were not committed to self-calibration protocol(p<0.011).However,post-procedural self-calibration was the most important factor that may have decreased the incidence of recurrence(odds ratioZ5.85).Adjuvant self-calibration after BD not only reduced the recurrence rate from 85.4%in the non-self-calibration group to 15.1%in the self-calibration one(p<0.001),but also improved the overall stricture-free survival and FF parameters.

Prospective randomized study correlating intra-operative urethral mucosal injury with early period after transurethral resection of the prostate stricture urethra: A novel concept

Objective:To investigate the incidence of urethral stricture during the early period after transurethral resection of the prostate(TURP)and correlate its incidence with intra-operative urethral mucosal injury during TURP.Also to compare the other established risk factors affecting the development of urethral stricture among patients undergoing monopolar or bipolar TURP over a period of 6 months follow-up as the prospective randomized study.Methods:One hundred and fifty men older than 50 years with lower-urinary tract symptoms associated with benign prostatic hyperplasia were randomized to undergo either standard monopolar TURP with glycine as the irrigation fluid or bipolar TURP with normal saline as irrigant.The prostate size,operative time,intra-operative mucosal rupture,catheter time,catheter traction duration,uroflowmetry,and post-operative stricture rate were compared.Results:A total of 150 patients underwent TURP,including 74 patients undergoing monopolar TURP(one patient was excluded as his post-operative histopathological examination report was of adenocarcinoma prostate)and 75 patients undergoing bipolar-TURP,all of which were performed using a 26 Fr sheath resectoscope.The mean International Prostate Symptom Score and maximum urinary flow rate score at post-operative 3 months and 6 months were comparable between the groups.Out of 149 patients,nine patients(6.0%)developed urethral stricture.The severity of the injury(urethral mucosal injury)correlated with the likelihood of developing a subsequent complication(stricture urethra).Patients with stricture had significantly larger prostate volume than patients without stricture(65.0 mL vs.50.0 mL;p=0.030).Patients with stricture had longer operative time than patients without stricture(55.0 min vs.40.0 min;p=0.002).In both procedures,formation of post-operative stricture urethra was independently associated with intra-operative mucosal injury.Conclusion:Intra-operative recognition of urethral mucosal injury helps in prediction of stricture urethra formation in early post-operative period.

Investigation of risk factors in the development of recurrent urethral stricture after internal urethrotomy

BACKGROUND Urethral stricture is a condition that often develops with trauma and results in narrowing of the urethral lumen.Although endoscopic methods are mostly used in its treatment,it has high recurrence rates.Therefore,open urethroplasty is recommended after unsuccessful endoscopic treatments.AIM To investigate the risk factors associated with urethral stricture recurrence.METHODS The data of male patients who underwent internal urethrotomy for urethral stricture between January 2017 and January 2023 were retrospectively analyzed.Demographic data,comorbidities,preoperative haemogram,and biochemical values obtained from peripheral blood and operative data were recorded.Patients were divided into two groups in terms of recurrence development;recurrence and non-recurrence.Initially recorded data were compared between the two groups.RESULTS A total of 303 patients were included in the study.The mean age of the patients was 66.6±13.6 years.The mean duration of recurrence development was 9.63±9.84(min-max:1-39)months in the recurrence group.Recurrence did not occur in non-recurrence group throughout the follow-up period with an average time of 44.15±24.07(min-max:12-84)months.In the comparison of both groups,the presence of diabetes mellitus(DM),hypertension(HT),and multiple comorbidi-ties were significantly higher in the recurrence(+)group(P=0.038,P=0.012,P=0.013).Blood group,postoperative use of non-steroidal anti-inflammatory drugs,preoperative cystostomy,cause of stricture,iatrogenic cause of stricture,location and length of stricture,indwelling urinary cathater size and day of catheter removal did not differ between the two groups.No statistically significant difference was observed between the two groups in terms of age,uroflowmetric maximum flow rate value,hemo-gram parameters,aspartate aminotransferase(AST),alanine aminotransferase(ALT),fasting blood sugar,creati-nine,glomerular filtration rate,neutrophil-lymphocyte ratio,platelet-lymphocyte ratio,lymphocyte-monocyte ratio,monocyte-lymphocyte ratio and AST/ALT ratios.CONCLUSION In patients with urethral stricture recurrence,only the frequency of DM and HT was high,while inflammation marker levels and stricture-related parameters were similar between the groups.

Endoscopic Internal Urethrotomy in the Treatment of Male Urethral Stenosis in the Urology-Andrology Department of KARA Teaching Hospital (Togo)

Introduction: Endoscopic internal urethrotomy (EIU) is a method for stricture opening using transurethral incision by direct visualisation of the urethral channel, resulting in a widening of the urinary canal with the aim of improving the quality of bladder emptying. The aim of the study was to evaluate the indication and results of EIU in the treatment of stenosis of the male urethra in the Urology-Andrology Department of Kara Teaching Hospital. Methodology: This was a cross-sectional descriptive study with retrospective data collection in the Urology-Andrology department of Kara Teaching Hospital. It involved 21 records of patients with urethral stenosis treated by endoscopic internal urethrotomy (EIU) in the said department during the period from January 2021 to September 2023. The following variables were evaluated: age, circumstance of discovery, site, length, number, etiology of the urethral stenosis and evolution of the patients. Results: The mean age of the patients was 59.2 ± 11.7 years. Infectious etiology of stenosis was predominant with 10 patients (47.6%) followed by trauma with 5 cases (23.8%). The bulbar urethra was the most frequently observed site, with 11 cases (52.4%). The length was mostly less than 2 cm in 12 patients (57.1%). Stenosis was unique in 14 patients (66.7%). The mean postoperative follow-up time was 3.2 months. The result was immediately better in 11 patients (52.4%) and it was poor in 8 patients (38.1%) who required maintenance dilation sessions.

Management and Outcome of Urethral Strictures at Two Tertiary Health Facilities in Cameroon

Introduction and Objectives: Urethral stricture is a reduction in the caliber of the urethral lumen impeding the outflow of urine. It predominantly affects males. The disease burden is severe in our milieu where access to specialized care is limited. Our goal was therefore to assess the management and outcome of male urethral stricture at two tertiary hospitals in Douala, Cameroon. Materials and Methods: This was a hospital-based retrospective study of patients managed for urethral stricture over 5 years (January 1st, 2017 to December 31st, 2021) at the Douala General and Laquintinie Hospitals. Data on sociodemographic, clinical, paraclinical, and treatment options were extracted using pre-structured forms. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 28. Statistical significance was set at p-value Results: We exploited 130 medical records. The mean age of patients was 46.5 years. Dysuria and weak urine stream were the major presenting complaints (63.8% and 23.8% respectively). The etiology of urethral stricture was iatrogenic in 42.3% of cases. The strictures were mostly single (89.8%), and the bulbar urethra was most affected (46.9%). 28 patients had urinary tract infections and the most frequently isolated germ was E. coli in 29.6%. Direct visual internal urethrotomy (DVIU) was performed in 42.3% of cases. Surgery, especially excision and primary anastomosis (EPA) was done in 28.5% of cases. Major complications were wound infection, acute kidney injury (AKI), and urethrocutaneous fistulae affecting 3.1, 2.3, and 1.5% of cases respectively. The recurrence rate was 17% with a mortality rate of 0.08%. Conclusion: Urethral stricture is common in our adult male population. The cause is mainly iatrogenic and the bulbar urethra is most affected. Minimally invasive and open reconstruction are frequently used treatment options with significant recurrence rates in the long term.

Urethroplasty among Elderly Men, Surgical Techniques and Outcomes

Introduction: Urethroplasty remains the gold standard for the management of urethral stricture. However, the treatment of stricture disease in the elderly tends to be less invasive due to the presumption that they might not be able to stand long hours of surgery and might have higher rates of recurrence due to poor wound healing from microangiopathy. We present our experience with the outcomes of urethroplasty among elderly men seen at the Komfo Anokye Teaching Hospital from January 2012 to December 2021. Methods: This was a retrospective review of data captured in the urology database on all patients 65 years and above who underwent urethroplasty at the hospital over the study period. Data was obtained on patients’ demographics, stricture characteristics, urethroplasty technique, and outcome. A successful outcome was defined as peak flow rate > 15 mls/s, a patent urethra on retrograde urethrogram, patient satisfaction with urine stream, or restoration of the normal stream of urine with only one attempt at urethral calibration or internal urethrotomy postoperatively. Data was analyzed using PASW Statistics for Windows, Version 18.0. Results: Overall, 43 urethroplasties were done over the study period in elderly men. The age range was 65 to 87 years. The commonest aetiology was catheterization (62.79%) followed by urethritis (32.56%). Stricture length ranged from 0.5 cm to 16 cm with a mean of 3.93 cm. Most patients (60.46%) had bulbar urethral strictures. The repair methods employed were anastomotic urethroplasty (62.80%), fasciocutaneous flap (FCF) ventral onlay (13.95%), buccal mucosa graft (BMG) ventral onlay urethroplasty (4.65%), and staged urethroplasty (4.65%). Three of the patients (6.98%) had a combination of anastomotic and tissue transfer urethroplasty. The overall success rate was 88.37%. Complications included three surgical site infections, two urethral diverticula and one glans dehiscence. Conclusion: Elderly men tolerate urethroplasty well and the procedure should not be denied solely based on age.

Analysis of Culture and Drug Sensitivity Tests of Mycoplasmas for 387 Patients with Nongonococcal Urethritis (Cervicitis) in Chongqing

Objective: To investigate the prevalence of myco-plasma infections and the sensitivity to antibiotics among patients with nongonococcal urethritis or cer-vicitis (NGU) in Chongqing. Methods: 387 NGU cases with mycoplasma-positive results upon culture were analysed retrospectively. RESULTS: The majority of patients with mycoplasma infections were in the 20-40 year old age group. No significant difference was found between males and females. Ureaplasma urealyticum is the main pathogen of these NGU cases and no clear relationship between its concentration and pathogenic ability was noted. Drug sensitivity was tested against nine antibiotics; the sensitivity rates to josamycim, minocycline and doxycycline were 94.06%, 88.89% and 86.82% respectively, while the resistance rates to lincomycin, ofloxacin, azithromycin and roxthromycin were 74.94%, 42.12%, 41.60% and 40.31% in turn. Conclusions: Josamycin, minocycline and doxycycline could be used as the first choice to treat NGU with mycoplasma infections in Chongqing. It is important to select antibiotics for NGU treatment with mycoplasma infections based on the results of drug sensitivity tests.

AIDS-Associated Mycoplasmas Infections in Patients with Nongonococcal Urethritis and Mucopurulent Cervicitis

Background: The incidence of sexually transmittedHIV infections is rapidly increasing in China, and theprevalence of AIDS-associated mycoplasmas (includingMycoplasma genitalium, Mycoplasma penetrans, Myco-plasma pirum and Mycoplasma fermentans) infections isunknown in patients with sexually transmitted diseases.Objective: To investigate the prevalence of these 4species of AIDS-associated mycoplasmas infections inpatients with nongonococcal urethritis (NGU) andmucopurulent cervicitis (MPC).Methods: In 65 patients with NGU/MPC, detection ofM. genitalium, M. penetrans, M. pirum and M. fermentansin genital and pharyngeal specimens was performed byculture and nested polymerase chain reaction.Results: M. genitalium, M. penetrans, M. pirum and M.fermentans were identified in genital specimens from23.1% (15/65), 12.3% (8/65), 1.5% (1/65) and 0% ofpatients, respectively, and from pharyngeal samples in26.2% (17/65), 15.4% (10/65), 1.5% (1/65) and 0% ofpatients, respectively. M. genitalium was detected in bothgenital and pharyngeal samples in 10.8% (7/65) ofpatients, and M. penetrans in 4.6% (3/65) of patients. M.pirum was found in only 2 cases, and no M. fermentanswas discovered.Conclusions: This study suggests that M. genitaliumand M. penetrans infections are common in patients withNGU/MPC. M. genitalium and M. penetrans may be trans-mitted by genital-genital or oral-genital sex, and maycause urethritis and cervicitis.

Efficacy Study on Six Antibiotic Methods for Treating Non-Gonococcal Urethritis and Cervicitis

Objective： To analyze the efficacy of six antibiotic methods for treating non- gonococcal urethritis /cervicitis and the factors influencing efficacy. Methods： Retrospective analysis of 878 nongonococcal urethritis / cervicitis cases which received regular treatment and follow-up in our institute from 1st Jan. 2001 to 31st Aug. 2003. Results： The mean cure rate of six methods for Chlamydia trachamatis （Ct） was 57.116%. There were distinct differences among these methods for Ct treatment.The mean cure rate of six methods for Ureaplasma urealyticum （Uu） was 69.556% and there was no difference among these methods for Uu treatment. Coinfection with Ct and Uu dramatically reduced the elimination rate of these two pathogens. Conclusion： The effectiveness of treatment of these antibodies for non-gonococcal urethritis / cervicitis is not currently satisfactory. Importantly, there were many antibiotic-resistant Ct and Uu strains. The factors influencing antibiotic efficacy and mechanisms need further study.

Detection and Identification of Gonococci Resistance to Cephalosporin and Determination the Most Effective Empirical Treatment for Gonococcal Urethritis in Male Human in Egypt

Introduction: Gonorrhoeae and antimicrobial resistance AMR of gonococci is a major health problem today, because emerged resistance to last line empirical treatment for gonorrhoeae cephalosporins in many countries is predictable to be untreatable disease in near future. WHO GASP, WHO GLASS and WHO’s global action plan on AMR recommends to expand nationally and internationally to collect data to monitor AMR of gonococci for public health policies. Objective: Our aim is to detect resistance of gonococci to Cepha- losporins and determine the most effective empirical treatment for un-com- plicated gonococcal urethritis in males in Egypt. Methods: We depended in our methodology on selected gonococci from male urethral discharge specimens on Thyer Martien medium;collected 33 isolates during three years from 2017 to 2020;used antibiotics with MIC according to international standards and measuring IZD according to antimicrobial susceptibility testing reference ranges in international standards. Results: By statistical studies, resistance to cephalosporins was as follows: Cephradine 97%, Cefaclor 87.9%, Cefoxitin 97%, Ceftriaxone 90.9% and 42.4% to Cefepime, that shows hetero-genecity in resistance inside cephalosporin group;while resistance to Macrolides group represented by Azithromycin and Tetracyclins group represented by Doxycycline was as follows: Azithromycin 39.4%, Doxycycilne 27.3%;finally fluoroquinolones, the most effective group, resistance, was as: Levofloxacin 15.2%, Ciprofloxacin 15.2% and Ofloxacin 24.2%. Conclusion: The most effective empirical treatment for uncomplicated gonococcal urethritis in males in EGYPT is Fluoroquinolone;especially Levofloxacin ranks first susceptibility as 78.8% and 15.2% resistance followed by Ciprofloxacin susceptibility as 69.7% and 15.2% resistance, finally Ofloxacin susceptibility as 66.7% and 24.2% resistance;for Ceftriaxone not more recommended in EGYPT as empirical treatment for uncomplicated gonococcal urethritis, it is susceptibility as 6.1% and 90.9% resistance;in addition, we can use combination therapy of Fluoroquinolones with Azithromycin or Doxycycline, whose susceptibility is 30.3% for Azithromycin and 42.4% for Doxycycycline, while resistance is 39.4% for Azithromycin and 27.3% for Doxycycline. It is worth noting that only Cefepime in Cephalosporins group represents 42.4% susceptibility and 42.4% resistance;in addition to the Carbapenems group, it represents as 42.4% susceptibility for Imipenem and 45.5% resistance, then 42.2% susceptibility for Meropenem and 48.5% resistance, which can play role in combination therapy.

Management of urethral strictures and stenosis caused by the endo-urological treatment of benign prostatic hyperplasiad-a single-center experience

Objective:Urethral stricture disease after endo-urological treatment of benign prostatic hyperplasia(BPH)is a sparsely described complication.We describe management of five categories of these strictures in this retrospective observational case series.Methods:One hundred and twenty-one patients presenting with symptoms of bladder outflow obstruction after endo-urological intervention for BPH from February 2016 to March 2019 were evaluated.Among them,76 were eligible for this study and underwent reconstructive surgery.Preoperative and postoperative assessments were done with symptom scores,uroflowmetry,ultrasound for post-void residue,and urethrogram.Any intervention during follow-up was classed as a failure.The recurrence and 95%confidence interval for recurrence percentage were calculated.Results:The following five categories of patients were identified:Bulbo-membranous(33[43.4%]),navicular fossa(21[27.6%]),penile/peno-bulbar(8[10.5%]),bladder neck stenosis(6[7.9%]),and multiple locations(8[10.5%]).The average age was 69 years(range:60-84 years).Overall average symptom score,flow rate,and post-void residue changed from 21 to 7,6 mL/s to 19 mL/s,and 210 mL to 20 mL,respectively.The average follow-up was 34 months(range:12-58 months).Overall recurrence and complication rates were 10.5%and 9.2%,respectively.The recurrence in each category was seen in 3,1,2,1,and 1 patient,respectively.Overall 95% confidence interval for recurrence percentage was 4.66-19.69.Conclusion:Urethral stricture disease is a major long-term complication of endo-urological treatment of BPH.The bulbo-membranous strictures need continence preserving approach.Navicular fossa strictures require minimally invasive and cosmetic consideration.Peno-bulbar strictures require judicious use of grafts and flaps.Bladder neck stenosis in this cohort could be treated with endoscopic measures.Multiple locations need treatment based on their sites in single-stage as far as possible.

Detection of Trichomonas Vaginalis Infection in Male Non-gonococcal Urethritis Patients by InPouch TV Culture and Polymerase Chain Reaction

Objective: To study the prevalence of Trichomonas vaginalis (TV) infection in Chinese male patients with nongonococcalurethritis (NGU), to evaluate the sensitivity and specificity ofurine-based and urethral swab polymerase chain reaction(PCR) detection, to set up a method for non-invasive detectionof male TV infection. Method: One hundred and five male NGU patients wereselected from a Beijing STD clinic. Two urethral swabs wereobtained from each patient, one for the InPouch TV culturesystem and the other for PCR. In addition, one first void urinespecimen was collected for PCR detection. Culture wasconsidered the 'gold standard'. The sensitivity, specificity,positive predictive value (PPV) and negative predictive value(NPV) of the two PCR detections were compared to cultureresults. Results: The prevalence of urine-based PCR and urethralswab PCR detection was 3.81% (4/105) and 4.76% (5/105)respectively. Compared to culture, the sensitivity, specificity,PPV and NPV were 80%, 100%, 100% and 99% for urinbased PCR and 80%, 99%, 80% and 99% for urethral swab PCR. Conclusion: TV is one of the etiological agents in male NGU,with a 4.76% prevalence of infection in our study. The urine-based PCR detection has higher sensitivity and specificity andprovides a noninvasive method more feasible in practice.

Cases analysis of rational use of medicine (31) Nongonococcal urethritis(NGU)

Double-face urethroplasty in patients with obliterative bulbar strictures post-transurethral resection of the prostate mid-term outcomes in high-volume referral center

Objective Incidences of post-transurethral resection of the prostate(post-TURP)strictures are between 2.2%and 9.8%.Stricture commonly occurs within the first 6 months.Our objective was to assess the outcomes of patients with obliterative strictures post-TURP that underwent a double-face urethroplasty.Methods This is a single-center prospective study of 17 patients with obliterative proximal bulbar stricture post-TURP who underwent double-face graft urethroplasty by two surgeons between January 2014 and January 2020.We defined post-TURP obliterative strictures as those patients who presented with complete or almost complete obstruction of the urethral lumen and who have had a history of acute urine retention.We have excluded patients with bladder neck contracture.Primary outcome was treatment success,defined as the no need for further treatments.Secondary outcome was post-urethroplasty continent rate.Results Seventeen patients were included in the study with median age of 66(interquartile range 40-77)years;median time of follow-up was 24(interquartile range 12-84)months;median stricture length was 4(interquartile range 2-6)cm.Of the 17 patients,15(88.2%)were successful.All patients were continent after urethroplasty.Conclusion With mid-term follow-up,treatment of obliterative proximal bulbar strictures with double-face buccal mucosa graft is a safe and effective procedure.Obliterative proximal bulbar strictures merit double-face urethroplasty with high-rate success and functional outcomes.

Tunica albuginea versus buccal mucosa graft urethroplasty for anterior urethral stricture: A prospective randomised pilot study

Objective:The objective of the study was to compare the outcome of tunica albuginea urethroplasty(TAU)and buccal mucosa graft(BMG)urethroplasty for anterior urethral stricture.Methods:Thirty patients who met the inclusion criteria were randomised into two groups:TAU(Group A)and BMG urethroplasty(Group B).Surgical outcome was evaluated with pre-and post-operative work-up involving retrograde urethrogram,voiding cystourethrogram,uroflowmetry,and urethroscopy.Patients were followed up till 1 year.Results:Mean duration of surgery was statistically significant between two groups(p=0.0005).Maximum urine flow rate was comparable when compared between two groups(p=0.22)but statistically significant when compared pre-and post-operatively(p<0.001).At follow-up of 1 year,the successful outcomes were 80% in Group A and 87%in Group B.A total of five patients who had unsuccessful results required redo urethroplasty.Complications were minimal in both the groups.Conclusion:TAU provides outcomes equivalent to those of BMG urethroplasty.TAU has less operative time,easy to perform,and beneficial in patients with poor oral hygiene.

Severe Coital Accident: A Rare Case of Simultaneous Fracture of the Penis and a Complete Urethral Rupture at the University Hospital of Bouake

Cavernous body fracture is a rare urological emergency. Its association with complete rupture of the urethra remains exceptional. This is a report of simultaneous penile fracture and complete rupture of the urethra following a misstep in coitus. It is about a 41-year-old young adult, admitted to the surgical emergency department of the University Hospital of Bouaké on March 2, 2020 for penile pain associated with acute retention of urine. The clinical examination confirmed the diagnosis of a corpus cavernosa fracture associated with a ruptured urethra. The patient underwent cystostomy, right cavernoraphy and urethrorrhaphy. The postoperative follow-up was straightforward and the patient was discharged from the hospital on D3 postoperatively. The urethral catheter was removed on D21 postoperatively. With a follow-up of 1 year, the patient presents a good erection and does not report any voiding disorder.
