Concomitant treatment of ureteral calculi and ipsilateral pelvic sciatic nerve schwannoma with transperitoneal laparoscopic approach: A case report

BACKGROUND Schwannomas are rare peripheral neural myelin sheath tumors that originate from Schwann cells.Of the different types of schwannomas,pelvic sciatic nerve schwannoma is extremely rare.Definite preoperative diagnosis of pelvic schwannomas is difficult,and surgical resection is the gold standard for its definite diagnosis and treatment.CASE SUMMARY We present a case of pelvic schwannoma arising from the sciatic nerve that was detected in a 40-year-old man who underwent computed tomography for intermittent right lower back pain caused exclusively by a right ureteral calculus.Subsequently,successful transperitoneal laparoscopic surgery was performed for the intact removal of the stone and en bloc resection of the schwannoma.The total operative time was 125 min,and the estimated blood loss was inconspicuous.The surgical procedure was uneventful.The patient was discharged on postoperative day 5 with the simultaneous removal of the urinary catheter.However,the patient presented with motor and sensory disorders of the right lower limb,caused by partial damage to the right sciatic nerve.No tumor recurrence was observed at the postoperative appointment.CONCLUSION Histopathological examination of the specimen confirmed the diagnosis of a schwannoma.Thus,laparoscopic surgery is safe and feasible for concomitant extirpation of pelvic schwannomas and other pelvic and abdominal diseases that require surgical treatment.

Clinical application of flexible ureteroscopic sheath with controllable intraluminal pressure in treating ureteral stones

Objective:The purpose of the study was to assess the clinical efficacy and safety of a combined perfusion suction platform with pressure feedback control function and an ureteroscopic suction sheath that can measure the ureteropelvic pressure in implementing lithotripsies.Methods:Fifty-two patients who underwent lithotripsy under intelligent monitoring of ureteral intraluminal pressure from June 2016 to January 2018 were retrospectively recruited.The inclusion standard was stone diameter>1.5 cm but<2.5 cm.After the 12/14 Fr suction sheath was placed,manometer interface and suction interface of the sheath were connected to the platform via the pressure sensor and suction tube,respectively.The ureteroscope was connected to the platform perfusion pump,and the crushed stones were aspirated out under negative pressure.Results:According to the location of the stone,21(40.4%)cases were classified as upper ureteral stones,19(36.5%)were midureteral stones,and 12(23.1%)were lower ureteral stones.Forty-seven patients underwent successful primary sheath placement and lithotripsy with a mean operative time of 34.5(standard deviation 18.3)min.Retrograde stone migration did not occur.There were eight patients with hematuria postoperatively.Serious complication was 1.9% with one case of ureteral perforation.Stone clearance was 95.7% at Day 1e2 postoperatively,and 100% at Day 30 postoperatively.Conclusion:Ureteroscopic lithotripsy with intelligent pressure control using our device improved the efficiency of the lithotripsy and rate of stone clearance.The safety of the operation can be ensured.It is worth popularization and application in clinical practice.

Extracorporeal shock-wave versus pneumatic ureteroscopic lithotripsy in treatment of lower ureteral calculi

Aim: To compare the efficacy and complications of extracorporeal shock-wave lithotripsy (SWL) and pneumatic ureteroscopic lithotripsy (URS) in the treatment of lower ureteral calculi. Methods: From August 1997 to June 1999, 210 patients with calculi in the distal third of the ureter were treated with SWL and the other 180 with URS. The stones were fragmented with either HB-ESWL-V lithotripter or JML-93 pneumatic lithotripter through Wolf 7.5～9.0 Fr ureteroscope. The outcome was assessed in terms of stone clearance rate, re-treatment rate and complication incidence. Results: The stone clearance rate was 78.1% with SWL and 93.3 % with URS (P<0.05). SWL had a re-treatment rate of 11.9 %, vs 2.2 % in the URS group (P<.05). URS caused ureteral perforation in 3.3% of patients, while it was 0 with SWL (P<0.05). The differences in the incidence of other complications such as infection and stricture between the two groups were insignificant. Conclusion: Though the selection of these two options depends on equipments available and the expertise of the operator, we recommend URS as the optimal treatment for distal ureteral calculi.

Summary: The effectiveness and safety of ureteroscopic holmium:YAG laser lithotripsy for managing ureteral calculi was evaluated. Ureteroscopic holmium:YAG laser lithotripsy was performed in 168 ureteral calculi (upper 27 cases, middle 33 cases and lower 108 cases). The results showed that the stone-free rate was 92.6 % in the upper ureteral calculi, 93.9 % in the middle ureteral calculi and 94.4 % in the lower ureteral calculi, respectively. The complication rate was 4.8 % (8 cases). It was suggested that ureteroscopic holmium:YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral calculi.

Role of Removing Stasis and Reducing Heat Formula in Clearance of Proximal Ureteral Calculi after Ureteroscopic Ho:YAG Laser Lithotripsy: A Prospective Randomized Study

Objective To prospectively evaluate the efficacy of Removing Stasis and Reducing Heat Formula in accelerating calculus clearance and improving lower urinary tract symptoms of patients with proximal ureteral calculi after ureteroscopic Ho:YAG laser lithotripsy. Methods A total of 138 patients with proximal ureteral calculi underwent ureteroscopic Ho:YAG laser lithotripsy by a single endocrinologist. Stone size varied from 10 to 15 mm. After operation, the patients were randomly divided into three groups: the control group(group A), tamsulosin group(group B), and Removing Stasis and Reducing Heat Formula group(group C). The treatment lasted for 4 weeks or until stone clearance. The primary and secondary outcomes of the three groups at follow-up were assessed. Results Of the 131 patients available for follow-up, 44 cases were in the group A, 45 in the group B, and 42 in the group C, respectively. The stone free rate at 2 weeks in the groups B and C were significantly higher than that in the group A(95.56%, 97.62% vs. 79.55%; all P<0.05). The ureteral colic rate and mean time of fragment expulsion were significantly reduced in the groups B(4.44% and 7.86±4.99 days) and C(2.43% and 6.76±4.37 days) compared with the group A(22.73% and 11.54±9.89 days, all P<0.05). On the day of double-J ureteric stent removal, the group C differed significantly from the group A in the total International Prostate Symptom Score, irritative subscore, obstructive subscore, and quality of life score(all P<0.05). Conclusion Removing Stasis and Reducing Heat Formula in the medical expulsive therapy might be an effective modality for patients with calculus in the proximal uretera after ureteroscopic Ho:YAG laser lithotripsy.

Evaluation of Extracorporeal Shockwave Lithotripsy in the Management of Renal and Ureteral Calculi

Aim: To evaluate the efficacy of extracorporeal lithotripsy in the management of renal and ureteric calculi in a urology center in Douala, Cameroon. Materials and Methods: This is a retrospective study carried out over six years, between January 2014 and December 2020. All the patients were treated using a Direx Integra lithotripter, with the number of shockwaves ranging from 1200 to 3500, without anaesthesia and were discharged a few hours after the procedure on the same day. In a majority (63.75%) of the cases, the calculi were incidental findings. A Double-J stent was indicated in two patients and preceded extracorporeal lithotripsy because of renal colic and signs of urinary tract infection. Results: We recruited a total of 122 patients with a mean age of 42.19 ± 13.08. We had 65 (53.3%) males and all patients had at least one calculus confirmed by CT scan with a mean size of 13.84 ± 4.17 mm, 85 (69.7%) patients became completely stone-free after a maximum of four sessions of extracorporeal lithotripsy (ESWL). 21 (17.2%) patients had intermediate results, being asymptomatic and/or having less than three residual fragments that measured less than 4 mm. The failure rate was 13.9%, with 17 patients still having more than three fragments measuring more than 4 mm after 4 ESWL sessions. 1 (0.8%) had septic shock as a post ESWL complication while 6 (4.9%) benefitted from a complimentary medical and/or surgical treatment (double J stent placement). Conclusion: The management of renal and ureteral calculi through extracorporeal lithotripsy in adults seems to be particularly effective for renal calculi measuring less than 20 mm and ureteral calculi measuring less than 15 mm. Extracorporeal lithotripsy, which can be performed on an outpatient basis (and without anaesthesia) is associated with minimal complications, and remains the option of choice for most upper urinary tract calculi.

Dissolution of Ureteral Uric Acid Calculi with Local Litholytic Irrigation

This study was designed to evaluate the efficacy of local litholytic irrigation (LLI) in the treatment of ureteral uric acid calculi. Fourteen cases of ureteral uric acid calculi were diagnosed by abdominal plain radiography (KUB),retrograde urography,ultrasonography(B-mode ultrasound),spiral computerized tomography(CT) and blood biochemical examinations. A ureteral catheter was passed retrogradely across ureteral calculi by cystoscopy. LLI with tromethamine-E(THAM-E) was performed via the ureteral catheter after the improvement of renal function and general situation and the control of urinary tract infection under the condition of intravenous application of antibiotics. The irrigation rate varied from 1000 to 1500 ml per day. Retrograde pyelography demonstrated complete dissolution of all the stones,13 cases within 10 days and 1 within 12 days. Mild hematuria was observed in the majority of the cases and temporary aggravated lumbago in 1 case,with no other side effects. It is concluded that LLI is a practical and effective method in the treatment of ureteral uric acid calculi for its advantages of shorter duration,lower cost,less physical suffering and no severe complications.

Inverted Y ureteral duplication with an ectopic ureter and multiple urinary calculi:A case report

BACKGROUND In the clinical treatment of diseases related to ureteral duplication,it is very important to make a clear diagnosis before surgery because different types of ureteral duplication correspond to different treatment options.Inverted Y ureteral duplication with ectopic ureters and multiple urinary calculi is clinically rare.This case can help clinicians increase their understanding of this disease and gain some experience in its diagnosis and treatment.CASE SUMMARY A 36-year-old male who was previously healthy presented to the hospital with lumbar pain.Percussion of the right kidney area showed the patient had pain.Computed tomography scans revealed multiple urinary calculi in the right urinary system.Computed tomography urography revealed a duplicated ureteral malformation with an ectopic ureter.A transurethral ureteroscopic holmium laser lithotripsy was performed successfully.Intraoperative retrograde ureterography was performed,and the ectopic ureter was visible.We informed the family of the intraoperative findings and suggested laparoscopic ectopic ureterectomy for the ectopic ureteral stones.Unfortunately,the family temporarily refused laparoscopic surgery.The patient did not feel any discomfort after one year of followup.CONCLUSION Inverted Y ureteral duplication with an ectopic ureter and multiple urinary calculi is rare.Clinicians must be highly vigilant,make a correct diagnosis before surgery,determine the type of ureteral duplication and the distribution of urinary calculi,and then draw up a reasonable treatment plan to avoid unnecessary complications.

Changes of serum β2-MG, Cys C and urine mAlb levels in patients with ureteral calculi before and after extracorporeal shock wave lithotripsy and their clinical significance

Objective:To investigate the changes of serumβ2 microglobulin(β2-MG),cystatin C(CysC)and urine microalbumin(mAlb)levels in patients with ureteral calculi before and after extracorporeal shock wave lithotripsy and their clinical significance.Methods Sixty-eight patients with ureteral calculi admitted to the hospital between June 2018 and June 2019 were selected as the observation group.35 volunteers who received physical elimination in the hospital during the same period were selected as the control group.Levels ofβ2-MG,Cys C and urine mAlb in the observation group were compared before and after treatment,and compared with those in the control group.Changes in serumβ2-MG,Cys C and urine mAlb levels and renal function indicators[blood urea nitrogen(BUN),serum creatinine(SCr)]in patients with different prognosis in the observation group after treatment were analyzed.The value of serumβ2-MG,Cys C and urine mAlb levels in the diagnosis and treatment of ureteral calculi was analyzed with ROC curve.The correlations between serumβ2-MG,Cys C and urine mAlb levels and renal function indexes were analyzed.Results Serumβ2-MG,Cys C and urine mAlb levels in the observation group before treatment were significantly higher than those in the same group after treatment or those in the control group(P<0.05).Serumβ2-MG,Cys C and urine mAlb levels,BUN and SCr in patients with residual stones were significantly higher than those in patients without(P<0.05).ROC curve analysis showed that the sensitivity and the area under the curve of combined detection of serumβ2-MG,Cys C and urine mAlb levels for evaluating the curative effect of extracorporeal shock wave lithotripsy on ureteral calculi were significantly higher/larger than those of single detection of the three(P<0.05).Partial correlation analysis showed that serumβ2-MG,Cys C and urine mAlb levels were positively correlated with BUN and SCr(P<0.05).Conclusion There are obvious changes of serumβ2-MG,Cys C and urine mAlb levels in patients with ureteral calculi before and after extracorporeal shock wave lithotripsy.The combined detection of the three indexes is helpful for the early diagnosis of ureteral calculi and the evaluation of renal function after lithotripsy.They can provide reference for protecting renal function in patients with ureteral calculi treated by extracorporeal shock wave lithotripsy.

Effectiveness of Medical Management in Spontaneous Expulsion of Lower Ureteral Calculi: A Prospective Study

Purpose: We evaluated the efficacy of combined drug therapy with alpha1-adrenergic antagonist tamsulosin and corticosteroid deflazocort for conservative expulsive therapy in patients with lower ureteric calculi. Materials and Methods: A total of 100 consecutive symptomatic patients with stones located in the Lower ureter were selected for the study who received oral tamsulosin 0.4 mg daily for 4 weeks and deflazocort 30 mg daily for 10 days and diclofenac IM/Oral on demand. Ultrasound follow-up and medical visits and X ray KUB were performed weekly for 4 weeks. Stone passage rate and time, pain episodes and endoscopical intervention were evaluated. Results: The stone expulsion rate was 87.8%. Mean stone size was 6.5 ± 2.14 mm. Mean expulsion time was 8 ± 1.84 days. Mean pain episodes were 1.50 ± 0.87 days. 11 patients needed intervention for stone retrieval. There was no statistically significant difference between the expulsion rates of right and left ureteral stones (P value = 0.31). Conclusions: Medical therapy with a combination of α1 adrenergic blocker and corticosteroid achieve good stone expulsion rates, lower pain episodes and should be considered in all patients with lower ureteral stones of size less than 10 mm who are not having any contraindications for medical therapy.

Effects of RIRS and Mini-PCNL on liver and kidney function,endocrine changes and trauma in patients with upper ureteral calculi

Objective: To investigate the effects of retrograde intrarenal surgery (RIRS) and Mini-percutaneous nephroscope lithoipsy (Mini-PCNL) on liver and kidney function, endocrine changes and trauma in patients with upper ureteral calculi. Methods: 100 patients with upper ureteral calculi admitted to our hospital from March 2016 to February 2018 were selected. They were randomly divided into observation group (RIRS group) and control group (Mini-PCNL group), with 50 cases in each group. The observation group was given RIRS, while the control group was given Mini-PCNL. At the same time, the expression levels of the liver function [including alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma transpeptidase (gamma-GT)], renal function [including urea nitrogen (BUN) and serum creatinine (Scr) levels], endocrine changes [including corticotropin (ACTH), cortisol (Cor), norepinephrine (NE)] and trauma related indexes [Including soluble vascular cell adhesion molecule-1 (sVCAM-1) and erythrocyte sedimentation rate (ESR)] were analyzed and compared between the two groups. Results: There was no significant difference in ALT, AST, γ-GT, BUN and Scr before and after operation between the two groups. The difference was not statistically significant (P>0.05). After operation, the levels of ACTH (27.37±3.29) pg/mL, Cor (150.09±18.47) ng/mL, NE (165.48±26.74) ug/L and sVCAM-1, (596.55±56.24) ng/mL in RIRS group were significantly lower than those in Mini-PCNL group ((38.42±4.33) pg/mL, (222.37±28.70) ng/mL, (287.26±25.29) ug/L and (820.62±72) mL)The differences were statistically significant (P<0.05). While the ESR level in RIRS group (8.29±0.63) mm/h was significantly higher than that in Mini-PCNL group (7.16±0.68) mm/h, and the differences were statistically significant (P<0.05). Conclusions: There is no significant difference in the liver and renal function between RIRS and Mini-PCNL in the treatment of upper ureteral calculi. RIRS can better improve the endocrine status of patients and reduce the damage of the body, which is a more ideal way of operation.

Comparison of the trauma between combined retrograde intrarenal surgery and mini-percutaneous nephrolithotomy for upper ureteral calculi

Objective: To compare the trauma between combined retrograde intrarenal surgery and mini-percutaneous nephrolithotomy for upper ureteral calculi. Methods: Patients with upper ureteral calculi who received lithotripsy in Pengzhou Hospital of Traditional Chinese Medicine between February 2015 and March 2017 were selected and randomly divided into two groups;RIRS group received combined retrograde intrarenal surgery and the Mini-PCNL group received mini-percutaneous nephrolithotomy. 3 d after surgery;the contents of liver and kidney function indexes and stress hormones in serum as well as the expression of CD4+T cell transcription factors in peripheral blood were measured. Results: Serum ALT;AST;γ-GT;BUN and Cr contents of RIRS group 3 d after surgery were not significantly different from those of Mini-PCNL group;and HO-1;ET-1;ACTH;Cor and YKL-40 contents in serum as well as RORγt and T-bet mRNA expression in peripheral blood were significantly lower than those of Mini-PCNL group while Gata-3 and Foxp3 mRNA expression in peripheral blood were higher than those of Mini-PCNL group. Conclusion: Combined retrograde intrarenal surgery for upper ureteral calculi activates less stress response and inflammatory response than mini-percutaneous nephrolithotomy.

Percutaneous nephrolithotomy vs laparoscopic ureterolithotomy for large upper ureteral stone: A review article

To investigate the best treatment option for large upper ureteral stone,percutaneous nephrolithotomy or laparoscopic ureterolithotomy.We searched three key word of upper ureteral stone,laparoscopic ureterolithotomy,percutaneous nephrolithotomy in PubM ed,Scopus and Ebsco.We found approximately twenty suitable articles about this subject since January 1980 until January2014.All articles studies and reviewed meticulously and brief review of these articles was written and some Ideas of experts was added.In many studies,it is suggested that success rate and complications of laparoscopic ureterolithotomy and percutaneous nephrolithotomy are the same,but percutaneous nephrolithotomy has less hospital stay time,duration of surgery and it is more cost effective.Overall it seems that percutaneous nephrolithotomy for treatment of upper ureteral stones is preferable rather than laparoscopic

Rigid ureteroscopy in prone split-leg position for fragmentation of female ureteral stones:A case report

BACKGROUND Ureteroscopy is widely used in the treatment of ureteral stones due to the increased morbidity of turolithiasis.This is the first report of a case of ureteral calculi treated with rigid ureteroscopy in the modified prone split-leg position.CASE SUMMARY A 62-year-old Asian woman was diagnosed with a ureteral stone and underwent extracorporeal shock wave lithotripsy twice.However,the abdominal computer tomography scan showed persistent calculi on the right lower ureter.Her left hip movement was limited because of a left femoral neck fracture that did not receive proper treatment in a timely manner.She was unable to undergo surgery in the lithotomy position and refused to accept flexible ureteroscopy treatment.Therefore,rigid ureteroscopy was performed with her in the modified prone split-leg position.The ureteral calculi were successfully fragmented.CONCLUSION It is feasible to treat lower ureteral calculi in women in the prone split-leg position with the implementation of rigid ureteroscopy.

Transperitoneal Laparoscopic Ureterotomy: A Mini-Invasive Option for Ureteral Stones

Background and Objective: Laparoscopy can be an alternative modality in the management of ureteral stones. We herein present our experience with laparoscopic ureterolithotomy although most ureteral stones are managed using endourologic techniques, open surgery, or shockwave lithotripsy. Materials and Methods: This retrospective study was performed from January 2014 to December 2019 on 20 patients with ureteral stones who were treated using transperitoneal laparoscopic access. We collected data on patients’ ages, genders, clinical profiles, relevant medical history, sizes of the calculi, localisation of the calculi as confirmed by imaging, and outcome of lithotripsy. Continuous data were presented as mean values and standard deviations (for normally distributed data) and medians with interquartile ranges (for skewed data). Categorical data were presented as frequencies and percentages. Results: We included 20 patients (13 males and 7 females) with a mean age of 40.40 ± 13.25 years. The mean stone size was 18.5 ± 3.05 mm and all procedures were completed laparoscopically. The mean operative time was 96 ± 22.34 minutes. The mean estimated blood loss was less than 150 ml, and none of the patients received a blood transfusion. There was no intraoperative complication or postoperative complications, except for leakage of urine in the suture area. The mean hospital stay was 2.05 ± 0.69 days and the double J stent was removed after an average of 20 days post-operatively. The stone-free rate was 100% and after a mean follow-up period of 3 months, there was no stone recurrence. Conclusion: Laparoscopic ureterolithotomy is an effective and safe technique in the management of ureteric stones. The benefits of this technique include minimal postoperative morbidity, short postoperative hospitalization, a short convalescence period, and remarkable cosmetic results.
