In our context, due to financial limitations, reconstructive urologists prefer to use the uroflowmetry in order to assess the micturition post-surgery. Therefore, the objective of the study was to assess the quality of micturition using the uroflowmetry after anastomotic urethroplasty. Methodology: We conducted an 11-year retrospective review (1<sup>st</sup> January 2006-31<sup>st</sup> December 2017) and a cross-sectional descriptive observational study for a period of 8 months (November 2017-June 2018) at the Urology and Andrology Department of the Yaounde Central Hospital (YCH) of patients who were diagnosed with urethral stenosis and underwent an anastomotic urethroplasty at the YCH. We excluded patients who had incomplete files, patients lost to follow-up and did not do pre-operative uroflowmetry. Quality of micturition was evaluated using a uroflowmetry. Data was analyzed using EPI info 7.0. Parametric variables were reported as means and standard deviations and percentages and counts were used to report categorical variables. Results: We had a sample of 60 patients. The mean age was 42 ± 5 years with extremes ranging from 20 to 76 years. Twenty-seven (27) patients, or 45%, had no post-operative complications, and those who did had a urinary tract infection (26.70%). In our series, we had 82% excellent results (patient satisfied with his urination with bell-shaped urinary stream and urinary flow greater than or equal to 15 ml/sec);15% good results (patient with moderate dysuria with average urinary stream and urinary flow between 10 and 14.9 ml/sec) and 3% poor results (severe dysuria with urinary flow less than 10 ml/sec, urinary retention or urinary incontinence). Based on these results we can say that the success rate in our series was 97%. 96.70% of patients were satisfied against 3.3% who were not. Conclusion: Anastomotic urethroplasty is the gold standard for the treatment of short urethral strictures. The results are good in the immediate and long term post-operative period. The use of the uroflowmetry as a screening tool for evaluating the quality of micturition after urethroplasty is effective.展开更多

Material and Method: We conducted a descriptive and analytical retrospective study based on the records of patients who underwent urethroplasty in the department, between February 2001 and September 2013. Results: Ninety-one (91) patients were enrolled. Urethroplasties prevalence was 0.83% of the surgical activity of the service. The mean age of patients was 39.83 years. Dysuria (30.77%) followed by pelvic trauma (28.57%) and urinary retentions (25.27%) was the main discovery mode. A periurethral coating was found in 32 patients. The infectious etiology accounted for 44% of cases. In 63% of cases, diagnostic was made by retrograde cystography. The penile urethra was the favorite seat of the UR in 70% of cases. The average length of the urethral stricture (US) was less than 1 cm in 41.17% of cases. The US was unique in more than half of the cases (58.33%). Anastomotic urethroplasty was the best surgical technique with 73.63% of patients. Postoperative morbidity involved 47 patients and was dominated by urinary infections (36 year old). The average duration of follow-up of operated patients was 29 months. After 6 months of follow-up, the best results were obtained with the termino-terminal urethroplasty technique with 62.5%. After a follow-up of 4 years, the success rate was 58.24%. The length of the stenosis and the allocation of gestures on the urethra were the two factors of failure. Conclusion: Stenosis is common in our regions. Treatment results are disappointing. Urethroplasty is the gold standard of surgical treatment and anastomotic urethroplasty gives better results.展开更多

A total of 23 patients with traumatic posterior urethral stricture were enrolled and then divided into two groups. In one group, 12 patients underwent non-transecting anastomotic urethroplasty. In the other group, 11 patients underwent conventional posterior urethra end-to-end anastomosis. The effect of operation was evaluated using the following parameters： the bleeding amount during operation, operation time, IIEF-5 scores after operation, maximum flow rate （Qmax）, and rating scale of quality of life （QoL）. The comparison between the conventional posterior urethra end-to-end anastomosis group and the non-transecting anastomotic urethroplasty group showed no significant difference with regard to average operation time. However, a significant difference was observed between the groups with regard to the bleeding amount during operation. The patients in the group of uon-transecting anastomotic urethroplasty urinated smoothly after the removal of catheter. Meanwhile, one patient from the group of conventional posterior urethra end-to-end anastomosis had difficulty urinating after the removal of catheter. Furthermore, significant differences in the operation time, bleeding amount during operation, IIEF-5 scores after operation, and rating scale of QoL were observed, whereas no significant difference was observed between urine flow rates of the two groups after operation. Overall, non-transecting anastomotic urethroplasty is effective for posterior urethra reconstruction, and it can reduce the occurrence rate of erectile dysfunction after operation.展开更多

Management is often surgical, with possible recurrences. What about this pathology in Kara, a semi-urban city? Objective: Assess the management of male urethral stricture in Kara. Patients and Methods: This was a descriptive study with retrospective data collection. The study took place in the urology department of the teaching hospital of Kara, from December 2020 to December 2022. All cases of male urethral stricture, surgically treated at the teaching hospital of Kara, were listed. The inclusion criteria were as follows: any patient who had been treated surgically for male urethral stricture in the urology department of the teaching Hospital of Kara. The operating theater register and hospital records were used to collect the data. The diagnosis of urethral stricture had been made with retrograde urethrogram. A total of 24 patients were treated for male urethral stricture during the study period. The following variables were studied: age, reason for consultation, location, length, and etiology of the stricture;the type of treatment received: optical internal urethrotomy, or anastomotic urethroplasty, and the results. The result was considered good if, after removal of the urethral catheter, the patient regained his micturition without the need for dilatation;the result was considered average if, after removal of the urethral catheter, the patient needed one or more dilatation sessions to regain urination;the result was considered poor if, after removal of the catheter, the patient did not regain good micturition despite the urethral dilatation sessions. Microsoft excel and epi info 7 software were used for data processing. Results: The average age of our patients was 43.7 years ± 10.18 with extremes ranging from 27 to 70 years. The most represented age groups were that of 40 to 50 years, with 37.5% of cases;and that of 30 to 40 years with 33.3% of cases. The patients had consulted for urine retention in 66.6% of cases;the location of urethral stricture was bulbar in 45.8% of cases. The most found etiology was infectious in 58.3% of cases. Among our patients, 58.3% had received optical internal urethrotomy as treatment, while 41.6% of our patients had received anastomotic urethroplasty as treatment. Postoperatively, after removal of the urinary catheter, 87.5% of patients had benefited from one or repeated dilatation. In terms of results, we had a good result in 20.8% of patients;the result was average in 45.8% of patients, and poor in 33.3% of patients. The average duration of follow-up was 14.3 +/- 7.2 months (3-27). Conclusion: Male urethral stricture mainly affects young adults in Kara. Surgical management is done by optical internal urethrotomy and/or anastomotic urethroplasty.展开更多
