Abstract :

Objective: To present our experience with buccal mucosa urethroplastyfor reconstruction of long segment anterior urethral strictures by dorsal onlay technique. Patients and methods: Between January 2011 and Feuary 2014, 56 patients with long anterior urethral strictures were managed by dorsal onlay BMG urethroplasty. Follow up included uroflowmetry with an ultrasonographic estimate of residual volume at 3 months, 1 year and yearly thereafter or at onset of obstructive voiding symptoms. Retrograde urethrogram (RGU) was done at 6 months. Cystoscopy was done in selected patients. Successful outcome was defined as natural voiding after catheter removal and no need for subsequent instrumentation. Results: Mean age of the patients was 47.2 years. The mean AUA symptom score was 23.2. The mean preoperative maximum flow rate was 7.2 ml/sec with mean residual volume 89.2ml. The mean stricture length was 8.9cm and mean urethral lumen diameter 8.6 Fr. The mean operative time was 133 mins. Mean follow up period was 25 months. Three patients developed recurrent strictures of which two patients underwent VIU and one underwent redo BMG urethroplasty. The success rate was 94.64%. The mean post operative maximum flow rate was 27.5 ml/sec with mean residual volume of 24.7 ml. Conclusion: Dorsal buccal mucosal graft urethroplasty provides excellent results for long anterior urethral stricture
