NCT03061344

Brief Summary

Study Objectives The current definitive treatment options for urethral stricture disease include endoscopic urethrotomy known as Direct Vision Internal Urethrotomy (DVIU) or open reconstruction known as urethroplasty (1-6). The purpose of this study is to determine feasibility of endoscopic-only repair of urethral stricture or bladder neck contracture using a combination of existing surgical techniques of internal urethrotomy (or bladder neck incision) augmented by buccal mucosal graft.

Outcome Measures

Primary Outcomes (1)

  • Voiding Surgical Outcomes: Stricture Recurrence

    The ultimate outcome of this procedure is number of patients successfully treated without need for re-intervention (such as need for urethral dilation, endoscopic manipulation or open reconstruction). Recurrence of stricture will be reported as number of events. To detect stricture recurrence, patients will be monitored with: peak urine flow (milliliters per second) and post-void residuals (milliliters) and will be assessed post- operatively at every visit up to three years Flexible cystoscopy will be offered to patients at one year follow up or at any time point if there is suspicion of stricture recurrence based on patients complaints (reported as number of recurrences).

    3 years

Secondary Outcomes (3)

  • Immediate Perioperative Outcomes

    Day of surgery

  • Short-term Postoperative Outcomes

    Up to 90 days

  • Patient Satisfaction

    Post-operative up to 3 years follow up
