Transperineal bulbo‐prostatic anastomosis for posterior urethral stricture associated with false passage: a single‐centre experience

Abstract

• To evaluate the management of traumatic posterior urethral stricture associated with false passage, as this remains a challenge for urologists. • From January 2000 to February 2010, 19 patients (mean (range) age 34 [25-52] years) with traumatic posterior urethral obliteration associated with false passage were evaluated and treated at our centre. • All patients underwent perineal excision and primary anastomotic urethroplasty using cystoscopy by the suprapubic route to insert a guidewire into the original bladder neck, allowing exposure of the normal posterior urethra. • Patients underwent voiding cysto-urethrography 1 month after the procedure. When symptoms of decreased force of stream were present and uroflowmetry was <15 mL/s, urethrography and urethroscopy were repeated. • Clinical outcome was considered a failure when any postoperative instrumentation was needed, including dilatation. • The mean (range) follow-up was 12 (9-14) months. The overall success rate was 84%. • Three patients (16%) with persistent voiding difficulty developed a short anastomotic stricture 1-3 months after surgery. • The mean maximum urinary flow rate after surgery was 20.01 mL/s and no patient had urinary incontinence. • The preoperative use of flexible cystoscopy via the suprapubic route represented a successful key point of urethroplasty for posterior urethral stricture associated with false passage.
