Staged pendulous-prostatic anastomotic urethroplasty followed by reconstruction of the anterior urethra: an effective treatment for long-segment bulbar and membranous urethral stricture.
OBJECTIVE
To describe a novel surgical technique for male long-segment urethral stricture after pelvic trauma using the intact and pedicled pendulous urethra to replace the bulbar and membranous urethra, followed by reconstruction of the anterior urethra.


METHODS
Two patients with long-segment post-traumatic bulbar and membranous urethral strictures with short left pendulous urethras who had undergone several failed previous surgeries were treated with staged pendulous-prostatic anastomotic urethroplasty followed by reconstruction of the anterior urethra. This procedure was divided into three stages. First-stage surgery was mobilization of the anterior urethra down to the coronary sulcus and then rerouted to the prostatic urethra followed by pendulous-prostatic anastomotic urethroplasty with transposition of the penis to the perineum. Second-stage surgery was transecting the anterior urethra at the revascularised coronary sulcus 6 mo later, followed by straightening of the penis and urethroperineostomy. Third-stage surgery was reconstruction of the anterior urethra 6 mo later.


RESULTS
Postoperatively, the two patients reported satisfactory voiding. For patient 1, retrograde urethrography showed that the urethra was patent, and that the mean maximal flow rate (MFR) was 18.4 ml/s with no postvoiding residual urine after the third-stage surgery and at 3-yr follow-up. For patient 2, a 22F urethral catheter could pass smoothly through the urethra, and the MFR was 19.5 ml/s with no postvoiding residual urine at 2-yr follow-up.


CONCLUSIONS
This procedure was an effective surgical option for men with complex long-segment post-traumatic bulbar and membranous urethral strictures, especially for those who had undergone failed previous surgical treatments.
