[Modified urethral pull-through procedure for post-trauma posterior urethral stricture]

Abstract

Objective: To evaluate the effect of the modified urethral pull-through procedure in the surgical treatment of posterior urethral stricture or obliteration caused by trauma.

Methods: From January 2001 to June 2005, modified urethral pull-through procedures were performed in 36 patients with post-trauma posterior urethral stricture or obliteration, 25 of them with post-operation urethral stricture or obliteration after urethral realignment by traction and the other 11 treated by cystostomy at the time of initial injury. The length of the urethral stricture segment was 1.0-4.5 cm, mean 2.2 cm. The patients were aged from 17 to 59 years (mean 44.5 years).

Results: All the patients were followed up for at least 1 year. Success was achieved in 34 patients, among whom 25 had good voiding and no need of dilation, 6 were cured after 3 - 6 post-operative dilations, 3 required dilation every 2 or 3 months for over a year and 2 failed. No blood transfusion was needed during the operation, and no erectile dysfunction or incontinence occurred after it.

Conclusion: The modified urethral pull-through procedure is effective and simple in the surgical treatment of post-trauma posterior urethral stricture or obliteration, with few complications and no consequent erectile dysfunction or incontinence.
