Traumatic posterior urethral injury and early primary endoscopic realignment: evaluation of long-term follow-up.

OBJECTIVES: The management of complete or partial posterior urethral disruption is controversial and much debate continues regarding immediate versus delayed definitive therapy. We further analyze our experience and long-term results using early endoscopic realignment.

METHODS: Between April 1991 and June 1995, 8 men with posterior urethral avulsion, either complete or partial and secondary to blunt trauma and pelvic fractures, presented to our institution. A variety of endourologic techniques were employed to achieve urethral continuity while attempting to minimize stricture formation, incontinence, and impotence.

RESULTS: After a mean of 50.4 months (range 35 to 85) of follow-up, 7 men (87.5%) are continent, with 2 of those requiring intermittent self-dilation ranging from once every 7 days to once a month. One patient required conversion to an open perineal urethroplasty. Of the 8 patients, 5 (62.5%) are potent, and 2 others achieve adequate erections for intercourse using intracorporeal injections. Four of the 8 have required subsequent internal urethrotomies with eventual voiding stabilization over the course of 1 2 months. Average time to realignment was 9.5 days (range 0 to 19).

CONCLUSIONS: Primary endoscopic realignment offers an effective method for treating traumatic urethral injuries. Our long-term follow-up provides further support for use of this technique by demonstrating that urethral continuity can be established without increased incidence of impotence, stricture formation, or incontinence. By achieving early and minimally invasive realignment, we seem to lessen the severity of stricture disease that almost uniformly afflicts those patients who undergo delayed repair. If a minimally invasive technique should fail, it does not seem to delay nor does it preclude further management using open techniques.
