Long-term results of anterior and posterior urethroplasty with actuarial evaluation of the success rates.

PURPOSE

We analyzed the long-term results of different urethroplasty techniques.

MATERIALS AND METHODS

We performed a retrospective review of 98 patients who underwent different procedures for anterior (78) and posterior (20) urethral strictures. Mean followup was 53 months. A total of 20 patients underwent end-to-end anastomosis (group 1), 30 underwent 1-stage procedures (group 2), 28 underwent 2-stage procedures (group 3), and 20 underwent bulboprostatic anastomosis (group 4). The results were analyzed using Kaplan-Meier curves and log rank test.

RESULTS

The success rate was 95% for group 1, 93.4% for group 2, 78.6% for group 3, and 70% for group 4. Statistical evaluation of the actuarial success rates failed to show significant differences among the 4 groups.

CONCLUSIONS

The stricture recurrences were uniformly distributed over time. Urethroplasty patients must be followed for the rest of their lives.
