We analyzed the long-term results of different urethroplasty techniques.
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.
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.
The stricture recurrences were uniformly distributed over time. Urethroplasty patients must be followed for the rest of their lives.
我们分析了不同尿道成形术技术的长期结果。
我们对98例因前尿道狭窄（78例）和后尿道狭窄（20例）接受不同手术的患者进行了回顾性研究。平均随访时间为53个月。共有20例患者接受端端吻合术（第1组），30例接受一期手术（第2组），28例接受二期手术（第3组），20例接受球部前列腺吻合术（第4组）。结果采用Kaplan-Meier曲线和对数秩检验进行分析。
第1组成功率为95%，第2组为93.4%，第3组为78.6%，第4组为70%。对精算成功率的统计评估未显示4组之间存在显著差异。
狭窄复发随时间均匀分布。尿道成形术患者必须终身随访。
