Many techniques have been described for the repair of recurrent urethral strictures. Experience with 1-stage correction of hypospadias and epispadias, using a vascularized island flap technique, has led to its increased application for complicated adult urethral strictures. The advantage of the vascularized island flap technique is that reconstruction can be completed with only 1 operation, and it provides good subjective and objective results. Analysis of 50 consecutive cases treated by this approach has proved its validity. Of the 50 cases fistulas occurred in 20%, of which 12% required surgical correction, and stricture recurred in 32%. The largest proportion of recurrence was noted in patients who were primarily treated with 3 or more urethrotomies within a short time. Therefore, we recommend open surgical repair when 1 or 2 internal urethrotomies fail to produce a good result.
已经描述了许多用于修复复发性尿道狭窄的技术。使用带血管蒂岛状皮瓣技术一期矫正尿道下裂和尿道上裂的经验，促使其在复杂的成人尿道狭窄治疗中的应用增加。带血管蒂岛状皮瓣技术的优点是仅需一次手术即可完成重建，并且能提供良好的主观和客观效果。对采用该方法连续治疗的50例病例的分析证明了其有效性。在这50例病例中，20%发生了瘘管，其中12%需要手术矫正，32%出现了狭窄复发。复发比例最高的是那些在短时间内接受过3次或更多次尿道内切开术的患者。因此，我们建议在1或2次尿道内切开术未能取得良好效果时采用开放手术修复。
