We present our experience with the reconstruction of synchronous urethral strictures.
Of 482 anterior urethroplasties performed by a single surgeon between 1997 and 2008 we identified and reviewed 30 patients who underwent reconstruction for multiple separate strictures. An ascending approach from distal to proximal was used and all repairs were completed at 1 stage. A total of 13 combinations of techniques were used to complete the repairs. A 2-phase technique was used in which the patient remained supine during buccal mucosa harvest and repair of strictures distal to the penoscrotal junction, and was then repositioned into the high lithotomy position as needed for stricture repair in the bulbar urethra. In each case normal intervening urethra was preserved intact. The number, length and location of strictures, operative time and patient outcomes were evaluated.
No position related complications occurred during or after surgery despite a mean operative time of 4.5 hours (range 2.5 to 6.4). No infectious wound complications were reported despite repositioning the legs to the high lithotomy position. Three patients (10%) were known to have required treatment for recurrent stricture after surgery.
One-stage reconstruction for synchronous urethral strictures may be safely and effectively performed using a systematic, ascending reconstructive approach with creative application of tissue transfer techniques. Decreasing patient time in the high lithotomy position appears to prevent related lower extremity complications.
我们介绍同步性尿道狭窄重建的经验。
在1997年至2008年间由一位外科医生实施的482例前尿道成形术中,我们识别并回顾了30例接受多处独立狭窄重建的患者。采用从远端到近端的逆行入路,所有修复均在一期完成。共使用了13种技术组合来完成修复。采用两阶段技术,在采集颊黏膜及修复阴茎阴囊交界处远端狭窄时患者保持仰卧位,然后根据需要重新摆放至高位截石位以修复球部尿道狭窄。在每种情况下,正常的中间尿道均保持完整。对狭窄的数量、长度和位置、手术时间及患者预后进行了评估。
尽管平均手术时间为4.5小时(范围2.5至6.4小时),但手术期间及术后均未发生与体位相关的并发症。尽管将腿部重新摆放至高位截石位,但未报告有感染性伤口并发症。已知有3例患者(10%)术后因复发性狭窄需要治疗。
同步性尿道狭窄的一期重建可通过系统性逆行重建方法并创造性地应用组织移植技术安全有效地进行。减少患者处于高位截石位的时间似乎可预防相关的下肢并发症。
