To describe our experience of penile urethral repair and reconstruction, cataloguing the change in practice from one-stage flap to two-stage free graft procedures for anterior urethroplasty.
Between January 1992 and December 1996, 79 patients underwent anterior urethroplasty. Of the 45 one-stage bulbar patch urethroplasties, 37 (76%) used buccal mucosal free grafts rather than flaps. Of the 34 penile urethroplasties, 26 (82%) (including all of the circumferential reconstructions) were two-stage procedures.
Buccal mucosal free grafts were at least as good as local skin flaps for patch urethroplasty and two-stage repairs gave much better results than one-stage repairs for total circumferential reconstruction of the penile urethra.
For a patch urethroplasty of an uncomplicated stricture in the bulbar urethra, buccal mucosal free grafts are now the material of choice. For a patch urethroplasty of an uncomplicated stricture in the penile urethra the Orandi procedure remains the 'gold standard'. For a circumferential repair of the urethra, particularly the penile urethra, a two-stage repair using a free graft gives better results than a one-stage repair using a flap.
描述我们在阴茎尿道修复与重建方面的经验,梳理前尿道成形术从一期皮瓣手术到二期游离移植手术的实践变化。
1992年1月至1996年12月期间,79例患者接受了前尿道成形术。在45例一期球部补片尿道成形术中,37例(76%)使用颊黏膜游离移植片而非皮瓣。在34例阴茎尿道成形术中,26例(82%)(包括所有环形重建手术)为二期手术。
颊黏膜游离移植片在补片尿道成形术中至少与局部皮瓣效果相当,对于阴茎尿道全周重建,二期修复比一期修复效果好得多。
对于球部尿道单纯狭窄的补片尿道成形术,颊黏膜游离移植片是目前的首选材料。对于阴茎尿道单纯狭窄的补片尿道成形术,奥兰迪手术仍是“金标准”。对于尿道的环形修复,尤其是阴茎尿道,采用游离移植的二期修复比采用皮瓣的一期修复效果更好。
