闭塞性后尿道狭窄治疗很困难。其最常见于机动车事故所致骨盆骨折或手术损伤。早期治疗常采用耻骨上膀胱造瘘及3～6月后的延期修补术。早期治疗后形成的尿道狭窄则采用经会阴或经耻骨,或联合开放性尿道成形术,这些手术的并发症较多,住院期较长。作者介绍一种腔内手术技术,并发症少,疗效好,简单,可在门诊完成。方法截石位,拔出耻骨上造瘘管,经瘘口插入21F30°的膀胱镜,并插入膀胱颈。同时经尿道插入20F0°尿道镜,很容易看到耻骨上膀胱镜的光线透过尿道瘢痕组织。前后活动耻骨上膀胱镜有助于识别后尿道的位置。用尿道冷刀于12点处短距离刺切,“切向亮处”,直
Obstructive posterior urethral stricture is difficult to treat. The most common cause of pelvic fractures or surgical injuries caused by motor vehicle accidents. Early treatment often used suprapubic cystostomy and 3 to 6 months postponed repair surgery. Urethral stricture formed after early treatment is via the perineum or the pubis, or combined with open urethroplasty. There are more complications and longer hospital stay. The author describes a technique of endovascular surgery with fewer complications and good curative effects that are simple and can be done in a clinic. Method lithotomy position, pull out the pubic symphysis fistula, 21F30 ° into the cystoscope through the fistula, and insert the bladder neck. At the same time the transurethral 20F0 ° urethral catheterization, it is easy to see the suprapubic cystoscope light through the urethral scar tissue. Posterior suprapubic cystoscopy helps identify the location of the posterior urethra. With urethral cold knife at 12 o’clock at a short distance stab, “tangential bright Department,” straight
