Direct vision internal urethrotomy on urethral stictur after prostatectomy

目的 :探讨前列腺术后并发尿道狭窄的治疗方法。方法 :1988～ 1998年对 2 5例前列腺术后并发尿道狭窄患者在直视下行尿道内切开术 ( DVIU ) ,其中 1988～ 1990年收治 9例行狭窄段12、4、8点放射状切开 ,1991～ 1998年收治的 16例按照狭窄部位行不同点位的内切开。结果 :1988～ 1990收治的 9例术后出现不同程度的并发症 ,1991～ 1998年收治的 16例手术效果满意 ,并发症明显降低。结论 :前列腺术后尿道狭窄环的切开点应遵循狭窄部位、长度、瘢痕的多少及深度进行选择的原则 ,并注意尿道解剖特点。

Purpose:To study the treatment methods of urethral stricture after prostatectomy.Methods:From Jan 1988 to Feb 1998,we operated on 25 patients by DVIU.At the beginning we cut the stricture at 4,8,12 clock to all 9 cases.After 1991,we selected different clock according to the site of stricture.Results:The first 9 cases usually complicated with uroclepsia.After 1991,we changed the method of operation and acquired better effects than before.The ceomplication was distinctly reduced.Conclusins:To the urethral stricture after prostatectomy,the site of cuts should be determined by the position,the length,the cicatrix and the deep of the stricture.It should be also considered to the function of urethra after prostatectomy.
