报告前列腺增生摘除术后膀胱颈挛缩（ＢＮＣ）１４例，其中开放前列腺摘除术后ＢＮＣ５例（４．１６％）；同期外院转来ＢＮＣ９例。１０例在直视下行膀胱颈切开瘢痕切除，１例行膀胱颈楔形切除，疗效满意；３例尿道扩张，仅１例恢复排尿通畅，２例疗效差。认为ＢＮＣ主要发生于小体积ＢＰＨ，尤其是合并长期慢性前列腺炎病史者，故无论是开放手术或ＴＵＲＰ，术中均应高度注意操作技巧，尽量避免ＢＮＣ的发生；一旦发生，应作直视下内切开瘢痕切除。 Reported 14 cases of bladder neck contracture (BNC) after radical prostatectomy, including 5 cases of BNC after open prostatectomy (4.16%); 9 cases of BNC were transferred to outside hospital during the same period. Ten cases underwent bladder neck incision scar excision and one case underwent bladder neck wedge resection with satisfactory curative effect. Three cases had urethral dilatation, and only one case had urinary patency recovery, and two cases had poor curative effect. That BNC mainly occurs in a small volume of BPH, especially in the history of chronic prostatitis combined with long-term, so both open surgery or TURP, surgery should pay great attention to operating skills, to avoid the occurrence of BNC; once occurred, should be under direct vision Internal incision scar excision.
