１９９２年１１月～１９９４年１月对３０例患者施行耻骨上前列腺摘除术，术前行膀胱测压术。发现１７例为不稳定膀胱，占５６．７％（１７／３０）。其中５例术后发生急迫性尿失禁，占２９．４％（５／１７）。文章对不稳定膀胱和前列腺摘除术后尿失禁之间关系进行了探讨，并提出手术前施行膀胱测压术有助于明确术后尿失禁发生的病因、预测尿失禁发生和指导尿失禁的治疗。 From November 1992 to January 1994, 30 patients underwent suprapubic prostatectomy and bladder pressure was performed preoperatively. 17 cases were found to be unstable bladder, accounting for 56.7% (17/30). Among them, 5 cases had urge incontinence after surgery, accounting for 29.4% (5/17). The article discussed the relationship between unstable bladder and urinary incontinence after prostatectomy, and proposed that the operation of bladder pressure before surgery can help to clarify the etiology of postoperative urinary incontinence, predict the occurrence of incontinence and guide the treatment of urinary incontinence .
