A controlled, prospective clinical study was undertaken to determine the incidence and cause of urethral strictures after transurethral resection. Patients were assigned to 1 of 3 groups. Group A consisted of patients in whom it was considered preferable for various reasons to perform prostatic resection through perineal urethrostomy; therefore, these were excluded from randomization. All other patients were randomized using a sealed-envelope method into Group B who underwent resection via perineal urethrostomy and Group C who underwent resection via the entire urethra. Strictures occurred in 6 of 42 patients in Group C postoperatively while patients in Group B remained free of strictures. This difference was statistically significant (p less than 0.05). It was concluded that strictures which occur result from the use of the resectoscope through the entire urethra and not from the use of indwelling catheters, and that performing prostatic resection via perineal urethrostomy is valuable in preventing the occurrence of such strictures.
进行了一项对照性前瞻性临床研究，以确定经尿道切除术后尿道狭窄的发生率及原因。患者被分为3组中的1组。A组由因各种原因被认为通过会阴尿道造口术进行前列腺切除术更为合适的患者组成；因此，这些患者被排除在随机分组之外。所有其他患者采用密封信封法随机分为B组（通过会阴尿道造口术进行切除术）和C组（通过整个尿道进行切除术）。C组42例患者中有6例术后出现狭窄，而B组患者未出现狭窄。这种差异具有统计学意义（p小于0.05）。得出的结论是，狭窄是由于通过整个尿道使用电切镜所致，而非留置导尿管所致，并且通过会阴尿道造口术进行前列腺切除术对预防此类狭窄的发生具有重要价值。
