Sexual function was evaluated in 21 patients with bladder carcinoma who had undergone radical cystectomy either with (n = 9) or without (n = 12) excision of the urethra. All patients received preoperative radiotherapy, and the cystectomy was done by a nerve-sparing surgical technique. At follow-up all patients reported normal sexual desire and tactile sexual activity. Eight of the 12 patients in whom the urethra was preserved could achieve penile erection and orgasm to tactile stimulation, and five of them had sufficient strength and duration of erection for sexual intercourse. Two of the nine patients in whom the urethra was removed-had weak erections insufficient for intercourse; three could experience orgasm. These results show that when cystectomy is done by a nerve-sparing technique and without urethrectomy there is more chance of preserving sexual function than when simultaneous urethrectomy is done.
对21例膀胱癌患者的性功能进行了评估，这些患者均接受了根治性膀胱切除术，其中9例切除了尿道，12例未切除尿道。所有患者均接受了术前放疗，膀胱切除术采用保留神经的手术技术。随访时，所有患者均报告性欲和触觉性活动正常。保留尿道的12例患者中有8例能通过触觉刺激实现阴茎勃起和性高潮，其中5例勃起强度和持续时间足以进行性交。切除尿道的9例患者中有2例勃起较弱，不足以进行性交；3例能体验到性高潮。这些结果表明，采用保留神经技术且不切除尿道进行膀胱切除术时，保留性功能的机会比同时切除尿道时更多。
