Forty-three men who had been subjected to cystectomy and concomitant prostatectomy, vesiculectomy and urethrectomy were interviewed about their pre-operative and post-operative sexual activities at a mean of 3 (range 1 to 8) years after operation. Twenty-eight of the 38 men (74%) who had been sexually active continued to have some form of sexual activity, 21 of them achieving orgasm. Only 3 men had penile erection; 2 of them had been subjected to prostatectomy and 1 to prostatic resection. One of these men treated by prostatectomy had also had urethrectomy. Electromyographic registration from the striated external urethral sphincter, the bulbocavernosus muscle and the levator ani muscle showed normal duration of muscular contractions and length of interval between contractions after operation. The pattern of impulses during organs did not differ from that of normal men.
对43名接受了膀胱切除术并同时进行前列腺切除术、精囊切除术和尿道切除术的男性，在术后平均3年（范围1至8年）时就其术前和术后的性活动进行了访谈。38名有性活动的男性中，28名（74%）继续有某种形式的性活动，其中21人能达到性高潮。只有3名男性有阴茎勃起；其中2人接受了前列腺切除术，1人接受了前列腺切除手术。接受前列腺切除术治疗的这些男性中有1人还接受了尿道切除术。对横纹肌外尿道括约肌、球海绵体肌和肛提肌的肌电图记录显示，术后肌肉收缩持续时间和收缩间隔长度正常。性活动期间的冲动模式与正常男性无异。
