To evaluate the ability to obtain and the quality of orgasm after radical prostatectomy.
The orgasms experienced after undergoing radical prostatectomy were evaluated in 20 men (median age 65 years, range 56-76) using a semi-structured interview and a self-administered questionnaire. In addition, the patients were asked to write a brief statement about their experiences and sensations during orgasm before and after the operation.
Eighteen patients returned the questionnaire and 17 completed a statement indicating what their orgasm was like before and after radical prostatectomy. After the operation, no patient was able to maintain a completely rigid erection, but for five patients the erection was sufficient for sexual intercourse. Nine patients used a vacuum device or intracavernosal self-injection. Half the patients reported diminished sexual desire (libido) and arousal after the operation and reported the same to occur in their partners. During their "dry' orgasm post-operatively, none of the patients experienced the exquisite sensation of inevitability, the so-called "point of no return'. Seven of the 14 patients experiencing orgasm complained that their orgasmic sensation was weakened. Four patients reported normal pleasure and sensation compared to that experienced pre-operatively. Surprisingly, nine of the 14 patients had involuntary loss of urine at orgasm; for five of them this was sufficient reason to avoid any sexual contact with their partner.
Radical prostatectomy may have serious consequences on libido and erectile function but sometimes other important factors, such as the absence of prostate and seminal vesicle contractions, the loss of ejaculation and involuntary loss of urine, may also compromise the orgasm.
评估根治性前列腺切除术后获得性高潮的能力及性高潮质量。
采用半结构化访谈和自填式问卷，对20名接受根治性前列腺切除术的男性（中位年龄65岁，范围56 - 76岁）术后经历的性高潮进行评估。此外，要求患者就手术前后性高潮期间的经历和感受写一份简短陈述。
18名患者返回了问卷，17名完成了一份陈述，表明他们根治性前列腺切除术前、后的性高潮情况。术后，没有患者能够维持完全坚硬的勃起，但有5名患者的勃起足以进行性交。9名患者使用了真空装置或海绵体内自我注射。一半的患者报告术后性欲（ libido ）和性唤起减弱，并表示其伴侣也有同样情况。在术后“干性”性高潮期间，没有患者体验到那种美妙的不可避免的感觉，即所谓的“无法回头点 ”。14名有性高潮的患者中有7名抱怨他们的性高潮感觉减弱。4名患者报告与术前相比性快感和感觉正常。令人惊讶的是，14名患者中有9名在性高潮时有不自主的尿液流失；其中5名患者以此为由避免与伴侣进行任何性接触。
根治性前列腺切除术可能对性欲和勃起功能产生严重影响，但有时其他重要因素，如前列腺和精囊收缩缺失、射精丧失和不自主尿液流失，也可能损害性高潮。
