[Detailed evaluation of sexual function after radical prostatectomy: is patient satisfaction correlated with the quality of erections?].

INTRODUCTION

Post radical prostatectomy potency rates, quantified on the basis of physician survey, have ranged up to 80%. Physician derived potency data, however, may not be representative of true post-prostatectomy potency rates or more importantly may not accurately portray patients' post-operative sexual satisfaction. We conducted a pilot study combining physician derived and patient derived subjective data with objective measures of erectile function.

MATERIALS AND METHODS

Eleven men, mean age of 59 years, who were treated with nerve sparing radical retropubic prostatectomy formed the study group. Initially, the patients responded to a physician directed telephone survey on sexual status. Potency was then objectively assessed utilizing Rigiscan testing on two consecutive evenings. Lastly, the patients completed a validated short questionnaire directed to obtain a patients' subjective perception of sexual function.

RESULTS

All the patients responded to the first part of the study by informing the physician that they were sexually active or potent after radical prostatectomy. Of these 11 patients, however, only 2 (18%) were mostly satisfied with their sex life according to the quality of life questionnaire. Rigiscan testing revealed that 8 of the 11 patients had nocturnal erections which were adequate for vaginal penetration. Of the 5 patients who stated that they were mostly dissatisfied with their sexual functioning, 3 had objective evidence of adequate erectile ability as documented by Rigiscan. Three of the four patients who were ambivalent with respect to their sexual function also demonstrated objective evidence of normal erectile activity.

CONCLUSION

Although a patient may inform his care provider that he is sexually active or potent, he may not be satisfied with his present level of sexual functioning. In addition, we observed that some dissatisfied patients do have normal Rigiscan patterns indicating that a percentage of patients who are not happy with their level of sexual function after radical prostatectomy may have a psychogenic component to their problem.
