摘要
Purpose: The response to sildenafil after radical retropubic prostatectomy (RRP) has been reported to be approximately 40% by the Sildenafil Study Group. We undertook a study in a large cohort of post-RRP erectile dysfunction (ED) patients in order to examine the relationship between satisfaction with sildenafil and time from surgery to start of sildenafil treatment. Methods: Pre- and post-operative erectile function was assessed by the O'Leary Brief Sexual Function Inventory questionnaire. Patient satisfaction with sildenafil before and after sildenafil treatment was assessed by the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire. Between April and October 1998, EDITS questionnaires were given to 579 patients who had undergone RRP between 1994 and 1998. 316 (55%) patients returned questionnaires. Of these, 198 (63%) had sildenafil treatment and completed post-treatment questionnaires and were included in the study group. Results: In the study group, mean age was 61y. Pre-operatively, 92% had erections sufficient for vaginal penetration, 95% had bilateral nerve-sparing (NS) RRP, There was a significant increase in the treatment satisfaction rate with increasing time from surgery. Between zero and six months after surgery, the treatment satisfaction rate was 26%, Which improved with time, peaking at 60% between 18 months and 2y. Self-perceived erectile function as determined by post-RRP pre-sildenafil treatment O'Leary questionnaires was not as predictive of response to sildenafil as time from surgery. Conclusions: The response to sildenafil appears to be dependent upon the interval between RRP and the start of sildenafil, The treatment satisfaction rate was found to peak at 60% between 18 months and 2y, Early nonresponders to sildenafil should not be disheartened, as they will more likely later respond.
