Allthe patients undergoing pelvic urologic surgery at our Institution between November 2002 andDecember 2003 were considered. Preoperative erectile function (EF) was evaluated by using theabridged five-item version of the International Index of Erectile Function (IIEF5) questionnaire.
Study population was divided into separate groups considering grade of preoperative EF, nervesparing (NS) surgery and type of procedure (radical prostatectomy, radical cystectomy (RC) ornerve and seminal sparing cystectomy). In total, 86 patients were evaluated. After 6 months,an increase in mean IIEF5 score of 12.9 points was found in those who had undergone a bilateralNSRP after vardenafil therapy, of 8.0 points in those who had undergone unilateral NSRP, of 11.3in those who had undergone NSRC and of 11.5 in nerve and seminal sparing cistectomies. Abetter vardenafil response was found in patients with SE þ (Po0.001). Among those vardenafilnotresponders, 13 were treated by using intracavernous injections, one by vacuum device and threewith penile prosthesis implant. In conclusion, in our experience, vardenafil showed to be welltolerated and effective for recovery of EF in patients undergoing pelvic urologic surgery. This drugwas particularly effective for those with a normal preoperative EF undergoing an NS procedure. Ofcourse, it should be recognized that the absence of a control group in the study represents animportant limitation. However, based on the data from the literature, there is a strong belief thatsuch an approach will lead to an earlier recovery of EF than without rehabilitative treatment.
