PREOPERATIVE EVALUATION OF ERECTILE FUNCTION WITH DYNAMIC INFUSION CAVERNOSOMETRY CAVERNOSOGRAPHY IN PATIENTS UNDERGOING SURGERY FOR PEYRONIES-DISEASE - CORRELATION WITH POSTOPERATIVE RESULTS

Most reports of surgical therapy for Peyronie's disease to date have not included detailed preoperative assessment of erectile function. To evaluate the relationship between preoperative erectile function and postoperative success, we reviewed 25 consecutive patients with Peyronie's disease who underwent surgery and evaluation with dynamic infusion cavernosometry and cavernosography preoperatively. Overall results of dynamic infusion cavernosometry and cavernosography revealed corporeal veno-occlusive dysfunction in 76% of the patients and inadequate arterial inflow parameters in 44%. Among 20 patients treated with plaque excision and dermal graft inlay, adequate postoperative erectile function for satisfactory intercourse occurred in 4 of 4 (100%) with an equilibrium accumulated intracorporeal pressure of greater than or equal to 70 mm. Hg, 9 of 12 (75%) with an equilibrium accumulated intracorporeal pressure of 40 to 65 mm. Hg and 1 of 4 (25%) with an equilibrium accumulated intracorporeal pressure of less than 35 mm. Hg. These data may be helpful to counsel patients before surgical therapy, and may explain some of the disparate results previously reported after plaque excision and dermal graft inlay on the basis of patient selection.
