Plaque incision and grafting (PIG) surgery for Peyronie's disease (PD) is a recognized management strategy. One of the recognized complications of PIG surgery is the development of postoperative erectile dysfunction (ED).
To determine the incidence of ED after PIG surgery and attempt to define predictors of ED development.
All patients underwent preoperative cavernosometry. Grafting was performed with either cadaveric pericardium (Tutoplast) or intestinal submucosa (Surgisis). Prior to 2006, the procedure used an H-type incision, whereas after this date, the Egydio approach has been used.
Men undergoing PIG completed preoperative and 6-month postoperative International Index of Erectile Function (IIEF) questionnaires.
56 patients were analyzed. Mean patient and partner ages were 57 ± 22 and 54 ± 18 years, respectively. Mean duration of PD at the time of PIG was 22 ± 9 months. Seventy-five percent had curvature alone, 11% had hourglass/indentation deformity, and the remainder had combined curvature/indentation. Mean preoperative curvature was 52 ± 23°. Fifty-two had grafting with Tutoplast, while four had grafting with Surgisis. All men at baseline were capable of generating a penetration rigidity erection. Preoperatively, 50% of men had cavernosal insufficiency and 21% had venous leak (baseline and postoperative erectile function [EF] domain scores were 23 ± 4 and 17 ± 9, respectively [P < 0.01]). Forty-six percent of men experienced a ≥6-point decrease in EF domain score after PIG. The predictors of a ≥6-point reduction in IIEF-EF domain score on multivariable analysis were degree of preoperative curvature, type of plaque incision, patient age, and baseline venous leak.
Almost one-half of men had significant reduction in their erectile rigidity after PIG. Reduction was predicted by larger baseline curvature, the Egydio plaque incision technique, older patient age, and the presence of venous leak at baseline. Based on these data, we discourage older men, those with venous leak, and those with profound curvature from considering PIG surgery.
