Home modeling after penile prosthesis implantation in the management of residual curvature in Peyronie's disease.

Abstract

The aim of this study was to study the clinical effectiveness of a structured home modeling (HM) protocol in Peyronie's disease (PD) patients who have residual curvature up to 45° after inflatable penile prosthesis (PP) placement. A total of 92 patients with PD and coexistent refractory erectile dysfunction received inflatable PP. If residual curvature after manual modeling (MM) was more than 45°, incision-grafting was performed. If curvature was <45° after MM, patients were instructed to perform HM daily for 6 months, after 4 weeks from PP implantation. The mean preoperative penile curvature was 39.4 ± 5.7° (30-60). Sixteen (17.4%) patients required incision-grafting and the remaining 76(82.6%) patients followed HM protocol. The mean postoperative residual curvature after MM was 29.7 ± 3.2° (5-50). Sixty-five (85.5%) patients who underwent HM had 10° or less residual curvature after 3 months and 72 (94.7%) patients had 10° or less residual curvature after 6 months. Seventy (92.1%) patients responded as satisfied or very satisfied on the questionnaire with the outcome after 6 months. HM of the penis over Inflatable PP may straighten the penis without the need for an additional surgical maneuver in vast majority of the PD patients having residual curvature of <45°.
