Long-term outcomes and risk factors for erectile dysfunction and penile curvature after surgical penile fracture repair.

Abstract

Long-term outcomes of penile fracture (PF) include erectile dysfunction (ED) and penile curvature. In this study, we aimed to present the functional and anatomical results of 182 patients who underwent PF repair surgery and to reveal the risk factors for ED and penile curvature in a relatively long follow-up period. Thirty (16.5%) patients suffered from ED and 18 (9.9%) patients had penile curvature, respectively in a median follow-up period of 66 (39-111) months. Presence of bilateral fractures (OR = 7.806; 95% CI = 2.083-29.261; p = 0.002), larger tunical defect size (OR = 1.099; 95% CI = 1.036-1.164; p = 0.002) and longer time between fracture and surgery (OR = 1.095; 95% CI = 1.036-1.157; p = 0.001) were stated as the independent risk factors for ED. Only larger tunical defect size was found as an independent risk factor for penile curvature (OR = 1.14; 95% CI = 1.063-1.221; p < 0.001). The cut-off values for predicting ED were 18.5 mm for tunical defect size, 14.5 h for time between fracture and surgery, and 41 years for age. The cut-off value for tunical defect size was 18.5 mm for penile curvature. Risk of ED increases among patients with extended tunical rupture and delayed surgical repair. Penile curvature manifests less frequently and seems to be associated with the size of the tunical defect.
