Peyronie's disease: urologist's knowledge base and practice patterns.

Peyronie's disease (PD) is a poorly understood clinical entity. We performed an in-depth analysis of the knowledge base and current practice patterns of urologists in the United States. A 46-question instrument was created by two experienced PD practitioners and emailed to current American Urology Association members nationally. Questions were either multiple-choice or used a visual analogue scale. Responses regarding treatment options were answered by ranking a list of utilized therapies by preference. Data were aggregated and mean values for each category compiled. Responses were received from 639 urologists (67% in private practice). Almost all (98%) reported seeing PD patients with regularity. Twenty-six percent believed PD prevalence is ≤1%, a small fraction (5%) reporting prevalence as ≥10%. Only 3% referred patients to a subspecialist in PD. Twenty-six percent believed PD is a condition that does not warrant any treatment. The preferred initial management was with oral agents (81%). Of those who used intralesional injections as first line, verapamil was most commonly selected (67%). Seventy-nine percent perform surgery for PD with 86% reporting the optimal timing at ≥12 months after onset of symptoms. Seventy percent perform penile plication, most commonly the Nesbit technique (54%), 61% perform implant surgery and 37% reported performing plaque incision/excision and grafting. Although PD is now a more recognized condition, there are still large variances in knowledge and management strategies. Prospective clinical studies are needed to elucidate standardized management guidelines and a more cohesive strategy to manage this common disease.
