Supporting the role of penile trauma and micro-trauma in the etiology of Peyronie's disease. Prospective observational study using the electronic microscope to examine two types of plaques.

Objectives: The etiopathogenesis of Peyronie's disease (PD) remains not clearly understood. The most accepted theory attributes the histological lesions of PD to the effects of trauma to the corpora cavernosum of the penis. The aim of our study is to verify whether similar histological features exist between these two tissues, providing new evidence in favor of the traumatic theory in the etiopathogenesis of Peyronie's disease.

Cycling Trauma as a Cause of Arterial Priapism in Children and Teenagers.

Bicycle riding has multiple beneficial cardiovascular effects; however, it is a well-documented source of significant urologic injuries. Priapism is a rare condition in children, and occurs primarily because of congenital hematologic diseases or adverse drug reactions. A pediatric clinical case and literature review of a high-flow priapism secondary to cycling trauma is described here to highlight their etiopathologic correlation.

Inter-rater reliability in the radiological classification of renal injuries.

Introduction: Although many radiologists invoke the surgical classification of renal injury proposed by the American Association for Surgery in Trauma (AAST), there has been only limited work on the role of the AAST system as an imaging stratification. The aim was to determine the inter-rater reliability (IRR) amongst radiologists and urologists using the AAST system.

Methods: A 1-year retrospective study of consecutive patients with computed tomography (CT) evidence of renal trauma managed at a Level 1 trauma center.
