title: Extravesical ureteral ectopia in male patients.
abstract: In male patients with extravesical ureteral ectopia the ectopic orifice does not cause urinary incontinence and the diagnosis is often delayed. We describe our experience with 12 male patients who had extravesical ureteral ectopia. According to the embryologic phenomena leading to such anomalies we have classified them into mesonephric ductal ectopia and urogenital sinus ectopia. Distinctive clinical and radiologic features of these 2 types of ureteral ectopia are discussed. Guide lines to surgical therapy are based upon the type of ectopia, function of the affected kidney or renal segment and whether a single or duplicated ureteral system is affected.
