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.
在患有膀胱外输尿管异位的男性患者中，异位开口不会导致尿失禁，诊断往往会延迟。我们描述了12例患有膀胱外输尿管异位的男性患者的治疗经验。根据导致此类异常的胚胎学现象，我们将其分为中肾管异位和泌尿生殖窦异位。讨论了这两种类型输尿管异位的独特临床和放射学特征。手术治疗指南基于异位的类型、患肾或肾段的功能以及受影响的是单一还是重复输尿管系统。
