Ectopic ureters are rare congenital mesonephric duct malformations with a higher prevalence in women than men. In women, ectopic ureters are often associated with a duplicated collecting system, whereas in men, ectopic ureters usually drain a single system and are associated with renal dysplasia and obstruction. Presentation and diagnosis generally occurs in the pediatric age group. Herein, we present an unusual case of delayed diagnosis of ectopic insertion of the upper pole ureter in a completely duplicated left kidney causing massive hydroureteronephrosis in an adult man.
异位输尿管是一种罕见的中肾管先天性畸形，女性发病率高于男性。在女性中，异位输尿管常与重复的集合系统有关，而在男性中，异位输尿管通常引流单一系统，并与肾发育不良和梗阻有关。其表现和诊断通常发生在儿童期。在此，我们报告了一例罕见的成人完全重复左侧肾脏中输尿管上段异位插入导致巨大输尿管积水的迟发性诊断病例。
