title: Unusual presentation of ectopic insertion of duplicated collecting system in an adult male.
abstract: 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.
