The ectopic ureter is an uncommon presentation in the pediatric population with a 6 to 1 female-to-male prevalence. From an embryologic standpoint, ectopic ureters form as a result of failure of proper development of the urogenital sinus with ectopic development of the ureteral orifice. They are most often associated with a duplicated collecting system. The location of the orifice is most commonly in the posterior urethra. Diagnosis is usually made with a combination of multiple imaging modalities, including ultrasonography, voiding cystourethrography, nuclear scintigraphy, and sometimes CT or MRI. In this review, we detail the origin of the ectopic ureter and discuss diagnosis and medical management.
