Duplex Collecting System With Ectopic Ureter Into the Posterior Urethra: A Case Report

Abstract

The ureters are muscular tubes that carry urine from the kidneys to the urinary bladder and are typically implanted in the superolateral angle of the trigone of the urinary bladder. Although renal anomalies are common, especially in the kidneys, ectopia of the ureter is rare. Clinical presentation depends on the insertion of the ectopic ureter, varying from asymptomatic (mostly in males) to recurrent urinary tract infections (UTIs) and incontinence (mostly in females). Radiology is the best diagnostic tool to achieve a diagnosis. Ultrasound (US), intravenous renogram (IVR), micturition cystourethrogram (MCUG), and others are used to diagnose ectopic ureters, with US and MCUG being the gold standard modalities. Treatment depends on the functionality of the part drained by the ectopic ureter. Heminephroureterectomy and ureteroureterostomy are among surgical treatments for ectopic ureter, and it is either open or laparoscopic surgery. Herein, we present a case of a four-year-old female patient who presented with recurrent UTIs and incontinence.
