A 5-year-old girl presented with continuous wetting with normal voiding pattern since birth. Ultrasonography (USG) showed a solitary left kidney. Excretory urography showed a normal left kidney. Right kidney was not seen but lower ureter was faintly delineated. Hence, contrast enhanced computed tomography (CECT) was done to look for any right kidney which was not seen on USG. CT showed a normal left kidney with a small ectopic kidney in right hemipelvis but ureteric orifice could not be traced to its insertion. Dimercaptosuccinic acid confirmed it to be a poorly functioning (6%) ectopic right kidney. Cystourethroscopy and vaginoscopy done could not localize the right ureteric orifice. The child underwent right nephrectomy along with excision of ectopic ureter inserting into vagina with complete resolution of her symptoms.
