[Strangulated ureterocele and prolapsed urethral mucosa in a little girl. Diagnostic difficulties].

The author reports a case of a 2 year-old girl, with prolapse of the urethra treated since birth, twice by electro-coagulations. The persistence of the symptoms required further urological examinations (Urography, Ultrasonography), which revealed an ureterocele, prolapsed into the urethra with total duplication of the urinary tract. The operation consisted of a nephro-ureterectomy of the upper tract, with resection and suture of the exteriorized part of the ureterocele in the urethra.
