[Crossed dystopia of the kidney and an ectopic ureteral orifice].

We report on a case of crossed renal ectopia with fusion and a refluxing single ectopic ureteral orifice in the prostatic urethra in a renal transplant recipient. The diagnosis was made on the basis of a chronic urinary tract infection and a refluxing ectopic ureteral stump. Crossed ectopia with fusion was found intraoperatively. Nephroureterectomy cured the urinary tract infection.
