[One-stage laparoscopic bilateral upper pole nephrectomy for ectopic insertion of complete ureteral duplication].

Ectopic ureteric insertion of the superior renal unit in the context of complete ureteric duplication is frequently accompanied by destruction of the corresponding parenchymal territory. Surgical treatment must comprise upper pole nephrectomy with partial ureterectomy. The authors report a case of one-stage retroperitoneal laparoscopic bilateral treatment which could become the treatment of choice of this disease.
