title: [Treatment of extra-vesical ureteroceles associated with pyeloureteral duplication in children].
abstract: The authors report their experience of the treatment of the extra-vesical ureteroceles associated with pyelo-ureteral duplication. Twelve nephrectomies were performed because of the destruction of the kidney. A one stage complete repair (upper partial nephroureterectomy and excision of the ureterocele) was performed in 24 cases. It is a difficult technique but achieves good results (only three reoperations). The upper pole partial nephroureterectomy (simplified method, 31 cases) is easier to perform; twelve re-operations were necessary due to bladder outlet obstruction or vesicoureteral reflux. This complication is impossible to anticipate after the simplified method. Long term follow up is therefore essential after upper pole partial nephroureterectomy.
