Abstract

We reviewed our experience over 10 years with pyeloplasty for ureteropelvic junction obstruction. Preoperative and postoperative isotope renal scans were performed to assess the surgical outcome, with particular emphasis on the postoperative change in renal function (RF). We retrospectively reviewed the medical records of 137 consecutive children with ureteropelvic obstruction operated between January 1994 and December 2003. A total of 109 kidneys in 102 patients were evaluated with renal echo and 99mTc-diethylenetriaminepentaacetic renography both before and after Anderson–Hynes dismembered pyeloplasty. The improvement of RF >5% was noted in 67 kidneys (61.5%), the function remained stable in 30 kidneys (27.5%), and it deteriorated (>5%) in 12 kidneys (11.0%). Five patients (4.6%) required repeat pyeloplasty for either prolonged urine leakage or reobstruction with deterioration in RF. Dismembered pyeloplasty in children with ureteropelvic junction obstruction is safe. The renal functional improvement can be expected in the majority of kidneys that have impaired function at presentation.
