Percutaneous nephrolithotomy for renal calculi complicating with ureteropelvic junction stenosis in 56 patients

Abstract

Objective To analyze and explore the clinical efficacy of percutaneous nephrolithotomy for renal calculi complicating with ureteropelvic junction stenosis.Methods The clinical data of 56 patients with renal calculi complicating with ureteropelvic junction stenosis undergoing percutaneous nephrolithotomy from our hospital from May 2008 to May 2011 retrospectively analyzed.The clinical efficacy was summarized and discussed.Results all patients' operations were completed in one stage operation with 60-110 minutes operation time.Bleeding volume during operation was 50-150 ml.No serious complications occurred.Postoperative follow-up revealed patients symptoms had different degrees of ease and patients with hydronephrosis were relieved.Conclusions Percutaneous nephrolithotomy for renal calculi is significantly efficacious,safe,fast recovery and has low complication rate and high stone-free rate.It's a first-line therapy for renal calculi complicating with ureteropelvic junction stenosis.
