Abstract

Objective This study aimed to present our experience of concomitant management of renal calculi and recurrent ureteropelvic junction obstruction (UPJO) with percutaneous nephrolithotomy (PCNL) and antegrade balloon dilation. Methods We retrospectively reviewed 31 patients who underwent PCNL and antegrade balloon dilation for treatment of renal calculi and recurrent UPJO. The inclusion criterion was the presence of UPJO after failed pyeloplasty with ipsilateral renal calculi. Success was defined as achievement of both symptomatic and radiographic resolution of any stones and obstruction. Results All operations were successful without grade III or higher postoperative complications. A stone-free status was observed in all patients and the overall success rate of the procedure was 87.1% (27/31). The success rate of the procedure was significantly higher in patients with mild or moderate preoperative hydronephrosis (96%) than in those with high-grade preoperative hydronephrosis (50%). Moreover, the success rate of the procedure was lower in patients with poor preoperative renal function (0%) than in those with good or moderate renal function (93.1%). Conclusion Combined PCNL and antegrade balloon dilation management represents a safe and effective approach for patients with renal calculi and recurrent UPJO after failed pyeloplasty.
