ABSTRACT

Objective To assess the safety and the curative effect of the combination of minipercutaneous nephrolithotomy (mini-PCNL) and ureteroscopic lithotripsy (URL) in the treatment of nonhydronephrotic staghorn calculi. Methods The clinical data of 53 eases with non-hydronephrotic staghom calculi treated by mini-PCNL combined with URL were retrospectively analyzed. Results Fifty-three cases (64 renal units) were performed first-stsge operation, 9 renal units were stone free in first-stage operation, 33 renal units were stone free in second-stage operation, other 13 renal units were stone free in third-stage operation. A complete stone clearance rate of 85.9%(55/64) was achieved, and after one to three sessions of mini-PCNL and extracorpereal shock wave lithotripsy afterwards that increased to 95.3% (61/64). Blood transfusion was performed in 3 cases, no major complication was noted in the patients. Conclusions The combination of mini-PCNL and URL has more advantages, less invasions, easier recovery and less complications. It provides a new minimally invasive way for non-hydronephrotic staghorn calculi.
