Abstract
Objective To assess the efficacy and safety of the low-power holmium laser with mini-percutaneous nephrolithotomy and extracorporeal shock wave lithotripsy for complex renal calculi. Methods The Low-power (20 W:0.6-0.8 J×10-20 Hz) holmium laser was used for mini-percutaneous nephrolithotomy and extracorporeal shock wave lithotripsy in 31 patients. The duration of stone surgery,stone-free rate and complication were assessed. Results The mean duration of stone surgery was 85 min (60-120 min),the stone-free rate was 87.09%(27/31) at the end of session. The average estimated blood loss was 80ml and 3 patients had got a high fever after mini-percutaneous nephrolithotomy,no other adverse events were noted. Conclusions The low-power holmium laser with mini-percutaneous nephrolithotomy and extracorporeal shock wave lithotripsy is a safe and efficient technique for the treatment of complex renal calculi.
