Title: Minimally invasive percutaneous nephrolithotomy in the treatment of renal calculi under ultrasound guidance(report of 98 cases)
Abstract: Objective To investigate the efficacy and safety of the treatment of nephrolithiasis by minimally invasive percutaneous nephrolithotomy(MPCNL) with lithotripsy under ultrasound guidance.Methods The clinical data of 98 cases with renal calculi underwent MPCNL during Oct.2005 to Nov.2007 was retrospectively reviewed.Of the cases,42 had staghorn calculi,27 had simple calculi,and 29 had multiple calculi.Results The percutaneous renal access was successfully established under ultrasound guidance in all patients.68 cases were treated with one-stage operation(69.4%),19 with two-stage operation(19.3%).The operative time and stone-free rate were(97±21)min and 59.5% in staghorn calculi,(71±13)min and 77.8% in simple calculi,and(101±18)min and 72.4% in multiple calculi.No severe complication was noted during nephrolithotripsy.Conclusion The treatment of nephrolithiasis using MPCNL appears to be effective and safe under ultrasound guidance.
