Objective :To assess the safety and feasibility of minimally invasive percutaneous nephrolithotomy(mPCNL) with ureteroscopic holmimium:YAG laser lithotripsy in duplex kidney calculi. Methods : A restrospective investigation was going on 11 cases suffering from duplex kidney calculi, who were treated with mPCNL with ureteroscopic holmimium:YAG laser lithotripsy from November 2005 to June 2010.Results : Of 11 cases, the stone- free rate was 100% after the first session. Conclusion :The MPCNL with holmium laser is an effective and safe technique for duplex renal calculi , and has the advantages of minimally invasion and low rate of complication. |
