Objective To discuss whether preoperative extracorporeal shock wave lithotripsy (ESWL) could improve the efficacy of percutaneous nephrolithotomy (PCNL) for complicated renal calculi. Methods 160 cases of complicated renal calculi patients were divided into observation group (80) and control group (80) at random. Take conventional PCNL treatment for control group, and ESWL treatment one day before conventional PCNL treatment for observation group. Record the operation time, intraoperative blood loss, postoperative calculi clearance rate, complications, treatment costs, hospital stays of two groups of patients, then compare the curative effects between the two groups. Results Results are very different in the two groups, and the therapeutic effect of observation group is much better than control group (P < 0.05). Conclusions For complicated renal calculi, compared with conventional PCNL, in reducing the residual stone rate shorting the operation time, reducing the operation number, complications, treatment costs and the length of hospital stay, PCNL preoperative ESWL have obvious advantages. It is a kind of both economic and safe and effective treatment method.
