Treatment of complex renal calculi with percutaneous nephrolithotomy using fourth generation Swiss LithoClast Master (report of 52 cases)

Objective: To explore the clinical efficiency and experience of percutaneous nephrolithotomy (PCNL) with the fourth generation Swiss LithoClast Master in treating complex renal calculi. Methods: We retrospectively probed 52 patients who performed PCNL for complex renal calculi with the advanced fourth generation Swiss LithoClast Master and neotype nephroscopy. Results: 47 cases were successful underwent one-stage PCNL, 2 cases needed two-stage PCNL and 3 cases reieved postoperatively EWSL. The operation time was74 minutes±24, estimated blood loss volume was 0.61g/L±0.59 and the residuals stone rate was 14.4%±9.3%. Postoperatively 3 cases of severe bleeding ocurred, no severe complication was observed intraoperatively. Conclusions: The combined application of pneumatic and ultrasonic power in the fourth generation Swiss LithoClast Master appears to be efficacious and safe for disintegrating and removing complex renal calculi1.
