Percutaneous Nephrolithotomy Combined with Pneumatic Lithotripsy for Renal Calculi:Report of 95 Cases / 中国微创外科杂志

ABSTRACT

Objective To investigate the efficacy and safety of percutaneous nephrolithotomy (PCNL) combined with pneumatic lithotripsy for renal stones. Methods Clinical data of 95 cases of renal stones that were treated by PCNL from February 2007 to September 2008 were retrospectively analyzed. The operations were done by using ultrasonography and pneumatic lithotripter system (EMS Ⅲ). If the stones were easy to shatter,we used ultrasonic lithotripter,otherwise,pneumatic lithotripter or both of them were employed. Results The procedures were completed successfully in all of the 95 cases with the operation time ranged from 45-170 min (mean,85 min). No severe complications including pleural trauma and severe bleeding occurred during the operations. After the operation,9 patients had fever and 11 cases showed severe hemorrhage (9 of them were cured by conservative therapy and the other 2 recovered after nephrectomy). In the 95 patients,17 cases had residual stones,6 of them received a second operation. Conclusion PCNL combined with pneumatic lithotripsy is an effective and minimally invasive method for the treatment of renal stone.
