Abstract:

【Abstract】 Objective To evaluate the clinical effect of percutaneous ephrolithotomy(PCNL) for huge renal calculus in different position: prone and semisupine-lithotomy position. Methods From March 2011 to March 2013,.a total of 84 patients with huge renal calculus underwent PCNL in different position: semisupine-lithotomy position (A group) and prone position (B). Operation time, blood loss, primary stone clearanceand complications were recorded and compared between two groups. Results PCNL was successfully completed in all the patients,.no one converted to open surgery. Single-tract PCNL was performed for 47 cases in semisupine-lithotomy groups, two tracts 1 case. The all patients in prone position group were treated with single-tract PCNL..The mean operation time in group A was less than that in group B..The stone free rate was 88.3% and 81.2% in semisupine-lithotomy group and prone position group respectively..One case appeared secondary bleeding in prone position group who was cured by conservative treatment. There were no severe complications occurred in both groups.Conclusion PCNL in semisupine-lithotomy position is an effective alternative for treating renal calculus..The semisupine-lithotomy position allows easier irrigation of stone fragments..It is more comfortable for the patient during operation and facilitates monitoring of anesthesia.
