Abstract
- The effects on renal function following percutaneous nephrolithotomy(PNL) were investigated on 37 patients. The overall success rate was 76%. The success rate on renal stone(79% ) was better than on upper ureter stone(67% ). The complication rate was much lower on later cases according to the increasing experiences and improved technique. The renal function was evaluated on 15 cases using DMSA renal scan and separate creatinine clearance rate pre-and post-operatively. Fourteen cases out of fifteen cases showed no significant renal functional change statistically. However, only one case who had massive renal bleeding for eight days postoperatively showed about 18% reduction of renal function and which case was considered due to major renal vascular damage during PCN tract creation. Conclusively, PNL seemed to be safer and has lower morbidity rate than surgical removal of stone if carried out by experienced hands.
