Abstract
Percutaneous nephrolithotomy was performed on 175 cases in our clinic during these 33 months. Clinical success was recognized in 99% of cases (complete removal=92%). Ten percents of these cases were treated with continous wave YAG laser irradiation. Laser litholapaxy is more effective than the other two methods of stone disintegration (intensive ultrasound and electrohydraulic effect) in cases, where stones have dark colour, smooth surface or soft (organic) components.
