PCNL (percutaneus nephrolithotomy) is most widely used procedure for treatment of large renal stones. A most common complication in PCNL is bleeding. Decreasing the size of the percutaneus tract can reduce morbidity.

We present our  initial experience with PCNL performed through 4,85 FR needle with 0,9 mm optic and 200 micrometers laser fiber in 3 cases. One more case was performed with 8 FR shaft and ultrasonic probe. Stone size varied from 8 to 15 mm. All 4 patients were successfully treated with no morbidity.

Micro PCNL is efficacious for small volume renal stones. It may be alternative for flexible uereteroscopy for difficult cases previously treated by SWL
