To evaluate the results of percutaneous nephrolithotomy in the treatment of staghorn stones.

The right kidney was treated alone in 42% of cases, the left one in 56% of cases and both kidneys in only two cases. The mean area of stones was 6,6 cm[2]. One renal puncture was necessary in 97% of cases. The rate of stone free after percutaneous nephrolithotomy only was about 54% and when combined with lithotripsy the rate was 64%. Combined treatment using percutaneous nephrolithotomy and lithotripsy is considered as the best procedure for staghorn stones treatment
