110 patients underwent percutaneous stone extraction at our institution and we removed 99 per cent of renal stones and 77 per cent of ureteral stones.
For fragmentation and removal of large renal stones including staghoru calculi, Mazzariello-Caprini forceps and Kocher's forceps were found to be useful and safe instruments.
Indication and advantages of maneuver with these forceps were discussed.
