PCNL MONOTHERAPY FOR RENAL CALCULI - AN INITIAL EXPERIENCE.

Twenty nine cases of renal stone underwent treatment by way of percutaneous nephrolithotomy during a 6 month period. Of these, 13 patients had recurrent or residual stones. Majority of these stones were between 1-2 cm in size. A field operating table was modified for this purpose. In 26 cases the calyceal system was accessed through either of the inferior calyces. Twenty five of these patients underwent stone clearance in a single stage, 2 underwent two-stage surgery while there were 2 failures.
