ABSTRACT

Rental stone disease is an etiologically heterogenous problem associated with a high rate of recurrence. The biochemical profile of urinary calculi removed from the urinary tract of 48 patients in urology ward, Mayo Hospital Lahore was determined. The distribution of stone analysis was calcium oxalate with uric acid 46%, calcium oxalate with phosphate 27%, pure calcium oxalate 19%. Magnesium ammonium phosphate with calcium oxalate 6%, and pure uric acid 2%. The incidence of urolithiasis in upper urinary tract was higher than lower urinary tract in adults.
