URINARY CALCULI

BIOCHEMICAL PROFILE OF STONES REMOVED FROM URINARY TRACT

Abstract

Objective: To describe frequency of urinary stones according to chemical composition in patients presenting. Study Design: Prospective & descriptive study Setting: Sh. Zayed Hospital, Rahim Yar Khan. Period: Dec 1998 to Dec 2000. Material & Method: Of 125 patients presenting with urinary Lithiasis. who were operated in surgical unit-l. Patients of any age and sex have been included in the study while any patient who did not undergo surgical intervention due to any reason was excluded from the study. Results: Chemical analysis showed that maximum number of specimen (38.4%) had mixed stones having calcium oxalate and urate as main constituents. The next in order of frequency were pure calcium oxalate stones 28%. In 16% of cases calcium oxalate was mixed with phosphate. Only 8 cases (6.4%) had pure uric acid stones.
