Keywords:Urinary Stones. Calcium Oxalate. Kidney Calculi. Urinary Bladder Calculi. Ureteral Calculi. Uric Acid. Oxalates. Magnesium Compounds. Recurrence.
Aim: To find out the constituents of the urinary stones, so that preventive measures would be taken against recurrence. Patients and methods: A total No. of 200 consecutive patients with upper urinary tract calculi, that were operated in the urology and general surgical wards of Sh. Zayed Hospital Rahim Yar Khan were included in the study. In addition to Rahim Yar Khan the patients also came from adjacent districts of Sindh and Baluchistan. Qualitative Chemical analysis was carried out using Merchognost (Germany) urinary calculi analysis kit. All the tests were performed according to the instruction of manufacturers of the kit. Results: Stone samples were collected from 200 patients, out of these 138 (69%) were male and 62 (31%) of patients were female with male to female ratio 2.2:1 age range was between 9-72 years. Results of stone analysis indicate that calcium oxalate is the most common ingredient found in 100% of the stone samples. In 83% of patients it was found mixed with other varieties of stones while in 17% samples it was seen in pure form. Uric acid was the second most common ingredient seen in 73% of patients mixe d with calcium oxalate and magnesium ammonium phosphate but it was not found as pure form. Magnesium Ammonium phosphate found in 13% of stones samples in mixed form only, not as isolated stone.
