Biochemical aberration in patients with upper tract Urolithiasis.
Professional Med J Jan ;3(4):289-93.

The present study was carried out at Lahore to demonstrate the different biochemical risk factors in patients with upper urinary tract stone disease. A total of 256 consecutive patients with upper tract stone disease were included. Sampling was done for serum calcium and uric acid and 24 hours urinary calcium, uric acid, urinary volume and urinary pH. We conclude that hyperuricoseuria and low urinary pH are the main biochemical risk factors prevailing in the region.
