Hypercalciuria and hyperoxaluria are the two major risk factors in urolithiasis. In India, the prevalence of stone disease is much higher in many areas, affecting about 6 subjects in 1000 population in the Udaipur region (1), Pendse et al. (2, 3) observed hypercalciuria and hyperoxaluria as predominant factors. Hypercalciuria is the most-common biochemical abnormality in patients with calcium urolithiasis (4). More recently, the role of oxalate in urolithiasis has been stressed and is thought to be more significant than hypercalciuria (5). In the present paper, we have studied calcium and oxalate excretion in normal subjects (NS) and stone formers (SF) in the Udaipur region.
