Slightly weak antioxidant status and raised oxidative stress is suspected in renal disorders including renal stone disease. Hyper–oxaluria and hypocitraturia are also reported as risk factors in renal stone disease. A possible collusion of oxidative stress, hyper–oxaluria and hypo–citraturia in etiopathogenesis of nephrolithiasis has been suggested.

Objective– To examine whether imbalanced redox and hyperoxaluria, possess a risk in nephrolithiasis
