Abstract

Urinary abnormalities were evaluated in 100 renal stone patients with first episode of renal stone having age 22 to 45 years from both sex and compared to 100 normal healthy control group having same age group from both sex. Twenty-four hours urinary oxalate, calcium, uric acid, sodium, magnesium, phosphorus and citrate were estimated. The urinary pH was also determined. In stone formers urinary oxalate, calcium, sodium and uric acid excretions were significantly higher when compared with control group. Whereas citrate, phosphate and magnesium excretion were significantly lower in stone formers when compared with control.The pH of urine in stone formers was lower than the controls. High dietary intake of purine rich diet causes elevated excretion of uric acid, which leads to calcium oxalate crystal formation and precipitation. Other risk factors such as urinary oxalate, calcium also related to formation of renal calculi.Hypocitraturia is the main cause of renal calculi along with hypomagnesiuria and hypophosphaturia in the patient of Marathwada region. On the basis of urinary abnormalities further stone formation in the patient can be prevented by dietary modifications.
