title: Urinary biochemical profile of patients with ureteric calculi in Jodhpur region (north western India).
abstract: Urine chemistry of 42 normal subjects (NS) and 59 ureteric stone formers (SF) from Jodhpur region of Rajasthan, India is presented. Twenty four hour urinary levels of calcium, oxalic acid and uromucoids were significantly higher and levels of magnesium, citric acid and inorganic phosphorus were significantly lower in SF as compared to NS. No significant difference was observed in the uric acid, sodium and potassium levels in the two groups. Significant correlation was observed between calcium and magnesium; calcium and oxalic acid; calcium and citric acid; magnesium and oxalic acid; and oxalic acid and citric acid in NS on the basis of mmol/l but not on the basis of mmol/24 h. Calcium and oxalic acid correlation was uninfluenced by magnesium and citric acid levels. The log of risk factor index (RI) was higher (p less than 0.001) in SF (-1.652) as compared to NS (-2.103). The log of ion activity product (IAP) was also higher (p less than 0.001) in SF (-3.192 X 10(-3)) than in NS (-2.914 X 10(-1)). Based on RI and IAP, a scale has been devised for the prediction of the risk of stone formation and recurrence.
