[Recurrence-free and recurrent urolithiasis: metabolic differences].
Biochemical tests by 12 metabolic blood and urine indices reflecting the condition of renal function and metabolism of urolithogenic substances were made in the course of 1-6 year follow-up of 35 and 79 patients (46 females and 68 males aged 18-65 years) with recurrence-free and recurrent urolithiasis, respectively. The risk of recurrence for uric acid urolithiasis in serum concentration of urea 5.67 +/- 0.14 mmol/l and creatinine 0.090 +/- 0.008 mmol/l, in hyperuricemia and hyperuricuria was associated with elevation of renal excretion of total calcium to 5.88 +/- 0.49 mmol/day and ratio of daily renal excretion of sodium to renal daily excretion of potassium to 3.28 +/- 0.08; for calcium-oxalate lithiasis--with a rise in serum concentration of uric acid to 0.310 +/- 0.042 mmol/l and sodium to 114 +/- 0.8 mmol/l in hypercalciuria and hyperuricuria.
