ABSTRACT

Introduction: The association of urinary sodium excretion and the urine volume may be an element to be considered for the prescription of treatment in patients with urinary lithiasis.
Objective: To determine the possible association of urinary sodium excretion and urine volume in Cuban adult lithiatic patients.
Methods: A cross-sectional and descriptive study and metabolic study were conducted at the Institute of Nephrology from January 2009 through December 2012. The variables age, sex, weight, and height were registered, serum creatinine and urinar ysodium were estimated and urine volumen was measured. Data were processed with the SPSS 18.0 software. The averages were compared through the t-test and ANOVA. Pearson´s linear correlation coefficient and the simple linear regression wereal soused in thestudy.
Results: Average daily urine volume in males was higher than that of females by 105 mL approximately. The urinary volume mean increased from 1267.8 mL in patients with urinary sodium excretion below 100 mEq/day to 2927.7 mL in subjects with urinary sodium excretion over 400 mEq/day (p= 0.00). Pearson´s linear correlation coefficient was 0.75, which indicated a great direct association among the variables.
Conclusions: In urolithiatic patients, there is direct predictable association of the urinary volume and urinary sodium excretion that should be taken into consideration when making dietary recommendations for treatment.
