Abstract : Introduction. The 24-hour urine collection test is still the gold standard method for metabolic evaluation in renal stone-forming patients. Recently, some investigators have proposed the spot urine sampling that might be a suitable substitute for 24-hour urine collecting in assessment of recurrent stone-formers. In this study, we evaluate urinary risk factors for calcium stone disease in spot urine and 24-hour urine specimens in recurrent calcium stone formers and non stone formers.Methods. We selected 106 male recurrent stone-formers as cases based on their previous documents versus 109 male healthy volunteers as controls without a history of urolithiasis established by ultrasonography. The age of cases and the control group ranged between 30 to 55 years. Two specimens of 24-hour urine collection in addition to 2 samples of morning spot urine were obtained from all participants. The values of some stone-precipitating solutes as well as some inhibitory factors were measured in all specimens and the results were compared between the 2 groups. Results. In spot urine specimens, the calcium/ creatinine, oxalate/creatinine, citrate/creatinine, uric acid/creatinine, and sodium/potassium ratios were significantly higher among stone formers, while the magnesium/creatinine and potassium/creatinine were significantly lower among stone formers. There were no significant differences in sodium/creatinine and phosphate/creatinine ratios and also, urine specific gravity and PH between two groups. By measuring pearson correlation coefficient, it was demonstrated that there was a significant correlation between the spot urine and 24-hour collection specimens regarding the creatinine-corrected solutes concentrations such as calcium, oxalate, uric acid, phosphate, citrate, sodium, chloride, potassium, and magnesium.Conclusion. One may conclude that morning spot void sample can be a time- and cost-saving alternative for the 24-hour urine collection technique in evaluating recurrent kidney stone-forming patients. Some day-today variations in the results of the spot urine solutes exist that canbe overcome by performing this test more than one time on consecutive days
