Abstract

Introduction: Urinary stones, also known as urolithiasis, is a disease caused by the presence of stones or calculi inside the kidneys or urinary tract (ureters, bladder). Kidney stones are made up of normal substances in the urine, but for different reasons they concentrate and solidified as fragments of various sizes. It is a common affection in more than 10% of the population in their middle age and is more common in men. Urinary stones are more prevalent in people with sedentary habits or those with high exposure to heat and dehydration. The analysis by dissolving kidney stones allows us to evaluate its chemical composition and thus take appropriate measures to prevent recurrence.

Objective: The main objective was to analyze the chemical composition of urinary calculi in patients from a private clinic and find out the frequency of its occurrence between genders and age groups.

Methodology: Descriptive, transversal study. Urinary calculi analysis of 80 patients performed. Gender and age data recorded.

Results: Out of 80 samples analyzed, 75 urinary calculi composition was calcium oxalate (93.75%), 4 of uric acid (5%), 1 cystine (1.25%) and none of struvite (0%) found. The groups were composed of 62 males (77.5%) and 18 female (22.5%) with an age range between 18 and 80 years and an average age of 41.4 years.

Conclusion: The baste majority of calculi analyzed in the study were composed of calcium oxalate, which is consistent with statistics from NHANES where approximately 80% of calculi are composed of calcium oxalate. In this study 93.75% of calculi examined were composed of calcium oxalate.  Seventy-six (76%) of patients with calcium oxalate calculi are male with a median age of 46.4 years.  Uric acid calculi were present in 5% and 100% of those found in males. Cystine calculi found had a prevalence of 1.25% with 100% in males and the struvite calculi were not found.  It was concluded that male patients have a higher prevalence information of urinary calculi and oxalate ones predominate
