Abstract

Introduction: Kidney stones arise from the crystallization and accumulation of certain substances in the kidneys found in urine, such as calcium, oxalate, and uric acid.

Objective: To associate the diagnosed type of kidney stone (Calcium, Uric Acid, Cystine, or Struvite) with the patient's gender at a medical center in Ecuador.

Methods: The study was relational, observational, cross-sectional, retrospective, and analytical in nature. The study sample included 106 patients. The Chi-square test was employed to associate the type of kidney stone with gender.

Results: The predominant type of kidney stone was Calcium at 54.7 % (N=58), followed by Uric Acid at 28.3 % (N=30), and equal figures for Cystine and Struvite at 8.5 % (N=9) each. Among Calcium stones, males were predominant over females (57.4 % vs 51.9 %), as observed in Uric Acid stones (31.5 % vs 25.0 %). However, females were predominant in Cystine (9.6 % vs 7.4 %) and Struvite types (13.5 % vs 3.7 %). The chi-square tests: Pearson's Chi-square (p=0.300), Likelihood Ratio (p=0.281), and Linear-by-Linear Association (p=0.139), reported p-values >0.05 in all cases.

Conclusions: There was no evidence to reject the null hypothesis (H0); therefore, it is concluded that there is no significant association between the different types of diagnosed kidney stones (Calcium, Uric Acid, Cystine, or Struvite) and the gender of patients at the medical center under study in Ecuador.
