Study of age and gender characteristics of patients treated for kidney stones in relation to disease risk at The First State Central Hospital

Abstract

Background: Studies on the risk of kidney stone disease by age and gender show that the prevalence varies by countries and regions, particularly influenced by the conutry development, population diet, etc. In our country, research on kidney stones has been scarce over the past two decades. Aim: To study the age and gender characteristics of patients undergoing surgical treatment for kidney stones. Materials and Methods: Data from a total of 551 individuals who underwent surgical treatment at the Urology Department of the First State Central Hospital over a six-month period (01.01.2024-06.01.2024) were analyzed. The age and gender characteristics of patients diagnosed with kidney stones were studied, and logistic regression was used to test the true probabilities. Statistical analysis was performed using SPSS 27 software, with a significance level set at 0.05. Results: Kidney stones were present in 12.5% of surgical patients (n=69), while other urological diseases accounted for 87.5% (n=482). The mean age of patients with kidney stones was 46.46±12.6 years, which is relatively younger compared to patients with other urological surgical conditions (mean age=55.77, SD=16.174). Regarding the prevalence of kidney stones by gender, females accounted for 56.5% and males 43.5%. Considering the gender distribution of all patients receiving urological surgical care, females constituted 19.9% compared to 8.5% for males, nearly double the incidence. According to logistic regression analysis, women had a 1.5-fold higher risk of developing kidney stones compared to men (OR=1.5, 95% CI: 1.5–4.2, p<0.01). The highest prevalence was observed in the 36–55-year age group, while individuals aged over 55 years had a significantly lower risk (OR=0.19, 95% CI: 0.10–0.39, p<0.001). Conclusion: Kidney stones were identified in 12.5% of individuals who underwent urological surgery. The majority of hospitalized patients with kidney stones were aged 36–55 years, and women comprised 56.5% of these cases.
