Resumen

Introduction: Urolithiasis is a common disease that has become a chronic illness with great impact on the quality of life of the sufferer. The aim of this study was to describe the epidemiological characteristics of patients hospitalized for urolithiasis in Peru. Material and methods: A cross-sectional analysis of data from 9 hospitals between 2017–2021 was performed, including patients of all ages with diagnoses of renal calculi, ureter, lower urinary calculi and renal colic. Urological attendances were analyzed by frequencies, age and sex, using the Chi-square test to test hypotheses. Results: 34,928 patients were included, predominantly female (ratio 4:6). Renal and ureter calculi was the most frequent diagnosis (76.1%), followed by renal colic (20.1%). In women, renal calculi and ureter (55.2%) and renal colic (54.4%) were more prevalent. In men over 60 years of age, lower urinary calculi were more prevalent (343 cases; 20.37%) than in women (145 cases; 8.61%), with significant differences (p<0.001). In the 30–59 years age group with renal colic, women were more prevalent (3131 cases; 35.7%) than men (2938 cases; 33.5%), also statistically significant (p<0.001). Conclusion: This study highlights the high burden of urolithiasis in women and the variability in patterns according to age and type of diagnosis. The findings provide valuable information on the urological epidemiology in Peru, useful for optimizing care and prevention of this disease in different regions of the country. © (2026), (Sociedad Mexicana de Urologia.
