Perfil epidemiológico de las hospitalizaciones por urolitiasis en el Estado de Yucatán, México

Objective: To describe the epidemiologic characteristics of patients hospitalized due to urolithiasis in the State of Yucatan, Mexico, compared with official state and national references. Methodological design: A retrospective, descriptive, observational, cross-sectional study was conducted. It included the hospitalizations due to urolithiasis in the public health sector, within the time frame of 2014 to 2016 in Yucatan, comparing them with the official state and national references through hypothesis contrast tests for independent samples adjusted to population size. Results: A total of 1078 hospitalizations due to urolithiasis in Yucatan were registered and 52.8% corresponded to male patients. The mean age at hospitalization was significantly lower in the female patients at both the state and national levels. The prevalence of obesity in the hospitalized patients was 33.33, which was not statistically different from that reported by the state. The number of hospitalizations of patients residing in the capital was significantly lower than expected (31.9 versus 52.9). Limitations: The present study was restricted to public health sector hospitalization data, and therefore, private sector registers were excluded. Originality and value: The present analysis is the first epidemiologic study to compare and evaluate the epidemiologic factors of the registered cases of hospitalizations due to urolithiasis in the State of Yucatan. Conclusions: There was a higher number of hospitalizations in the State of Yucatan than those registered nationally, resulting in the highest hospitalization rate in the country. Prevalence was slightly higher in men, whereas age was lower in women. The prevalence of obesity and the number of hospitalized patients of Mayan ancestry did not differ from the state registers. The number of hospitalized patients residing in the capital was lower than expected.
