Kidney stone disease (KSD) affects around 10% of the global population, associated with severe pain, recurrent hospitalizations, and potential long-term kidney complications. In Brazil, the management of these cases within the Public Health System (SUS) still lacks detailed analyses regarding prevalence, costs, and outcomes, making it difficult to identify regional disparities. This study aims to analyze hospitalizations, interventions, costs, and outcomes related to KSD in SUS between 2015 and 2025, highlighting trends and regional differences.
This is a retrospective quantitative study using data from the Brazilian Public Health System's Hospital Information System (SIH/SUS) from 2015 to 2025. Absolute numbers of hospitalizations, interventions, costs, length of stay, and deaths related to renal calculi were analyzed. Data were obtained through the DATASUS platform, with the analysis focusing on total counts, regional distribution, monthly trends, and associated healthcare costs. All data are publicly available, ensuring patient confidentiality.
The analysis of hospitalizations across Brazil’s regions reveals disparities in healthcare utilization, costs, and outcomes regarding KSD. The North region reported the fewest hospitalizations (202) with a total cost of approximately US$19,570 and no deaths, while the Northeast had 5,816 hospitalizations totaling around US$449,800, with 27 deaths and a mean cost per hospitalization of US$85.68 over an average stay of 5.67 days. The Southeast and Central-West regions had the highest hospitalization numbers, 11,549 and 11,265 respectively, with total costs of US$971,800 and US$984,800; their mean costs per hospitalization were US$85.19 and US$88.39, with 31 and 18 deaths and average lengths of stay of 4.63 and 4.35 days. The South region recorded the highest mean cost per hospitalization (US$99.50) despite a lower number of hospitalizations (4,291) and a short average stay of 3.3 days, with six deaths.
The analysis highlights significant regional disparities in healthcare utilization across Brazi for KSD treatment. While the North reported the lowest number of hospitalizations and no deaths, the Southeast and Central-West concentrated the highest volumes of admissions and total costs, though with relatively short average lengths of stay. In contrast, the Northeast showed a considerable number of deaths associated with hospitalizations. Meanwhile, the South presented fewer admissions and shorter stays but registered the highest mean cost per patient. These findings emphasize the need for region-specific strategies to optimize resources, reduce inequalities, and improve health outcomes.
