Kidney diseases are a significant burden on public health, contributing to high morbidity and mortality rates. The contribution of such diseases to hospitalization and patient outcomes in Brazil has, despite increasing rates of chronic kidney disease and subsequent complications, yet to be studied. Understanding hospitalization rates and mortality due to nephrologic diseases is critical to guide healthcare policy, resource allocation, and preventive measures. This work aims to provide a retrospective hospitalization and mortality study of nephrological disease in Brazil, providing an epidemiological trend which can be used to determine potential areas for intervention.
This is a retrospective quantitative study using data from the Brazilian Public Health System's Hospital Information System (SIH/SUS) from August 2024 to July 2025. Absolute numbers of hospitalizations and deaths from nephrological diseases, including kidney failure, tubulointerstitial kidney diseases, and urolithiasis, were analyzed. Data were obtained through the DATASUS platform, with the analysis focusing on total counts, main causes, monthly variation, and regional distribution of cases.
From August 2024 to July 2025, a total of 387,172 hospitalizations and 20,233 deaths from kidney diseases were recorded, totaling 407,405 cases during the period. The main causes of mortality and hospitalization include kidney failure (159,201 hospitalizations), tubulointerstitial kidney diseases (60,002 hospitalizations) and urolithiasis (153,116 hospitalizations). The analysis of the period does not show a clear seasonal pattern, with the number of hospitalizations ranging from 31,137 in December 2024 to 33,926 in March 2025, while deaths fluctuated between 1,526 in December 2024 and 1,820 in July 2025. The Southeast Region recorded the highest number of deaths from kidney failure, with 8,246 fatalities.
This study highlights the significant burden of kidney diseases in Brazil between August 2024 and July 2025, with more than 400,000 recorded cases, over 20,000 of which resulted in death. Kidney failure, tubulointerstitial diseases, and urolithiasis were identified as the main causes of hospitalizations and mortality, underscoring their epidemiological relevance and impact on the healthcare system. The absence of a clear seasonal pattern indicates that these conditions maintain relatively constant incidence and severity throughout the year, requiring continuous surveillance and permanent care strategies. Furthermore, the concentration of deaths from kidney failure in the Southeast may reflect both population density and potential regional inequalities in access to early diagnosis and specialized treatment. These findings reinforce the need for public health policies aimed at prevention, screening, and adequate management of kidney diseases, with the goal of reducing hospitalizations and associated mortality.
