To describe the risk of urinary tract infections (UTIs) in patients with kidney stone disease (KSD) and compare the risk based on stone composition, including a secondary aim to analyze differences in UTI risk by stone type.
Key Findings:
Patients with KSD had a significantly increased risk of UTI (HR 5.73; 95% CI 4.55–7.21, p < 0.001), indicating a strong association.
The risk remained significant after adjusting for diabetes (HR 5.76; 95% CI 4.50–7.36, p < 0.001), emphasizing the robustness of the findings.
Calcium oxalate stone formers had the highest risk of UTI (HR 6.36; 95% CI 4.82–8.29), highlighting a critical area for clinical focus.
Interpretation:
The study indicates a strong association between KSD and increased UTI risk, particularly in patients with calcium oxalate stones, suggesting a potential area for clinical intervention, such as targeted monitoring and preventive strategies.
Limitations:
Retrospective design may introduce biases in data collection, potentially affecting the reliability of UTI incidence rates.
Causality between UTI and stone formation remains unclear, necessitating further research to establish direct links.
Conclusion:
Kidney stone formers are at a significantly higher risk for developing UTIs, particularly those with calcium oxalate stones, underscoring the urgent need for effective monitoring and management strategies in this population.
Kidney cancer is a growing global health problem, and both clinicians and policymakers need to prepare for a steep rise in the number of cases,” said Alexander Kutikov, MD, FACS, Chair of the Department of Urology at Fox Chase Cancer Center, and senior author of a landmark international study published in European Urology, which demonstrates that if current trends continue, kidney cancer cases could double by 2050
