Identifying recurrent stone formers with machine learning: A single-centre observational study. [PDF]
BJUI CompassAbstract Objectives Kidney stones affect 12% of the population over their lifetime. Recurrent kidney stones lead to repeated interventions and excessive healthcare costs. Despite progress in imaging and metabolic evaluations, models to accurately identify patients at high risk are missing.
