Antibiotic prophylaxis in VUR

Article DOIhttps://doi.org/10.1038/s41598-025-92847-3
ObjectiveTo predict which patients with vesicoureteral reflux are most likely to benefit from continuous antibiotic prophylaxis
AI ApproachLogistic regression, random forest, SVM, gradient boosting, CNN
Data Source(s)Two-centre institutional series (225 patients)
Model InputGender, age at diagnosis, uni- or bilaterality of VUR, DMSA differential renal function, VUR grade, dilating or non-dilating reflux in ultrasonography, presence of fUTI, prenatal hydronephrosis, ureteral anomaly, bladder dysfunction, failure to thrive, renal scarring
Model OutcomeFebrile UTI or renal scarring
VUR persistence
Model MetricsPredict fUTI and/or renal scarring:
AUC 0.78, accuracy 75%, sensitivity 0.64

Predict VUR persistence: Random forest:
AUC 0.72, accuracy 72%, sensitivity 0.70
Model UsabilityNo available code or dataset, no accessible predictive tool.

AI = Artificial intelligence, VUR = Vesicoureteral Reflux, CNN = Convolutional Neural Network, SVM = Support Vector Machines
