AI-POWERED UROSEPSIS PREDICTION
Enhancing Post-Operative Patient Safety
This study develops and validates a robust machine-learning model (XGBoost) for predicting urosepsis after ureteroscopic lithotripsy. By leveraging key clinical variables, the model achieves high accuracy (AUC 0.98), enabling early identification of high-risk patients and supporting precise preventive strategies.

Superior Predictive Accuracy
The XGBoost model demonstrated exceptional performance across training, internal test, and external validation sets. With an AUC of 0.98 (95% CI: 0.97–1.00) in internal testing and 0.99 (95% CI: 0.97–1.00) in external validation, it significantly outperformed SVM, LR, and RF models. This high accuracy ensures reliable identification of patients at risk of postoperative urosepsis, facilitating proactive intervention.

Six Core Predictors Identified
Key Predictive Factors Identified
The SHAP method revealed that procalcitonin, albumin, degree of hydronephrosis, 5-item frailty score, maximum stone diameter, and urinary tract infection were the top six key predictors. These variables offer a comprehensive view of patient functional status, stone characteristics, and immune indicators, providing a scientific basis for early identification and targeted prevention strategies.
Early Identification & Intervention
Scenario: A 65-year-old patient undergoing ureteroscopic lithotripsy for a 12mm stone presents with elevated procalcitonin levels and a 5-item frailty score of 2 pre-surgery. The AI model predicts a high risk of urosepsis.
Outcome: Based on the AI model's prediction, enhanced prophylactic antibiotics and close post-operative monitoring were initiated. Despite initially developing a low-grade fever, prompt targeted treatment prevented progression to severe sepsis, reducing hospital stay by 3 days and avoiding intensive care. This demonstrates how the model enables proactive, personalized management to mitigate severe complications and improve patient outcomes significantly.
Quantifiable Decision-Making Tool
The developed model and its associated web application provide a quantifiable decision-making tool for healthcare professionals. By inputting patient-specific feature values, clinicians can obtain a probability of urosepsis, aiding in risk stratification and precise management of postoperative complications, thereby reducing patient burden and improving overall prognosis.
