Predicting Risk Factors Affecting the Efficacy of Flexible Ureteral Holmium Laser Lithotripsy and Extracorporeal Shock Wave Lithotripsy for Ureteral Calculi Based on Decision Tree Model.

Aim: To evaluate the efficacy of flexible ureteroscopic lithotripsy (FURL) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi based on decision tree model.

Methods: A total of 600 patients with ureteral calculi, including 289 treated with FURL and 311 cases with ESWL in Anqing Municipal Hospital from June 2021 to August 2023, were selected as study subjects. Perioperative indicators and stone clearance rate of the two groups were compared, and the preoperative and postoperative (24 and 72 hours) changes of serum creatinine, cystatin C (Cys-C) and microalbumin were observed.
