Analysis of Risk Factors and Construction of a Prediction Model for Preoperative Concurrent Pathogenic Pyuria in Patients With Ureteral Calculi

This study not only confirms that female gender, bilateral UC, stone size, and hydronephrosis size are independent risk factors for preoperative pyuria in patients with UC, but also further identifies that female gender, comorbid diabetes mellitus, and hydronephrosis size > 40 mm are independent risk factors for preoperative concurrent pathogenic pyuria in such patients. The prediction model constructed accordingly can effectively assess the risk of preoperative concurrent pathogenic pyuria in female patients with UC, providing a practical reference basis for clinicians to implement early preoperative intervention in such patients.
