Sponsor's own description
This prospective observational study aims to investigate whether preoperative urine culture results are associated with the incidence of postoperative fever in patients undergoing flexible and navigable suction-assisted retrograde intrarenal surgery (FANS-RIRS). In current clinical practice at our center, urine routine analysis and urine culture are both performed before admission. For patients without significant pyuria or other clinical signs of active infection, surgery is performed without waiting for the final urine culture results, and standard perioperative antibiotic prophylaxis is administered. Based on the final reported preoperative urine culture results, enrolled patients will be classified into different groups, and postoperative febrile outcomes will be prospectively recorded and compared. The primary outcome is the occurrence of postoperative fever within the early postoperative period. Relevant demographic, clinical, stone-related, laboratory, and perioperative variables will also be collected to explore potential risk factors for postoperative fever. The study is designed to evaluate the predictive value of preoperative urine culture in a real-world FANS-RIRS pathway and to provide evidence for perioperative infectious risk stratification and management in patients undergoing endourological stone surgery.
