The efficacy of Ho: YAG and TFL combined with semirigid ureteroscopic treatment of proximal ureteral stones will be compared.

Known anatomical abnormalities (such as urinary diversion or ureteral stenosis);
Parallel
Thulium Fiber laser (TFL) lithotripsy
DevicePatients with proximal ureteral stones undergoing ureteroscopic lithotripsy using thulium laser lithotripsy.
Ho: YAG lithotripsy
DeviceHo:YAG laser lithotripsy was used in patients with proximal ureteral stones undergoing ureteroscopic lithotripsy.
Stone-free rate (SFR)
Stone-free rate (SFR) after single-session laser lithotripsy using a semirigid ureteroscope without an auxiliary procedure assessed by CT/X-ray at 2-4 weeks follow-up after laser lithotripsy.
Operative time
the time of laser lithotripsy
Intraoperative complications
bleeding, ureteral perforation, ureteral wall injury, or intraoperative adverse events leading to termination of surgery
Postoperative complications
Occurrence of postoperative complications
Additional procedures
If semi-rigid ureteroscopy combined with laser lithotripsy fails, it is converted to flexible ureteroscopy, PCNL, laparoscopic lithotomy. In addition, ESWL treatment is performed before the double-J stent is removed after surgery.lithotripsy, and postoperative ESWL treatment before removal of the ureteral stents, among others.
