Protocol summary

Study aim
Comparison of success rate and complications of transureteral lithotripsy in uncomplicated ureteral stones with or without safety guide wire
Design
Two arm parallel group randomised trial with blinded postoperative care and outcome assessment, sample size 348
Settings and conduct
After splitting the patients randomly into groups A and B. in group A, ureteroscopy is done after the ureteral guide wire is inserted, the guide wire remains in the system, and the lithotripsy is performed in the presence of the guide wire. In group B patients, ureteroscopy is performed on the guide wire and after reaching the stone, the guide wire is removed lithotripsy is performed. After breaking the stone into pieces that are disposable to the size of a lithoclast probe, the operation ends. In the event of possible injury to the ureter or edema of the tissue or suspicion to a large number of ureteral stone fragments, a Double-J stent is inserted and reported and recorded. All patents are fallowed for one month after surgery and any complications such as pain, fever and peritonitis is recorded. At the end all data will be given to statistics specialist for analysis
Participants/Inclusion and exclusion criteria
All male and female patients; need to spectroscopy or TUL; aged 20 years or above; willing to participate in this clinical trial
Intervention groups
The first group: before endoscopic ureteral lithotripsy, a safety wire is inserted into the ureter and then lithotripsy is performed. The second group: endoscopic ureteral lithotripsy without embedded safety guide wire is performed.
Main outcome variables
Ureteral injury (ureteral perforation or rupture); complete stone clearance; Need for ureteral stent placement; Duration of operation; Delayed ureteral stenosis

Intervention groups

1

Description
Intervention group: not using the safety guide wire before trans ureteral lithotripsy. In this group the Lithotripsy will be started as soon as the stone is spotted in endoscopy and no more manipulation is done
Category
Treatment - Surgery

2

Description
Control group: using safety guide wire. In this group, as soon as the stone is reached, the safety weir is secured from the side of the stone through the ureter into the pelvis, then the endoscope is removed, and the ureteroscopy is performed again from the side of the wire to the location of the stone, and then the lithotripsy is performed.
