Comparing Flexible and Semi-Rigid Ureteroscopy for Treating Upper Ureteric Stones Smaller Than 2 cm

What this Trial Is About

Researchers are evaluating the effectiveness, safety, success rates, operation times, and cost differences between flexible ureteroscopy and semirigid ureteroscopy for treating upper ureteric stones smaller than 2 cm. The study focuses on determining which patients with upper third ureteric stones can be treated with semirigid ureteroscopy and which require flexible ureteroscopy, considering factors such as stone size, stone impaction, ureter anatomy, surgeon experience, anesthesia, and ureteric dilation. Participants receive either flexible ureteroscopy or semirigid ureteroscopy, both minimally invasive procedures to remove stones from the upper ureter. Flexible ureteroscopy allows more maneuverability and access to difficult stone locations, while semirigid ureteroscopy is typically faster and less costly but may be less effective for complex cases. Both use holmium laser lithotripsy to break the stones. Treatment choice depends on stone location, size, surgeon preference, and equipment availability. During the study, participants will be monitored for stone-free status at 3 months post-procedure, along with assessments of safety, operation time, and cost-effectiveness. Researchers will track operative success and complications to compare outcomes between the two methods. The study involves regular follow-ups to evaluate treatment success and ensure patient safety throughout the trial period.
