Summary

To compare the efficacy, safety, success rate, operative time, and cost-effectiveness of flexible ureteroscopy versus semirigid ureteroscopy in the management of upper ureteric stones smaller than 2 cm.

The investigators' main concern in this study is Upper third ureteric stones to determine which cases can be treated with Semi-Rigid Ureteroscopy, and which one needs flexible ureteroscopy. This depends on several factors:

1. Division of the upper third of the ureter
2. Stone size
3. Stone impaction
4. Surgeon experience
5. Anesthesia
6. Ureteric dilatation above the stone
7. Mini endoscopy
