Use of a Ureteral Access Sheath During Ureteroscopy and Its Effect on Stone Free Rate

Urinary Calculi Clinical Trial

Official title:
A Prospective Randomized Controlled Clinical Trial of the Use of a Ureteral Access Sheath During Ureteroscopy and Its Effect on Stone Free Rate

Clinical Trial Summary

Patients with upper ureteral or renal stones will be randomized to undergoing ureteroscopy with or without a ureteral access sheath. The sheath is designed to facilitate ureteroscope insertion and re-insertion, thus allowing fragments to be basketed out. Stone free rates at 3 months will be determined between the two groups.

The investigators hypothesize that the use of the ureteral access sheath with ureteroscopy will result in improved stone free rates at 3 months compared to ureteroscopy without use of a sheath.
