Clinical Trial: Safety and Efficacy of Traditional Versus Suction Ureteral Access Sheath in Retrograde Intra-Renal Stone Surgery

U.S., Dec. 17 -- ClinicalTrials.gov registry received information related to the study (NCT07286071) titled 'Safety and Efficacy of Traditional Versus Suction Ureteral Access Sheath in Retrograde Intra-Renal Stone Surgery' on Dec. 03.

Brief Summary: This study compares two techniques used during RIRS for the treatment of kidney stones measuring up to 20 mm. During RIRS, surgeons often use a device called a UAS to help pass instruments into the urinary system and to assist with the removal of stone fragments. A traditional UAS allows irrigation fluid and small fragments to flow out passively. A newer type, known as a suction UAS, applies controlled negative pressure to help clear stone fragments more effectively and may reduce pressure insi...
