Brief summary

This is a retrospective, multi-center collaboration to assess real-world outcomes of a novel steerable aspiration system, the CVAC® System (CVAC), and flexible and navigable suction ureteral access sheath (FANS) for the treatment of urinary stones.

Detailed description

The objective of this study is observation of the safety and efficacy of subjects who underwent SURE procedure using the CVAC System or FANS for the removal of kidney stones in candidates for URS with laser lithotripsy. Efficacy will be observed by reviewing stone free status on standard of care post-procedure imaging. Safety will be observed by reviewing procedural information and if subjects had urologic events leading to Emergency Department (ED) visits, hospitalization, or retreatment.

Interventions

The CVAC Aspiration System is a sterile, single use, steerable ureteral catheter system with integrated vision, irrigation and aspiration for the treatment and removal of urinary stones (kidney stones, fragments, and dust).

FANS is designed to incorporate suction to facilitate stone fragment removal through its lumen and is used with a separate ureteroscope. FANS is fitted with a Y connector with a pressure control vent and connects to a standard vacuum device. A separate ureteroscope provides direct visualization and irrigation and a separate specimen collector captures stone debris.
