The SURE Kidney Stone Procedure by Calyxo
Updated: Oct 2
The SURE (steerable ureteroscopic renal evacuation) procedure by Calyxo is used during ureteroscopy for kidney stones. It uses the CVAC Aspiration System, a steerable catheter with irrigation and suction, to help remove stone fragments after the stone has been broken up with a laser.
Key Features of the SURE Procedure:
Visualization: The ureteroscope allows the surgeon to see inside the kidney directly. The CVAC catheter is used to suction out stone fragments and dust; the stone itself is broken up with a laser.
Evidence: In a randomized trial sponsored by the manufacturer (ASPIRE, 101 patients analyzed), the share of patients with no residual fragments at 30 days was similar with SURE and standard ureteroscopy (48% vs 49%), and the measured residual stone volume was lower with SURE. Longer-term and independent data are limited, and results vary by patient and stone.
Safety: In the same trial, safety was reported as comparable to standard ureteroscopy. As with any ureteroscopy, risks include infection, bleeding, injury to the ureter, and the possible need for a temporary stent or additional procedures.
Recovery: SURE is performed through the urinary tract without a skin incision. Discomfort and recovery vary by patient, and a temporary ureteral stent may be needed. Your urologist can discuss whether this approach is appropriate for your stones.
