BLOOMINGTON, Ind.--(BUSINESS WIRE)--Following its first year in use, the Cook Medical Resonance® Metallic Ureteral Stent has proven to successfully relieve extrinsic ureteral compression, a painful and often debilitating side effect of cancer. In addition, the Resonance Stent can remain in the patient for up to 12 months, resulting in a reduction of the costs accrued by both patients and their healthcare facilities stemming from the numerous interventions needed with alternative care. Additionally, long-term cancer patients may have health insurance policies that cap reimbursement for repeated procedures. As a result, charges for repeated stent changes may go unpaid.
