Transurethral Needle Ablation, or TUNA is an effective, minimally invasive treatment for the symptoms of BPH – Benign Prostatic Hyperplasia. This is also the technical and generic term for Prostiva® RF Therapy. Because of the safety and effectiveness of TUNA, many patients and urologists opt for an RF treatment rather than chronic medication, which can cause significant side effects.1 TUNA is covered by Medicare as well as most private insurance plans.
