Transurethral Needle Ablation (TUNA)


Updated December 21, 2009

Definition: Transurethral needle ablation is a surgical technique in which excess prostate tissue from benign prostatic hyperplasia (BPH) is destroyed through radiofrequency energy.

"Antennas" that project into the tissue from a small fiberoptic camera cause the damage by emitting heat energy.
