Transurethral needle ablation of the prostate (TUNA) involves using high-frequency radio waves to produce heat, resulting in a similar process of thermal injury to the prostate as previously described. A specially designed transurethral device with needles is used to deliver the energy.

TUNA can be performed under local anesthesia, allowing the patient to go home the same day. Similar to microwave treatment, radiofrequency treatment is quite popular, and a number of urologists have experience with its use. Radiofrequency treatment appears to reliably result in significant relief of symptoms and better urine flow, although not quite to the extent achieved with TURP. The 2018 AUA guideline update does not recommend the use of TUNA for the treatment of BPH. [1]
