Transurethral radiofrequency thermotherapy of the prostate is a method of treating benign prostatic hypertrophy (BPH). This procedure delivers selective thermal energy to the prostate while preserving the urethra and adjacent structures.
This procedure is also known as transurethral needle ablation of the prostate (TUNA).
The procedure uses radio waves to heat and destroy the part of the prostate that's blocking urine flow. A cystoscope is passed into the urethra and needles are placed in the prostate gland under visual guidance. Radio waves pass through the needles and heat the prostate and destroy the blockage.
