transurethral radiofrequency ablation
(TRANZ-yoo-REE-thrul RAY-dee-oh-FREE-kwen-see a-BLAY-shun)
A procedure that is used to treat benign prostatic hypertrophy (BPH). An instrument with a small probe that gives off low-level radiofrequency energy is inserted through the urethra into the prostate. The energy from the probe heats nearby prostate tissue and destroys it. This relieves pressure and improves urine flow. Also called transurethral needle ablation and TUNA.
