Transurethral needle ablation (Also called TUNA or transurethral radiofrequency ablation) is a technique that uses low energy radio frequency  delivered through two needles to ablate excess prostate tissue. A cystoscope/catheter deploys the needles toward the obstructing prostate tissue is inserted into the urethra directly through the penis under local anesthetic before the procedure begins. The energy from the probe heats the abnormal prostate tissue without damaging the urethra. The resulting scar tissue later atrophies, reducing the size of the prostate which in turn reduces the constriction of the urethra. It can be done with a local anesthetic on an outpatient basis. It takes about an hour to perform the procedure. It takes about 30 days for the ablated prostate tissue to . Patients should have an annual rectal prostate exam for their doctor to feel the prostate health with a lubricated gloved finger.

A tuna is a saltwater finfish that belongs to the tribe Thunnini, a sub-grouping of the mackerel family (Scombridae) – which together with the tunas, also includes the bonitos, mackerels, and Spanish mackerels. Thunnini comprises fifteen species across five genera, the sizes of which vary greatly, ranging from the bullet tuna (max. length: , weight: ) up to the Atlantic bluefin tuna (max. length: , weight: ). The bluefin averages , and is believed to live for up to 50 years.
