Transurethral Radiofrequency Ablation

What Transurethral Radiofrequency Ablation Means

Transurethral radiofrequency ablation, often called TUNA or transurethral needle ablation, is a medical procedure used to treat an enlarged prostate, a condition known as benign prostatic hyperplasia (BPH). The prostate is a small gland in men that surrounds the urethra, the tube that carries urine out of the bladder. As men age, the prostate can grow larger and press on the urethra, causing urinary problems.

TUNA uses low-energy radiofrequency waves delivered through two tiny needles inserted into the prostate via the urethra. This energy heats and destroys excess prostate tissue. Over time, the treated tissue shrinks, easing pressure on the urethra and improving urine flow.

Why It Can Matter in Prostate Care

Many men with BPH experience symptoms such as frequent urination, especially at night, difficulty starting urination, weak urine flow, or feeling that the bladder is not fully empty. TUNA offers a less invasive option compared to traditional surgeries like transurethral resection of the prostate (TURP) or open prostatectomy. It is usually done with local anesthesia and does not require a hospital stay.

Some studies have found TUNA to be safe and effective with fewer side effects than other treatments. However, other research has shown that many patients may need additional treatments later. Because of this, some medical guidelines do not recommend TUNA as a first choice for treating BPH. Discussing the risks and benefits with your healthcare provider is important to decide if TUNA is right for you.

What Patients Might See or Hear About TUNA

You might hear the terms transurethral needle ablation, transurethral radiofrequency ablation, or simply TUNA. These all refer to the same procedure. If your doctor mentions TUNA, it is important to ask how it fits your specific health needs and what to expect before, during, and after the procedure.

You may also see this term in medical reports, treatment plans, or educational materials about prostate health. Understanding that TUNA is a treatment option for benign prostate enlargement—not a cancer treatment—is important to avoid confusion.

Common Questions to Ask Your Care Team

If TUNA is mentioned as a possible treatment, consider asking your healthcare provider how it compares to other options, what the risks and benefits are, and what recovery looks like. You might also ask how likely it is that you will need additional treatments later and what symptoms to watch for after the procedure.

Since TUNA is not commonly recommended in some guidelines, it is helpful to understand why your doctor suggests it and whether other treatments might be better suited to your situation.

How to Read the Term in Context

TUNA can appear under different names, such as transurethral needle ablation or transurethral radiofrequency ablation. It’s helpful to compare wording in your medical records or reports. Always ask your care team to explain what the term means in your specific case rather than assuming it applies broadly.

Remember that TUNA is a treatment method, not a diagnosis. It is used to reduce prostate tissue causing urinary symptoms, not to treat prostate cancer.

Safety and Next Steps

This information is educational and does not decide what is safe or appropriate for any individual. If you see the term TUNA in your medical records or hear it from your doctor, the safest next step is to ask your care team what it means for your health and treatment plan. They can explain how it applies to your situation and help you understand your options.
