Transurethral Needle Ablation

What Transurethral Needle Ablation Means

Transurethral needle ablation (TUNA) is a medical procedure used to treat an enlarged prostate, a condition called benign prostatic hyperplasia (BPH). The prostate is a small gland in men that surrounds the tube (urethra) carrying urine out of the bladder. When the prostate grows larger with age, it can press on the urethra and cause 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, which then shrinks over time, easing pressure on the urethra and improving urine flow.

Why It Can Matter in Prostate Care

Many men experience symptoms from an enlarged prostate, such as needing to urinate frequently, 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 suggest it can improve symptoms with fewer side effects, but other research notes that some men may need further treatment later. Because of this, some medical guidelines do not recommend TUNA as a first choice for treating BPH.

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 about 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

Because TUNA can appear under different names, 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 relieve symptoms caused by an enlarged prostate, not to treat prostate cancer.

Safety and Next Steps

This information is meant to help you understand what transurethral needle ablation is and how it might relate to your prostate health. It does not replace personalized medical advice. If you see this term in your health records or hear it from your doctor, the best next step is to ask your healthcare team to explain what it means for you, including whether it is a recommended treatment and what you can expect. Open communication with your care team will help you make informed decisions about managing prostate symptoms.
