Transurethral Needle Ablation (TUNA) offers a minimally invasive approach for addressing symptoms of benign prostatic hyperplasia (BPH). This procedure aims to alleviate urinary discomfort and difficulties from an enlarged prostate gland. It provides an option for individuals seeking relief without extensive surgical interventions.
What is Transurethral Needle Ablation?
Transurethral Needle Ablation (TUNA) uses controlled radiofrequency (RF) energy to reduce an enlarged prostate gland. This energy generates heat within specific prostate tissue areas, causing thermal necrosis that destroys excess tissue obstructing urine flow.
TUNA treats benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland surrounding the urethra. As the prostate grows, it can compress the urethra, leading to urinary symptoms like frequent urination, urgency, and a weak stream.
How the Procedure Works
The TUNA procedure is performed on an outpatient basis, allowing patients to return home the same day. It uses local anesthesia, sometimes with mild sedation. A specialized catheter is advanced through the urethra to the prostate gland.
The catheter contains tiny needles deployed into the prostatic tissue. Radiofrequency energy is delivered through these needles, generating precise heat in targeted areas. An integrated cooling system protects the urethral lining from thermal damage. Over several weeks to months, the heated tissue is reabsorbed by the body, reducing prostate volume and improving urine flow.
Recovery and Potential Side Effects
Following TUNA, recovery is swift. Patients may experience temporary urinary symptoms as the treated tissue heals and shrinks. These can include increased urinary frequency, urgency, mild discomfort during urination, or a small amount of blood in the urine. These symptoms subside within a few days to several weeks.
A temporary urinary catheter may be required after the procedure to ensure proper urine drainage while prostate swelling subsides. Full therapeutic effects, such as improved urinary symptoms, may take several weeks to a few months to become noticeable as the treated tissue is reabsorbed.
Considering TUNA as a Treatment Option
Transurethral Needle Ablation can be a suitable treatment option for men experiencing moderate to severe BPH symptoms. It is often considered by individuals who may not be candidates for more invasive surgical procedures due to other health conditions or those who prefer a less aggressive approach. The procedure offers advantages such as being performed in an outpatient setting and avoiding external incisions.
Compared to traditional open surgeries for BPH, TUNA carries a lower risk of side effects, such as retrograde ejaculation. It provides an alternative for men seeking symptom relief with a shorter recovery time. Discussing options with a healthcare provider is important to determine if TUNA aligns with individual health needs and treatment goals.
