What is Transurethral Needle Ablation (TUNA)?
Transurethral Needle Ablation (TUNA) is a minimally invasive procedure used to treat urinary symptoms caused by benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland. During TUNA, low-level radiofrequency energy is delivered through small needles inserted into the prostate via the urethra. This energy heats and destroys excess prostate tissue, helping to relieve urinary obstruction and improve urine flow.
What are the Benefits of Transurethral Needle Ablation (TUNA)?
Transurethral Needle Ablation (TUNA) offers several advantages for men seeking relief from BPH symptoms. It is less invasive than traditional surgery and is often performed on an outpatient basis.
- Minimally invasive with no external incisions
- Reduced risk of bleeding compared to open surgery
- Can often be performed under local anesthesia
- Shorter recovery time
- Improvement in urinary flow and symptom relief
- Lower risk of sexual side effects compared to some surgical options
When is Transurethral Needle Ablation (TUNA) Recommended?
Transurethral Needle Ablation (TUNA) is typically recommended for men with moderate lower urinary tract symptoms due to BPH who have not responded well to medications. It may also be considered for patients who are not ideal candidates for more invasive surgery.
- Frequent or urgent urination
- Weak urine stream or difficulty starting urination
- Incomplete bladder emptying
- Symptoms not controlled with medication
- Patients seeking minimally invasive treatment options
What does preparation for Transurethral Needle Ablation (TUNA) involve?
Preparation for Transurethral Needle Ablation (TUNA) includes a detailed evaluation of urinary symptoms, prostate size assessment, and review of medical history. Patients may undergo urine tests, blood work, or imaging studies. Doctors may advise stopping certain medications, especially blood thinners, before the procedure. Fasting instructions may also be given if sedation is planned.
How is Transurethral Needle Ablation (TUNA) performed?
Transurethral Needle Ablation (TUNA) is performed using a specialized cystoscopic device inserted through the urethra. Once positioned in the prostate, fine needles are deployed to deliver controlled radiofrequency energy. This heat destroys targeted prostate tissue while protecting surrounding structures. The procedure typically takes less than an hour and is often done on an outpatient basis.
What to Expect during Recovery after Transurethral Needle Ablation (TUNA)?
After Transurethral Needle Ablation (TUNA), patients may experience mild burning during urination, increased frequency, or slight discomfort for a few days. Most individuals can return to normal activities within a few days, though full symptom improvement may take several weeks as the body clears treated tissue.
What are the Risks and Complications of Transurethral Needle Ablation (TUNA)?
Although Transurethral Needle Ablation (TUNA) is generally safe, some risks and complications may occur.
- Temporary urinary retention
- Urinary tract infection
- Blood in urine or semen
- Mild pelvic discomfort
- Rare need for repeat treatment due to symptom recurrence
