Transurethral needle ablation of the prostate

Transurethral needle ablation of the prostate (TUNA) is a medical procedure used to treat benign prostatic hyperplasia (BPH), a condition characterized by the enlargement of the prostate gland. This procedure is minimally invasive and is performed using a cystoscope, a thin tube with a light and camera at the end.

Procedure

The TUNA procedure involves the insertion of a cystoscope into the urethra through the penis. Once the cystoscope reaches the prostate, two needles are extended into the prostate tissue. These needles emit radio waves that generate heat, causing the excess prostate tissue to be destroyed. The procedure typically takes less than an hour and is performed under local anesthesia.

Benefits and Risks

The benefits of TUNA include a lower risk of complications compared to more invasive procedures, shorter recovery time, and the ability to perform the procedure on an outpatient basis. However, potential risks include urinary tract infection, blood in the urine, and difficulty urinating.

Post-Procedure Care

After the procedure, patients may need to use a catheter for a few days until they can urinate on their own. Regular follow-up appointments are necessary to monitor the patient's progress and to check for any complications.
