What is a transurethral needle ablation (TUNA)?

Transurethral needle ablation, also known as TUNA or radiofrequency ablation, is a minimally invasive treatment option used to treat benign prostatic hyperplasia. During the procedure, radiofrequency needles are placed through the urethra into the area of the prostate that is pressing on the urethra.

What is transurethral needle ablation?

Introduction to the TUNA Procedure Transurethral needle ablation (TUNA) of the prostate is a procedure used to treat benign prostatic hyperplasia (BPH). It is performed by placing interstitial radiofrequency (RF) needles through the urethra and into the lateral lobes of the prostate, causing heat-induced coagulation necrosis.

How does a tuna system produce thermal tissue ablation?

[ 2] The TUNA system produces thermal tissue ablation by applying low-level RF energy to prostate tissue. The generated RF is in the form of electrical energy and is delivered by the 2 electrodes, which are in contact with the patient.

Can Transurethral needle ablation treat benign prostatic hyperplasia (BPH)?

Transurethral needle ablation can be used to treat benign prostatic hyperplasia (BPH). Some clinical studies have reported that TUNA is safe and effective, improving the urine flow with minimal side effects when compared with other procedures, such as transurethral resection of the prostate (TURP) and open prostatectomy.

How does a transurethral needle ablation work?

Radio waves are sent through the needles, into the prostate tissue to destroy prostate tissue. As a result, the prostate shrinks, which allows urine to flow out the urethra. Who is a candidate for a transurethral needle ablation (TUNA)? TUNA is an option for patients who are suffering from symptoms of benign prostatic hyperplasia.

Can Transurethral needle ablation treat benign prostatic hyperplasia?

Transurethral needle ablation for the treatment of symptomatic benign prostatic hyperplasia [abstract]. Trans-urethral needle ablation (T.U.N.A.) in benign prostatic hypertrophy [abstract]. Transurethral needle ablation (TUNA) of the prostate-one year followup [abstract].
