Transurethral needle ablation can be used to treat benign prostatic hyperplasia (BPH). [4] 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.
Transurethral needle ablation (TUNA) operates with a different type of energy, radio frequency (RF) energy, but is designed along the same premise as TUMT devices, that the heat the device generates will cause necrosis of the prostatic tissue and shrink the prostate. The TUNA device is inserted into the urethra using a rigid scope much like a ...
It is an alternative treatment to pharmacotherapy such as alpha blockers, transurethral resection of the prostate (TURP), transurethral needle ablation of the prostate, photoselective vaporization of the prostate and prostatic removal or prostatectomy. [2]
The equipment consists of a vapor generator and a transurethral delivery device. The latter is similar to a cystoscope with an optical system with a 90° extending retractable 10.25 mm long injection needle (diameter 1.3 mm). From this needle water vapor is circumferentially delivered via 12 holes at the needle’s tip.
Transurethral needle ablation of the prostate has been shown to be ineffective in trials. [ 60 ] Neuromodulation has been explored as a potential treatment option for some time.
Benign prostatic hyperplasia (BPH) is the most common cause, [2] but obstruction may also occur acutely after treatment for BPH such as transurethral needle ablation of the prostate (TUNA), transurethral resection of the prostate (TURP), transurethral microwave thermotherapy (TUMT), prostate cancer or after radiation therapy.
Minimally invasive procedures include transurethral needle ablation of the prostate and transurethral microwave thermotherapy. [31] These outpatient procedures may be followed by the insertion of a temporary stent, to allow normal voluntary urination, without exacerbating irritative symptoms. [32]
If medical treatment does not reduce a patient's urinary symptoms, a TURP may be considered following a careful examination of the prostate or bladder through a cystoscope. If TURP is contraindicated, a urologist may consider a simple prostatectomy , in and out catheters, or a supra-pubic catheter to help a patient void urine effectively. [ 3 ]
