Transurethral Needle Ablation - TUNA (Prostiva) |
The TUNA (Medtronic) System is a minimally invasive technique, similar in setup to an office cystoscopy whereby a low-level radiofrequency (RF) energy is delivered directly through the cartridge into the prostate. Twin needles deliver the RF energy into the prostate to destroy areas of the prostate through coagulative necrosis.
Prior to the procedure the patient takes an antibiotic,anti inflammatory,alpha blocker,sedative and an antispasmodic.
Immediately before the procedure he undergoes a transrectal periprostatic nerve block and then intravesicle installation of local anesthetic for regional anesthesia. The small catheter is removed and the cystoscope introduced to commence the procedure.
This office procedure takes about an hour and is designed to improve a man's voiding function to the point where we may stop his prostate medications and/or avoid the possibility of inpatient prostate surgery.
Catheterization may be needed for a few days. The TUNA therapy has few side effects and is covered by Medicare.
