TUNA is generally safe with few if any major complications. Possible risks of TUNA include:

  • New onset or worsening urinary symptoms. Sometimes TUNA can result in a chronic inflammation within the prostate. The inflammation can cause symptoms including a frequent or urgent need to urinate, and painful urination.
  • Temporary difficulty urinating. You might have trouble urinating for a few days after the procedure. Until you can urinate on your own, you will need to have a tube (catheter) inserted into your penis to carry urine out of your bladder.
  • Urinary tract infection. This type of infection is a possible complication after any prostate procedure. An infection is increasingly likely to occur the longer you have a catheter in place. You will likely need antibiotics to treat the infection.
  • Erectile dysfunction. The risk of erectile dysfunction after prostate treatments is small and generally lower with TUNA than with traditional surgery.
  • Need for retreatment. TUNA might be less effective in treating urinary symptoms than other minimally invasive treatments, or surgery. You might need to be treated again with TUNA or another BPH therapy.
