RisksBy Mayo Clinic staff
Risks of TUMT include:
- Urinary tract infection. Urinary tract infections are a possible complication after any enlarged prostate procedure. An infection is increasingly likely to occur the longer you have a tube to drain urine (urinary catheter) in place after the procedure. It may require antibiotics or other treatment.
- Narrowing (stricture) of the urethra or bladder neck. Sometimes TUMT narrows the tube that carries urine from the bladder (urethra), or the area where the urethra attaches to the bladder (bladder neck). This can make urination difficult and may require additional treatment to correct.
- Dry orgasm. TUMT can cause retrograde ejaculation, which means semen released during sexual climax (ejaculation) enters your bladder rather than exiting the penis. Retrograde ejaculation isn't harmful and generally doesn't affect sexual pleasure. But it can interfere with your ability to father a child.
- Damage to the genitals. Unintentional overexposure to microwave radiation can cause serious damage to the penis, urethra or other parts of the genital area. This is rare.
- Need for retreatment. Some men who have TUMT later require follow-up treatment with TURP or another prostate procedure. Treatment is needed either because symptoms return or because they never adequately improve.
Because of potential complications, TUMT may not be a treatment option if you have or have had:
- A penile implant
- Certain types of surgery in the pelvic area
- Urethral stricture — narrowing of urethra
- Radiation treatments in the pelvic area
- A pacemaker or an implanted defibrillator — talk with your doctor to find out whether the device can be deactivated for the procedure
