RisksBy Mayo Clinic staff
Risks of TUMT include:
- Urinary retention. You may 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. 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.
- Need for retreatment. Most men who have TUMT will 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
- Urethral stricture — narrowing of urethra
- Radiation treatments in the pelvic area
