What is a Urethral Stricture?

Urethral stricture is a narrowing or closure of the new urethra caused by scar tissue in the urethra. Urethral stricture is a complication that typically develops 6-12 months after Metoidioplasty. Symptoms include a weak urine stream and difficulty urinating.

While there aren't enough studies to offer precise estimates of the risk of stricture some reliable data exists:

How Is a Urethral Stricture Treated?

Successfully treating urethral strictures in Metoidioplasty patients can be challenging for several reasons:1

  • Absence of corpus spongiosum leads to poor coverage of any urethral reconstruction.
  • Absence of foreskin, elastic penile skin, and scrotal skin makes reconstruction with preputial, penile, and scrotal skin grafts or flaps impossible.
  • Wound-healing problems can lead to dense local scar tissue.
Dr. Dmitriy Nikolavsky Reconstructive Urology is a sub-specialty of urology that focuses on restoring normal function in the urinary tract. A reconstructive urologist has the experience and specialized training necessary to treat complications arising from Phalloplasty surgery. Dr. Dmitriy Nikolavsky is Assistant Professor of Urology and Director of Reconstructive Urology at Upstate University Hospital in Syracuse, New York. Dr. Nikolavsky provides urological care for patients experiencing complications following Phalloplasty, such as urethral strictures.

There are a number of different treatment options depending on the size and location of the stricture:2

  • For short strictures near the tip of the penis, a small cut can be made to enlarge the opening of the urethra.
  • For short strictures in the junction of the of the native and neo urethras, excision and closure of the stricture may be possible.
  • For longer strictures in the junction of the of the native and neo urethras, or in cases where the above solution failed, excision and closure of the stricture augmented by buccal (inside of cheek) or bladder mucosa can be done in a single stage.
  • For longer strictures in the shaft of the penis, or in cases where the above solution failed, excision and closure of the stricture augmented by buccal mucosa (inside of cheek)—or less commonly, remnants of vaginal mucosa, or rectal mucosa—can be done in in two stages, separated by 6 months.
  • If difficult cases of persistent strictures, a final option is to relocate the urethra back to the perineum. Standing up to urinate without a device would not be possible.
