What is a Urinary Fistula?

A urinary fistula is an opening in the urethra that causes urine leakage. When Metoidioplasty is performed with Urethral Lengthening, fistulas most commonly occur at the junction of the native and neourethra (although they can occur anywhere along the neourethra.) A fistula that heals with excessive scarring may eventually lead to stricture formation.

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

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 fistula.

What Causes a Urinary Fistula?

  • Inadequate blood supply to the urethra
  • Too much moisture causing junction of native and neourethra to not heal well
  • Infection
  • Urethral catheters left in too long1

How Is a Urinary Fistula Treated?

While most urethral fistulas can be managed using non-surgical options and/or urinary diversion with a catheter, up to 15% of patients required revision surgery in the study with the longest follow-up duration, to date.2

For fistula repair surgery, Reconstructive Urologist Dr. Dmitriy Nikolavsky uses a fasciocutaneous groin flap or a labial fat pad flap harvested from the neoscrotum.3
