Urethral diverticulum (UD) is a pocket or pouch that forms along the urethra. Because of its location, it can be filled with urine and lead to infections. It is can cause:

  • A painful vaginal mass
  • Ongoing pelvic pain
  • Many urinary tract infections (UTI)

It is rare, but more common in women between age 40 and 70. Children are not usually affected, unless they've had urethral surgery.

With better imaging, more UDs have been found and treated. Still, many cases are missed or misdiagnosed simply because no one considered it.
