Clinical Features

  • Incidence

    Müllerianosis of the urinary tract is a rare lesion and it occurs in approximately 1% of women with endometriosis; the bladder is the organ most frequently involved (Raspollini and Lopez-Beltran 2019).

  • Age

    Müllerianosis affects mainly reproductive age women.

  • Sex
