Endometriosis of the bladder as a cause of obstructive uropathy

A 47-year-old woman (gravida 1, para 1) with menorrhagia and pelvic pain was found to have an enlarged fibroid uterus and bladder mass on ultrasonographic imaging. The patient underwent an abdominal supracervical hysterectomy and transurethral bladder mass resection. Histopathologic findings revealed leiomyoma uteri, intramural adenomyosis, and bladder endometriosis. Most case series of bladder endometriosis include women that present with urinary symptoms. This is a rare case of obstructive uropathy secondary to bladder endometriosis in a patient without any urinary signs or symptoms.
