Combined vesical and abdominal endometriosis following abdominal hysterotomy and tubal ligation

The article reports on the case of a 29 year old patient who developed abdominal endometriosis 4 years after having had hysterotomy and tubal ligation. About a month after the excision of the endometrial tissue she was examined for suprapubic pains, strangury, and frequency of micturition. A nodule was found in the deepest part of the abdominal wall and the patient was treated for 6 months, without success, with medroxyprogesterone acetate. A subsequent laparotomy showed bladder endometriosis, obviously still an endometrial implant at the time of hysterotomy, which was missed at the time of the first excision. Total hysterectomy was carried out and the patient recovered successfully. Bladder endometriosis is the most common site of involvement among urinary tract endometriosis. The peculiarity of the case presented here is in the total absence of hematuria, and in the fact that pains had no relation with the menstrual cycle. Hormonal therapy is often ineffective, and surgery often the only advisable form of treatment.
