The intrauterine device and tubo-ovarian abscess.

During the past 4 years, 16 patients have been seen who developed a unilateral tubo-ovarian abscess while wearing, or soon after removal of, an IUD. None of the patients had gonorrhea. There appears to be a prodromal syndrome before abscess formation of 2 to 5 weeks during which the patient complains of vague lower abdominal pain, pelvic tenderness, and dyspareunia. A few patients had a rapid onset of symptoms. The device should be removed when prodromal symptoms arise and the patient should be treated with antibiotics. Should a tubo-ovarian abscess develop, surgical intervention is necessary.
