Clinical Significance of Pyometra

Abstract

Objective: To review the clinical profiles and management outcomes of patients with pyometra.

Study design: A retrospective review of all women admitted with a confirmed diagnosis of pyometra over an 8-year period (January 2003 to December 2010). The medical records, including operation notes, histological and microbiological results, were reviewed.

Results: A total of 57 patients accounting for 76 admissions were identified. The mean patient age was 82.0 ± 11.3 years. The most common presenting symptom was postmenopausal bleeding (59.2%), followed by vaginal discharge (40.8%), fever (6.6%), and abdominal pain (5.3%). Drainage of pyometra was either by uterine Foley catheter insertion (48 patients [84.2%]) or repeated endometrial aspiration (2 patients [3.5%]). Antibiotics were prescribed to 49 patients (86.0%). Diagnostic hysteroscopy with mechanical cervical dilation was performed in 6 patients (10.5%). Gynecological malignancy was identified in only 1 patient, while colorectal cancer was identified in 2 patients. No patient had spontaneous uterine perforation or sepsis. Sixteen patients had recurrent pyometra within a mean follow-up period of 5.1 ± 5.8 months (range, 0.5-23 months).

Conclusion: Pyometra usually presents with postmenopausal bleeding and can be treated with drainage and antibiotics treatment. In contrast to previous reports, our study indicates that spontaneous uterine perforation and gynecological malignancies are not commonly associated with pyometra.
