RESUMO
OBJECTIVE: Vaginal hysterectomy with uterosacral ligament suspension (VUSLS) is a common procedure for apical prolapse repair. Data regarding pelvic hematoma following this procedure is scarce. The aim of this study was to describe the occurrence of infected and non-infected pelvic hematoma in women following VUSLS and to assess for specific risk factors for infection. METHODS: We performed a retrospective cohort study, including all women who underwent VUSLS for treatment of apical prolapse between 2010 and 2020. Patients with and without pelvic hematoma by ultrasound were compared. A subgroup analysis compared patients with infected vs non infected hematomas. RESULTS: During the study period, 316 women underwent VUSLS for treatment of apical prolapse. Sixty-six (20.9%) were diagnosed with a pelvic hematoma, and in seventeen (5.4%) women the hematoma became infected. The majority (76%) of pelvic hematomas were located above the vaginal cuff. Women in the hematoma group had increased rates of hypothyroidism and concomitant anterior colporrhaphy. However, following multivariate analysis, these differences were no longer significant. Subgroup analysis comparing women with infected versus non-infected pelvic hematoma was performed. No differences were noted with respect to surgical outcomes (clinical, anatomical, or composite). Women with infected hematoma had higher rates of posterior colporrhaphy during surgery (33.3% vs 9.5%, p = 0.039). This difference remained significant following multivariate analysis (aOR = 8.87, CI 1.1-73.0). CONCLUSION: Pelvic hematoma following VUSLS is common as opposed to infected pelvic hematoma which seldom occurs. Concomitant posterior colporrhaphy was associated with infection.
