Background: Non-puerperal uterine inversions are rare. The objective of the study was to investigate the frequency, causes, clinical presentations, and management of published case reports of non-puerperal uterine inversion. Material and Methods: We searched MEDLINE, EMBASE, LILACS, the Cochrane Central Register of Controlled Trials, IBECS, BIOSIS, the Web of Science, SCOPUS, Conference Abstracts, and grey literature (Google scholar; the British Library) for papers published from January 1940 through March 2017. Results: We found a total of 170 case reports. The most common cause was leyomioma (57.2%) followed by sarcoma (13.5%). The definitive treatment of most cases was hysterectomy (86.8%). The median hemoglobin levels were seven, showing the severity of the condition by previous vaginal bleeding. All reported cases had a correct management demonstrated by the prognosis until hospital discharge. All patients were discharged, most of them without serious postoperative events. Cancer cases were referred for proper treatment. Only 2 cases of death were reported in 6 weeks and 3 months, respectively, both cases of cancer in advanced stages. Conclusion: Non-puerperal uterine inversion is rare. There have been 170 cases reports in the literature since 1940.
