BackgroundThat the bladder can be compressed by extraperitoneal hematoma induced by obstetrics and gynecologic diseases, is well known. However, there have been no reports on the clinical significance of compressed bladder induced by pelvic fracture (PF). We therefore retrospectively investigated the clinical features of compressed bladder induced by the PF.MethodsFrom January 2018 to December 2021, we performed a retrospective review of the hospital medical charts of all emergency outpatients who were treated by emergency physicians at the department of acute critical care medicine in our hospital, and who were diagnosed with PF based on computed tomography (CT) on arrival. The subjects were divided into two groups: the Deformity group, in which the bladder was compressed by extraperitoneal hematoma, and the Normal group. Variables were compared between the two groups.ResultsDuring the investigation period, 147 patients with PF were enrolled as subjects. There were 44 patients in the Deformity group and 103 in the Normal group. There were no significant differences between the two groups with regard to sex, age, GCS, heart rate or final outcome. However, the average systolic blood pressure in the Deformity group was significantly lower, and the average respiratory rate, injury severity score, rate of unstable circulation, rate of transfusion and duration of hospitalization in the Deformity group were significantly greater in comparison to the Normal group.ConclusionsThe present study showed that bladder deformity induced by PF tended to be a poor physiological sign that was associated with severe anatomical abnormality, unstable circulation requiring transfusion, and long hospitalization. Accordingly, physicians should evaluate shape of bladder when treating PF.Copyright © 2023. Published by Elsevier Inc.
