Incidence of genitourinary injuries in pelvic fractures: A 12-year single-center retrospective study

Objective This study aimed to determine the epidemiology of genitourinary injuries in pelvic fractures and elucidate the clinical outcomes of patients with pelvic fractures with and without genitourinary injuries at a tertiary trauma center in Japan. Methods Patients with pelvic fractures in our tertiary trauma center between May 2009 and April 2021 were retrospectively assessed. The patients' demographics, mechanism of injury, and hospital course details were collected. The outcomes of patients with pelvic fractures with and without genitourinary injuries were compared. Results Of 402 patients with pelvic fractures, 18 (4.5%) had genitourinary injuries. Falls were the most common mechanisms of injury for all pelvic fractures The incidence of bladder, kidney, urethral, and testis injuries were 2.0%, 1.2%, 1.2%, and 0.5%, respectively. Patients with genitourinary injuries were significantly younger (median age, 26 vs. 51 years; p < 0.001), had a higher rate of intensive care unit admission (94% vs. 58%; p = 0.002), remained hospitalized longer (median duration, 82 vs. 45 days; p < 0.001), and had a longer intensive care unit stay (median duration, 6 vs. 2 days; p < 0.001) when compared to patients without genitourinary injuries. Genitourinary injuries were not associated with in-hospital mortality. Conclusions The incidence of genitourinary injuries with pelvic fractures was 4.5%. The presence of genitourinary injuries was associated with a higher rate of intensive care unit admission, longer hospital stay, and longer intensive care unit stay, but it was not associated with in-hospital mortality.
