Predictive Factors of Lower Urinary Tract Injuries and Spontaneous Voiding Failure After Pelvic Fractures.
In vivo (Athens, Greece)(2023)
Abstract
BACKGROUND/AIM:This study aimed to describe the voiding patterns of patients after surgical treatment of pelvic fractures and determine the predictive factors of lower urinary tract injuries (LUTIs) and spontaneous voiding failure among patients with surgically treated pelvic fractures at a tertiary trauma center in Japan.
PATIENTS AND METHODS:We retrospectively assessed patients with surgically treated pelvic fractures in our tertiary trauma center during May 2009-April 2021. We excluded patients who died during hospitalization and who had indwelling catheter prior to the injury. Patients' LUTIs and spontaneous voiding failure at discharge were recorded. Multivariate analysis was performed to assess the predictive factors of LUTIs and spontaneous voiding failure at discharge.
RESULTS:In total, 334 eligible patients were identified. Among them, 301 patients (90%) voided spontaneously with or without diapers at discharge. Thirty-three patients required some form of catheterization for bladder drainage. LUTIs were found to be associated with chronological age [odds ratio (OR)=0.96; 95% confidence interval (CI)=0.92-0.99; p=0.024] and pelvic ring fracture (OR=12.0; 95%CI=1.39-255.2; p=0.024). Spontaneous voiding failure was associated with intensive care unit admission (OR=7.17; 95%CI=1.49-34.4; p=0.004).
CONCLUSION:Overall, 10% of patients with surgically treated pelvic fractures were not able to void spontaneously at discharge. Spontaneous voiding failure after pelvic fractures was related to injury severity.
