Abstract

Title of paper: New Onset Urological Complication In Pelvic Fractures: Predictors Of bladder Injury, Urethral Injury, Urinary Retention And Urinary Incontinence Following Pelvic Fractures

Objectives: This study aims to identify the incidence of urological complications named bladder injury, urethral injury, urinary retention and urinary incontinence following pelvic fractures and examine the patient’s age, sex, fracture type and mechanism of injury as possible predictors.

Methods: A retrospective cohort study that was conducted in two general hospitals and included patients who had pelvic ring fractures between January 2021 and March 2024. Data were gathered using the patients’ files and database.

Results: 45 patients were included. With regards to complications, 2(4.4%) of the patients experienced urethral injury, 4(8.9%) had bladder injury, 6(13.3%) suffered from urinary incontinence, and 2(4.4%) experienced urinary retention. Regarding the examined predictors, both age and sex did not show a statistically significant value. Regarding the young-burgess classification, APC III injuries were particularly associated with 1 urethral injury, 3 bladder injuries, and 2 urinary retention cases. Patients with APC III injuries had increased probability to sustain bladder injuries (OR- 14.649, p = 0.057). In terms of the mechanism of injury named road traffic accident, fall from height, injury with heavy object and fall from stairs, road traffic accidents were the most common accounting for 51.1% of the cases. However, fall from stairs was identified as the only MOI that showed a statistically significant value in relation to urethral injuries.

Conclusion: This study shows a significant association between APC III pelvic fractures and bladder injuries and urinary retention. The results show that the type of fracture and its mechanism of injury play more significant roles in predicting urogenital complications, compared to factors like age and gender. Early diagnostic interventions and management strategies based on these factors are essential in improving patient outcomes. Although the study provides valuable insights, further research with larger sample size is needed to develop predictive models for more effective management.
