Abstract

Introduction: Pelvic fractures, although comprising a small proportion of musculoskeletal injuries, are clinically significant due to their proximity to vital anatomic structures. These injuries may carry a mortality rate of up to 20%. The location of the bladder and ureters within the pelvic cavity makes them highly vulnerable to trauma. Urological injuries are reported in approximately 6–15% of pelvic fracture cases. This study aimed to investigate the association between the type of pelvic fracture and the pattern of lower urinary tract symptoms.
Materials & Methods: In this study, medical records of patients diagnosed with pelvic fractures who were admitted to a tertiary referral hospital within 5 years were reviewed. Patients with a history of prior pelvic fractures or urological surgeries were excluded. Data were analyzed using SPSS25 software.
Results & Discussion: A total of 134 patients were included, of whom 86 (64.2%) were male. The mean age was 40.7 ± 21.5 years. The most common fracture type was LC (Lateral Compression) (82.8%), followed by anterior-posterior compression (9.7%) and vertical shear (7.5%). A statistically significant association was found between fracture type and urinary symptoms (P=0.047). Gross hematuria was more frequent in anterior-posterior compression fractures, while microscopic hematuria was more common in vertical shear fractures. Patients with LC fractures were less likely to exhibit urinary symptoms.
Conclusion: The type of pelvic fracture is associated with the presence and nature of lower urinary tract symptoms. Early recognition of this relationship may improve diagnostic accuracy and guide appropriate management in trauma settings.
