Analysis of Lower Urinary Tract Injury Associated with Pelvic Fracture / 대한비뇨기과학회지

ABSTRACT

PURPOSE: The purpose of this study was to determinate a relationship of pelvic fracture, lower urinary tract injury and injury severity scale (ISS) in multiple organ injury patients. MATERIALS AND METHODS: We retrospectively reviewed the results collected from 54 cases with pelvic fracture associated with lower urinary tract injury during the period of 6 years. Emphasis was placed on the relationship of location of pelvic bone fracture, number of fractured rami, lower urinary tract injury and ISS. RESULTS: The most common cause of pelvic fracture was traffic accident giving the rate of 65.5% (38 cases). The highest score of ISS was 39.3 in pedestrian injury. Fracture of unilateral multiple rami was most common (29.3%). Among lower urinary tract injuries, urethral injury was most common giving the rate of 44.8% (26 cases). Among single urethral injuries, the type I injury was most common (50%). Suprapubic cystostomy was most common method (44.8%) in initial management. Complications of lower urinary tract injury were predominant in urethral injury and most common complication was urethral stricture (44.8%). Mortality rate was 5.2%. CONCLUSIONS: The risk of urethral injury is influenced by the number of broken pubic rami, but bladder injury by fractured bone site. ISS score was correlated with mortality rate.
