Park, Tong Choon

Abstract

Clinical observations were made on l23 patients with pelvic fractures and 78 patients with 1ower urinary tract injury in the Kyungpook National University Hospital during the period of 6 years from Jan., 1968 to Dec., 1973. The results were as follows: 1) The most common cause of pelvic fractures was traffic accident (78.9%), and the age group ranging from 20 to 39 years of age was 50.4% of patients with pelvic fracture. 2) Of l39 pelvic fractures in 123 patients, unilateral pubic rami fractures were most common (31.7%), and followed by bilateral pubic rami fractures (25.9%), Malgaigne fractures (22.3%). acetabular fractures (8.6%), and separation of the symphysis pubis (5.8%) in order of frequency. 3) 38 cases (30.9%) of the pelvic fractures were associated with lower urinary tract injuries. From the view of fracture pattern, 47.2% of bilateral pubic rami fractures, 38. 7% of Malgaigne fractures, 25.0% of separation of the symphysis pubis and 13.6% of unilateral pubic rami fractures were associated with lowed urinary tact injuries. 4) The most common cause of lower urinary tact injuries associated with pelvic fracture was traffic accident (81.6%), and that of those not _associated with pelvic fracture was fall-down including the straddle injury (62.5%). 5) The other associated injuries were more common in cases with pelvic fracture (39.5%) than in those without pelvic fracture (22.5%). 6) Complications of urethroplasty were also more frequently observed in urethral ruptures with pelvic fracture (42.3%) than in those without pelvic fracture (23.5%). 7) Mortality rate of the lower urinary tract injuries was 3.8%, and all the deads were observed in cases associated with pelvic fracture.
