Blunt bladder trauma: manifestation of severe injury.

Twenty-nine patients with bladder injuries requiring operative treatment as a result of blunt trauma are presented. Motor vehicle accidents accounted for 86 per cent of the injuries. Hypotension and gross hematuria were the most prevalent clinical features, 68 per cent and 97 per cent, respectively. All patients had multiple associated injuries requiring operative treatment, average 2.9 per patient. Pelvic fractures occurred in 93 per cent and intra-abdominal injuries in 48 per cent of patients. The majority of ruptures (72%) were intraperitoneal. Mortality, related to associated injuries, was high (34%), attesting to the magnitude of injury sustained by the victim.
