An analysis of urinary tract trauma in Scotland: Impact on management and resource needs

Objective: We report the incidence, distribution, aetiology and outcome of urological trauma in a unique national database to provide an insight into its contemporary management. Patients and Methods: The Scottish Trauma Audit Group prospectively collected data from severe trauma presenting to all major Scottish hospitals. We examined data from 24,666 trauma admissions from 1999 to 2002. Patients who sustained urological injuries were identified and studied in detail. Results: 362 patients had urological injuries, comprising 1.5% of the trauma population, and an incidence of 1 per 45,000 head of adult population per year. Blunt injury (n =285, 79%) was the main cause of urological trauma. Road traffic accidents were most frequent (197 patients, 54%), followed by assaults (76, 21%) and high falls (45, 12%). Renal injuries were the most common (n=241, 67%), followed by injuries to the external genitalia (71, 20%), bladder (65, 18%), urethra (16, 4%) and ureter (3, 1%). Only 52 patients (14%) had isolated urological trauma. One hundred and fifty nine out of 310 (51%) urological patients with associated injuries were physiologically compromised on arrival in A&E, compared with only 4/52 (8%) patients with isolated urological trauma. All patients with isolated urological trauma survived, whereas 110/310 (35%) of those with associated injuries died. Conclusion: Urological injuries in Scotland mostly result from blunt trauma due to high-energy impacts. Isolated urological injuries are uncommon and all such patients survived. The majority of patients with urological trauma have multiple injuries and require a multi-disciplinary approach. Current urological services appear adequately distributed to cope with contemporary demands of urological trauma
