Selective diagnostic uroradiography for trauma.

Fifteen years of personal experience have yielded 157 penetrating and 225 blunt urological injuries, including only 2 instances of simultaneous upper and lower tract involvement (0.5 per cent). A similar review of 2,750 cases from the urological literature has yielded only 17 patients with simultaneous upper and lower tract injuries (0.6 per cent). Blunt trauma was responsible in all but 1 of these 17 patients (95 per cent). Based upon these observations, it is suggested that comprehensive radiographic evaluation of traumatic hematuria or suspected occult urological trauma unnecessarily may be expensive and dilatory, and that evaluation may be limited routinely to the area of maximum injury.
