尿路外傷と交通事故

Abstract

1 Medical follow-up studies on urinary tract injuries due to traffic accidents in Japan were attempted. The traffic police statistics were of little help for this purpose. 2 Recently, traffic accident has been increasing its significance as a cause of urinary tract injuries in Japan. At the present time, about fifty per cent of the injuries are estimated due to traffic accident. 3 In Japan, the pedestrians are the first victims followed by the motorcycle riders. 4 In Japan, injury of the urethra associated with pelvic fracture comes to the first place. 5 Complicated urinary tract injury due to traffic accident often results in the intractable urinary fistula formation. Tissue viability test with alphazurine 2-G (Patent Blue) was helpful in one case to remove the devitalized scar tissue caused by urinary extravasation, thus promoting spontaneous closure of the fistula. 6 An experiment on rupture of the kidney, bladder, testis, liver and spleen was carried out to test their vulnerability. The first three organs were more resistant than the liver and spleen.
