[Blunt kidney injury--the use of AAST score (American Association for the Surgery of Trauma)--own observations].

Thirty six patients with blunt kidney injury were qualified for the treatment based on the results of present diagnostic methods and AAST (American Association for the Surgery of Trauma) scale. In all of them ultrasonographic exam was performed. It was abnormal in 38.9% of patients. This abnormality was confirmed in intravenous urography in 36.1% patients; 86.1% of them were treated conservatively, while the rest (13.9%) was operated on. For the correct diagnosis and qualification for the treatment, contemporary standards containing a general condition and radiographic examination results were applied.
