RESUMEN
A total of 154 children with renal injury have been treated in 1994-2004. In addition to standard examination all the children have undergone ultrasound examination with doppler investigation of renal flow. By severity of renal damage, the patients were divided into three groups. Group 1 consisted of 117 (75.9%) children with lesions of degree I and 11; group 2 (n = 31, 20.1%) - of degree III and IV; group 3 (n = 5, 3.2%) - of degree V. Group 1 children had contusion of the kidney and local subcapsular ruptures of the kidney. They were treated conservatively. Conservative-expectant policy was employed for patients of group 2 who had deep ruptures of the kidney without urinous infiltration or trauma with minimal accumulation of urine. Thirty children were operated. Urgent surgery was indicated in signs of active hemorrhage, hemorrhagic shock.
