[Current diagnosis of pediatric kidney trauma: consequences for therapy planning].

For the therapy of pediatric renal trauma there is always the question of the appropriate diagnostic measures. The various procedures such as ultrasound, urography, scintigraphy, computed tomography, conventional angiography, arterial and venous digitalized subtraction angiography are discussed. By these new methods it is possible to judge the severity of renal trauma more accurately and to limit the indications for an operation. With stable circulation an operation should only be performed in the presence of a large, expanding retroperitoneal hematoma, extensive extravasation (urinoma), persistent massive hematuria or if large areas of devitalized renal tissue are found.
