[Value of nuclear medicine and ultrasonography in the management of renal trauma (author's transl)].

Intravenous urography remains the most decisive investigative method in the management of blunt renal trauma. Even minor urographical changes would merit scintiscan and ultrasound examination in order to visualize or rule out parenchymal lesions, intra- or extrarenal hematomas and urine extravasation as well as assess respirational excursions of the kidney. Follow-up studies may be performed without hesitation. Major lesions (primarily a urinoma) and alarming clinical findings necessitate further diagnostic procedures (angiography, possibly after computer tomography). In case of a surgical intervention, angiography cannot be replaced by any other diagnostic method to date. There are no comparative studies of patients with similar injuries managed alternatively with immediate operation or a conservative approach. However, based on our diagnostic possibilities and therapeutical results, we are in favor of a more expectant management of major renal trauma.
