[Modern aspects of diagnosis and therapy of Wilm's tumor].

Real-time sonography of 12 cases with Wilms' tumour confirmed by the pathohistological finding was presented according to the ultrasonographic picture and the possibilities of radiotherapeutic treatment in dependence of the degree of disease. Uniform, irregularly reflective appearance of the tumourous tissue was observed in 58.3% of the patients, while the areas of necrosis and/or hemorrhage and cystic degeneration in the tumour accounted for 41.7%. Clear determination between the tumour and the normal parenchyma of the kidney was confirmed in 66.6% of the cases, while visualization of the normal tissue of the kidney was not possible in 25% of the patients. The treatment of patients with Wilms' tumour was narrowly coordinated by the program consisting of the surgical extirpation of the tumour, postoperative irradiation of the tumorous area at degrees II, III, IV and V and intensive adjuvant chemiotherapy.
