title: [Ultrasonic examinations of Wilms' tumors stage II-V during preoperative therapy (author's transl)].
abstract: Ultrasonic examinations were performed at weekly intervals in 8 patients with Wilms tumors Stage II-V during the period of preoperative therapy. Measurements of the maximum expansion of the tumors were made and expressed in an ellipsoid formula. The tumor volume was thus calculated. A description of the compactness of the tumor as well as the bordering of the tumor were done. This was followed by a photographic documentation. The mean value of the initial tumor volume in the 8 patients was 551 ml. At the end of the preoperative therapy, an average volume of 305,1 ml was recorded. One week after beginning the therapy, 25-40% diminution of the initial tumor volume was noted in 5 patients. The diminution in volume till tumor extirpation was in all 49%. In 3 patients, the reduction of tumor mass through therapy was only 27,8%. The histological examinations revealed a fetal rhabdomyomatic nephroblastoma in one case. The second case was massive tumor haemorrhage and in the third case a considerable formation of cysts.
