title: [Simultaneous bilateral Wilms' tumors].
abstract: Wilms' tumors occur in 4-14% bilaterally, partially simultaneously, partially metachronously. Therefore in every case with Wilms' tumor the contralateral kidney has to be examined thoroughly too. 5 children of a series of 52 patients with Wilms' tumor showed simultaneous bilateral occurrence (9,6%). The radiological procedures and their importance in diagnosis of bilateral Wilms' tumor are discussed. The prognosis of simultaneous bilateral Wilms' tumors is much better than that of metachronous ones and almost the same as that of unilateral ones.
