[Bilateral renal tumors]

At the Urological Clinic in Hradec Králové in 1990-1994 320 patients with renal tumours were admitted and treated. In 12 the tumour was bilateral (3.7%), incl. 8 patients where it was synchronous and four where it was asynchronous. Only in one female patient bilateral nephrectomy was performed, in 8 patients unilateral nephrectomy and on the other side enucleation of the tumour, in two patients bilateral enucleation of the tumour and in one patient with a malignant lymphoblastic lymphoma only unilateral enucleation of the tumour and epinephrectomy. In 10 patients histological examination confirmed a renal carcinoma, in one patient a malignant lymphoblastic lymphoma, in one female patient a bilateral multifocal oncocytoma. The patients survival was not evaluated in the report.
