[Bilateral testicular tumors].

Bilateral testicular tumours account for cca 2-4% of all testicular tumours. In 1975-1989 at the Urological Clinic of the Faculty Hospital with Policlinic in Olomouc a total of 272 patients with testicular tumours were treated, incl. 6 with bilateral tumours which developed successively. The interval between the development of the tumours was on average 5.8 years. All patients survive 1-9 years after the diagnosis of the contralateral tumour.
