[Bilateral tumors of the testis]

Sixteen cases of bilateral tumors of the testicle (1.7% of all patients with tumors of germ origin) were treated at the Clinic of Urology of the Center in 1953-1982. The age of the patients varied 17-54 years (mean age--32.9 years). Cryptorchism was recorded in 2 out of 16 cases. Separate tumor was found to develop in the contralateral testicle in most cases, this factor being of vital importance for the choice of treatment procedure. The results of treatment did not differ from those in cases of unilateral lesions and were chiefly related to stage and microscopic pattern of tumor.
