[Ultrasonography in the diagnosis of testicular tumors].

Ultrasonographic examination of scrotum has become a stable part of urological practice. A palpation finding of scrotum or a condition when it cannot be examined by palpation represent the most frequent indications, followed by search for primary tumour, etc. The technique of water sac is useful and rapid. The examination may differentiate intratesticular processes, mostly of tumorous origin, e.g. seminoma, embryonal carcinoma and teratocarcinoma from extratesticular processes, e.g. a large hydrocoele, hematocoele, spermatocoele, epididymal cyst, orchitis, etc. Even though the ultrasonographic picture of the testis tumours are not specific, there is a possibility to hypothesize their histological structure in some cases. Ultrasonographic examination represents an unquestionable diagnostic progress.
