[Sonography of the scrotal contents].

In 394 patients with various urological symptoms, the content of the scrotum was examined sonographically. 71 testicular lesions were found, 194 extratesticular pathologies were diagnosed. In 69% the enlargement of the testicle was due to a tumor, in 4 patients due to acute orchitis and in 3 patients due to acute torsion. An unilateral smaller sized testicle was found in chronic inflammation [5], cryptorchism [9], hypoplastic testicle [2] and after corticoid medication [1] and radiation therapy [1]. In normal sized testicles 8 tumors, 19 fibromas of the tunica albuginea, 2 scars after trauma and 1 haematoma were found sonographically. In 91% of patients with epididymitis the epididymis was enlarged. The echo structure was altered in 74%, in 13% abscesses were found. Sonography was useful in evaluation of scrotal herniation, especially when combined with hydroceles. Varicoceles were better detected and graduated by sonography than by clinical examination.
