Ultrasonic scanning in the evaluation of scrotal swellings.

Typical ultrasonic images of normal testes, hydrocele and cysts of the epididymis, tumors and inflammatory diseases of the testis and epididymis, and injuries of the scrotal organs obtained in the study of 137 patients are presented. The method is simple, harmless and informative. Grey scale scanning was carried out using a water bath, which gives more complete data on the structure of the testis and its epididymis as compared to routine B-mode scanning. Ultrasonography is a reliable aid to the urologist in the diagnosis of scrotal swellings.
