Scrotal ultrasound: It is mainly used to observe the testicles, cryptorchid testis, epididymis testis and spermatic vein, to rule out whether there is any enlargement and inflammatory changes in the testicles, as well as whether there is cryptorchid testis, epididymis testis, varicose veins of spermatic vein and other diseases; 2. Prostate ultrasound: it can be used to measure the size of the prostate gland and check whether there are hyperplasia, cysts, stones and other lesions in the prostate gland. 3.

It should be noted that, if you need to carry out men’s genital ultrasound, it is recommended to drink more water to hold urine, so that the bladder is full, so as to facilitate the examination, but the specific operation should be communicated with the doctor.
