In the case of scrotal disorders, tests such as scrotal ultrasound, physical examination or scrotaloscopy are needed to further define the specific condition. If the scrotum is simply swollen, ultrasound can be performed, through ultrasound examination can understand the cause of scrotal swelling, such as the presence of scrotal wall edema, the presence of intra-scrotal sheath effusion. If it is a localized scrotal skin lesion, such as the presence of localized skin ulceration or localized scabies nodules and so on, it is necessary to observe the size of the specific lesion, the scope of its surface exudate, but also have access to the local secretions to do the relevant laboratory tests, such as bacterial smears, bacterial culture test. For hard-to-diagnose scrotal lesions, further scrotaloscopy can be performed, which is a surgical procedure that involves making a small incision in the scrotum. A special scope is then used to enter the scrotum to directly visualize the scrotal lesion and obtain a biopsy, and treatments such as syringomyelia aspiration or localized sclerotherapy can also be performed under scrotaloscopy.
