Question

_________ is a diagnostic test to confirm the presence of a hydrocele by shining a bright light on the scrotal swelling to see the shape of the testis through the surrounding translucent excess fluid.

Answer 1

The answer is Transillumination

When the testicles descend into the scrotum in infants, the fluid in the scrotum is usually reabsorbed into the body within a year, and the channel for this fluid closes. However, when this reabsorption and closure of the opening fails, a hydrocele forms.
To diagnose a hydrocele, a physical examination by a physician is done by shining light through the scrotum to check for the presence of fluid.
