Question
A 2.5-year-old boy has a scrotal swelling measured at 1 cm by 1.5 cm, as shown by ultrasound. Over the past two months, the swelling has gradually increased to 1 cm by 2.5 cm in size, with no tenderness and no other symptoms present throughout his body.
Answer
Hello, hydroceles are often unilateral swellings, manifesting as an enlarged scrotum that appears like a water sac. The swelling can be as small as an egg, but if left untreated for a long time, it can accumulate a large amount of fluid within the tunica vaginalis, swelling to the size of a fist, causing the penis to retract into the skin. Generally, the scrotum becomes more swollen after daytime activities. If the symptoms are pronounced, surgical treatment is required.
