Urinary and Genital Disorders (Children)

Swollen Testicles



My son has recently been treated for Kawasaki disease (KD) and he now have swollen testicles. Sometimes it is the left and sometimes it is both. It is not bigger than an egg but it is bigger than it usual size. Can it be an effect of the high dose aspirin or four days worth of IVs or an effect of the KD. His navel area also looks strange. Thanks


The scrotal swelling is often seen in Kawasaki disease and is a result of the vasculitis, not of treatment. Often there is mild associated pain. Treatment generally results in gradually diminished swelling and discomfort. There are many other conditions that can cause testicular swelling; the most serious is testicular torsion, which causes severe pain and swelling. In this condition, a scrotal ultrasound shows reduced flow to the testicle, and nearly always only one side is affected. Treatment is emergency surgical exploration of the scrotum to examine the testicle. In Kawasaki disease, some clinicians exhibit concern regarding the possibility of torsion, but usually the ultrasound shows good flow to the testicles, so no surgery is necessary.
