Paediatric Genital Abnormalities
Hydrocoeles are cystic fluid collections that are either still communicating with the abdominal cavity or sealed off. They can be firm or soft and may surround the testis or be encysted in the cord.
They usually resolve by the age of 2 years and could be surgically corrected after that time if they are very large or appear to be causing discomfort. They are normally painless. Communicating hydrocoeles can vary in their size particularly with straining or crying.
Transillumination is the most useful clinical sign to show they are fluid filled and excludes a hernia.
