A 57-year-old man had had scrotal swelling for a couple of years. The swelling had now increased. Clinical examination suggested bilateral hydrocoele, but ultrasongraphy revealed fluid only on the left side where the testicle is visible behind the fluid. There is no fluid surroinding the right testicle. The fluid was removed via an infusion cannula after local anaesthesia. After most of the fluid had been removed, a solution containing 2 ml of 3% polidocanol diluted with 5ml of 1% or 2.5% lidocaine was injected into the hydrocoele . See also video .
