Aspiration: very rarely, if ever. However aspiration may be an option if the diagnosis is in doubt. I may consider aspiration if the patient has a very large hydrocele and absolutely refuses surgery. Aspiration is not favoured because the hydrocele will refill, and can develop infection. In the past aspiration, with injection of a chemical, was popular. This treatment has poor results and has now been abandoned. Hydrocelectomy is a must if large, and troublesome. If the hydrocele is small, and does not interfere with routine activity or walking, if it is painless, it can be left alone. Chennai: I do not know. Cost: In Delhi, in a private hospital, varies according to hospital, but averages Rs. 5000/- inclusive of medicines.
