Comparison of results of treatment of hydrocele and epididymal cysts by surgery and injection.

A comparison has been made between a series of hydroceles and cysts of epididymis treated by surgery with a complication rate of at least 17% haematoma and 10% sepsis, an average hospital stay of five days, and a much longer time off work, and a series treated by tapping and injection (described in detail) requiring one to three visits to outpatients, an almost negligible complication rate, and no failures in those completing treatment.
