This complaint forms a pear-shaped swelling, smooth on its outer surface, fluctuating if pressed, free from pain and tenderness, and causing merely a little uneasiness by its weight. On placing a lighted candle on one side of the scrotum the light can be seen through it.

Hydrocele may be a consequence of inflammation of the testicle, but it more frequently arises without any local cause. It is often supposed to follow strains of the loins or belly.

Solid enlargements of the testicle may be distinguished from Hydrocele by their weight, solidity and greater painfulness, and by the absence of fluctuation and transparency.

Treatment

The remedies for Hydrocele are of three kinds. First, the application of cooling lotions, (.Nos. 42 or 44 may be used,) which sometimes assist the cure in children, but cannot be depended on for adults. Secondly, evacuation of the liquid, which is usually done with a large needle. This treatment is always sufiicient for children, and sometimes for adults. The third method, which is called the radical cure, is accomplished by first drawing off the liquid and then injecting a mixture of equal parts of port wine and water, or Sulphate of Zinc Lotion, into the empty sac. This is allowed to remain from three to five minutes, when it is withdrawn. It usually causes a little inflammation, but cures the complaint.
