Is it possible to fix a hydrocele without surgery?

No. Sadly not usually. You can drain a hydrocele with a needle in the office but the recurrence rate is very high. In surgery the hydrocele "sac" where the fluid sits is surgically removed so it is very rare for the fluid to return after surgery. Best of luck.

Usually not. Small hydroceles often require no surgery unless they bother the subject. Large hydroceles in very old or infirm subjects can be aspirated coincident with instillation of a sclerosant. By & large adult hydroceles which need to be "fixed" require surgery for correction.
