When abdominal fluid flows into the scrotum and gets collected there, the condition is called hydrocele. It does not cause pain but swelling. In babies, hydrocele can disappear on its own. In adults, hydrocele is usually the result of either some inflammation or an injury of the scrotum.
Hydroceles are of two types:- Noncommunicating hydrocele: It is when the sac closes like normal, but the body doesn't absorb the fluid inside it.
- Communicating hydrocele: It is when the sac doesn't seal and has an opening into the abdomen. It causes swelling to the scrotum.
