Can a hernia belt be used for hydrocele? Basically, a hernia belt is of no use for hydrocele. First, you need to understand the difference between hydrocele and hernia. What is a hernia? A hernia occurs when there's a hole in the groin area through which abdominal organs such as the omentum, intestines, and abdominal fluids can leak into the scrotum. By simply covering this hole, the descent of these abdominal contents can be prevented, which is the function of a hernia belt. What about hydrocele? It occurs when the processus vaginalis does not close properly or at all. Usually, it's still small enough that only abdominal fluids can leak into the scrotum, but larger organs like the intestines cannot descend. Therefore, using a hernia belt is ineffective for a hydrocele because there's no hole in the groin area that needs covering or blocking. Hence, a hernia belt is useless for hydrocele.
