The pathophysiology of hydroceles requires an imbalance of scrotal fluid production and absorption. This imbalance can be divided further into exogenous fluid sources or intrinsic fluid production.

Alternatively, hydroceles can be divided into those that represent a persistent communication with the abdominal cavity and those that do not. Fluid excesses are from exogenous sources (the abdomen) in communicating hydroceles, whereas noncommunicating hydroceles develop increased scrotal fluid from abnormal intrinsic scrotal fluid shifts.
