With communicating hydroceles, simple Valsalva maneuvers probably account for the classic variation in size during day-sleep cycles. Nonetheless, with the incidence of patent processus so great, why children with clinically apparent hydroceles are relatively few remains somewhat inexplicable. Chronically increased intra-abdominal pressure (eg, as in chronic lung disease) or increased abdominal fluid production (eg, children with ventriculoperitoneal shunts) probably warrants early surgical intervention.
