A hernia is an opening thru which something escapes into. In an inguinal hernia is the bowel which descends into the canal that leads to the scrotum. Classic hernia repairs are done In open fashion and there is no space left. When done laparoscopically the cavity occupied by the contents is still there, the opening protected by a mesh. Gravity and fluid from surgery collects into that space producing a.fluid collection, an iatrogenic hydrocele. Very common and mostly painless. When symptomatic and/persistent aspiration usually resolves the issue since there is no further fluid collection expected. Urologists unfamiliar with this sequela usually recommend removal of the pseudohydrocele. I warned my patients about this issue and have aspirated a few with no recurrence. Fluid is usually yellowish liquid and easily aspirated when seen early.
