[Etiology and pathogenesis of primary hydrocele in children].
The serous-wall of the typical, non-communicating, idiopathic hydrocele of the child presents with a lympho-static oedema, whose protein-containing fluid is pressed transmesothelially into the lumen. The cause must be seen in the lymph-drainage of the tunica vaginalis testis which follows the obliteration. The above described etiological-pathogenical concept gives the more or less empirical therapeutic-methods a rational basis.
