The presence of persistent hypertension in cases of congenital polycystic kidney has been a disputed point in the literature. Various investigators1 have called attention to the high incidence of hypertension associated with this condition. In 1928, Bell and Clawson,2 after a review of the literature and a study of eight cases, concluded: "The available information is strongly against the view that congenital cystic disease of the kidneys is accompanied by persistent hypertension." In 1914, Veil3 studied three cases in which a definite diagnosis of polycystic kidney had been made at a clinical examination. The patients were women, aged between 42 and 50.
