A congenitally cystic kidney sometimes attains anenormous size, so large indeed as seriously to impede labour,and in many cases embryotomy has been necessary in orderto enable delivery to be effected. In a large proportion ofinstances in which the foetus comes away without difficultyit is still-born and often malformed; such conditions asanencephalia, club-foot, and spina bifida are often associated 588 GTSTS with congenital cystic disease of tlie kidneys. Minor degreesof the affection are not incomjDatible with life, and several in-stances are known in vdiich such kidneys have been found inadult individuals. Although this condition of kidney is very common andspecimens illustrating it exist in many pathological museums,Ave know very little concerning the early stages.

Virchow regarded the cj^sts as dilatationsof the uriniefrous tubules in consequence of the absence of arenal pelvis.

A very remarkable case came under mynotice in which a child born at full term, but with greatdifficulty on account of the large size of its belly, was foundto have an imperforate urethra, a large dilated left ureter,and a hydronephrotic left kidney. The opposite kidney wasa typical exampl
