It 590 CYSTS is, however, quite certain tliat a precisely similar change ismet with in adults, and, what is also remarkable, it is veryfrequently associated with a similar change in the liver(see p. 566). The available facts indicate that a moderateamount of cystic change in the kidneys is not incompatibleAvith life, but as the disease advances the secreting tissue ofthe organs is slowly but surely destroyed, and in due courseuraemia supervenes and the patient Fig. 315.—Localized cystic disease of the kidney. {After Edmunds.) There is reason to believe that this cystic change may belimited to part of a kidne}^. Edmunds described a speci-men (Fig. 315) which he removed from a girl of 18 years, inwhich an encapsuled tumour projected into one of thecalyces of the kidney. It had a diameter of 6 cm., and wascomposed of a congeries of cysts lined with cubical epi-thelium. The large cyst connected Avith the side of the bladder CONGENITAL CYSTIC KIDNEY 591 represented in Fig. 314 had a capacity of 300 ; it isa dilated ureter. Such a condition is often mistaken for abifid bladder. Assuming that the congenital cystic kidney is due topressure leading to dilatation of the uriniferous tubules, weare met by a difficulty in dealing with the specimen, Fig. 314 :
