CONGENITAL LARGE PELVISWith a congenital solitary or asymmetric kidney, theincrease in the size and capacity of the pelvis is usuallycommensurate with that of the kidney. In Fig. 294, al-though the renal pelvis is unusually large, the outlines ofthe calyces and papillae are normal. The capacity of thepelvis was approximately 22 , as ascertained by the over-distention method. The normal terminal irregularities, 310 PYELOGRAPHY the outline of the major calyces, and the shape of the truepelvis would exclude the possibility of any hydronephrosisbeing present. Not infrequently one kidney is found to be unusuallylarge and without any apparent pathologic reason to explainit. In such cases the size of the pelvis is usually not com-mensurate with that of the kidney. Where a kidney becomesincreased in size because of destruction of the other kidney,
