However, if ondistention a pelvis will hold from 15 to 25 , the questionarises are we dealing with a pelvis the normal capacity ofwhich is from 5 to 10 , but which is now dilated to twoor three times its normal capacity, or with an unusuallylarge normal pelvis? The existence of a small amount of 100 PYELOGRAPHY residual urine in the pelvis might easily be confused with therapid flow of hypersecretion. In order, therefore, to demon-strate the exact condition present, the outline of a well-distended pelvis, as seen in the pyelogram, may be of moredefinite diagnostic value than any other data. Probably the first deviation from the normal to be notedin the pyelogram with early hydronephrosis is a flattening.
