The capacity of a hydronephrotic sac can be accuratelydetermined by noting the amount of collargol solution it takesto fill the sac and this is confirmed by the outline as shown in thecollargol plate. (See Figures IV, II, V.) 5th. Tumor growths may be often recognized by the irregularoutline of the pelvis. (See Figures V, VI.)
