Needless to say that such a pyelogram is only ex-ceptionally permissible. Pyelography is valuable as an aid to the diagnosis of hy-dronephrosis in the following conditions: (1) Constric-tion of the ureter not permitting a ureteral catheter to enterthe pelvis. (2) Short length of catheter with return flowon overdistention. (3) Unusual length of catheter withhypersecretion. (4) In demonstrating etiologic factors. Ureteral Obstruction.—When the obstruction in theureter does not permit the catheter to enter the pelvis, itmay be impossible to demonstrat
