Twenty-four mongrel dogs of either sex weighing 21 to 34 pounds divided into 4 equal groups were subjected to intravenous pyelography and drip infusion pyelography with and without compression to study the radiographic anatomy, using sodium iothalamate 70% (w/v) solution @ 400 mg of iodine per pound of body wt. The kidneys of the dogs were bean shaped having crescentric pelvis with 5–7 pairs of pelvic diverticuli. The right kidney was less mobile. 87.5% and 70.8% radiographs taken at 5,10,15 and 20 min post-injection intervals revealed kidney and ureteral density, respectively, either equal to or greater than that of the adjoining ribs. Left ureter occupied mote medial position. Bladder appeared pear to balloon shaped with greater radiographic density than the adjoining bones on all the radiographs taken at 20 and 40 min post-injection intervals.
