This pamphlet contains an interesting discussion of certain phases of renal physiology and anatomy largely related to changes in the outline of the renal pelvis, calyxes and the ureter as visualized by urography. A brief review of the embryology, anatomy and physiology of the excretory portions of the kidney is followed by a discussion of certain pathological influences. The author then describes the various methods of urographic investigations of the renal pelvis and ureter, which include urokymography, uroscopy, serial films and urography, both excretory and retrograde.
The contents are summarized as follows:
The outline of the renal pelvis and calyxes and the ureter during the various phases of systole and diastole is described. Systolic contraction occurs on the average every 10 seconds. This period is affected by renal secretion, the reaction resulting from medication, the degree of bladder filling and the influence of respiration and of body position, as well
