A 16 deg. wedge pad for urography.
With the patient supine the long axis of the kidney has an average 16 deg. (SD 5,8 deg.) distal ventral inclination to the horizontal table top plane. A 100 cm long wedge shaped pad with a 16 deg. angle to be placed under the patient's shoulders and back during urography to bring the long axis of the kidney parallel to the horizontal plane is described. This method gives simultaneous good visualization of both the upper and lower outlines of the kidneys on a single tomographic cut.
