4

hilum

a depression of the medial border of the kidney

5

ureter

one of two muscular tubes (16 to 18 inches long) lined with mucous membrane. they carry urine in peristaltic waves from the kidneys to the urinary bladder

renal angiography

xray examination (with contrast) of the blood vessels of the kidney

retrograde pyelogram (RP)

xray imaging of the renal pelvis and ureters after injection of contrast through a urinary catheter into the ureters from the bladder
