intravenous pyelogram
radiographic study of the kidney and ureters in which dye is injected into a vein to define structures more clearly
pneumocystography
radiographic study of the urinary bladder after air has been placed in the bladder via a urethral catheter
radiography
imaging of internal structures that is created by exposing specialized film to x-rays
scout film
a plain x-ray made without contrast material
retrograde pyelogram
radiographic study of the kidney and ureters in which contrast material is placed directly into the urinary bladder
urinalysis
examination of the urine components
urinary catheterization
insertion of a tube through the urethra into the urinary bladder
