Retrograde pyelography

Retrograde pyelography combines the use of a long, flexible viewing tube called a cystoscope with contrast x-rays to visualize the kidneys and ureters. The cystoscope is inserted through the urethra into the bladder; fiberoptic cables permit direct visual inspection of these structures. A catheter is then threaded through the scope so that a contrast dye can be infused directly into the ureters to delineate them on x-ray films. Retrograde pyelography is most often performed when intravenous pyelography produces inconclusive results, or when it cannot be performed because of impaired kidney function or another reason.

신기능이 나빠서 IVP하기 어려울때, IVP검사 결과가 애매할때

DMSA(APN의 진단에 매우 sensitive)

radionuclide

emits a type of radioactivity called gamma ray

injection into a vein

DMSA is used because it builds up concentrate in the kidneys

areas of the target organ or tissue which emit lots of gamma rays may be shown as red spots ('hot spots')

목적 : to check the structure of the kidneys, their size and shape

children who have had urinary tract infections

areas of the kidney are working well and any areas of scarring

Scarring can be caused by a condition in which urine travels back from the bladder to the kidneys. This is called vesico-ureteric reflux

also look for reduced blood supply to the kidneys.

DMSA does not attach itself to areas of the kidneys that are damaged.

monitor any changes to inflammation of the kidneys.
