Transcript CYSTOGRAMS__LOOPOGRAMS


Purpose: evaluation of the anatomy and
physiology to the urinary bladder

Preparation:
 1) explain the procedure to the patient
 2) informed consent is required for
catheterization of pediatric patients
 3) have the patient empty his/her bladder

Sterile, disposable catheterization set

Contrast media: ionic contrast

Fluid administration set

Variety of straight and Foley catheters in
varying sizes (#14 adults, #8-10 child)
(sometimes a small infant feeding tube for
infants and toddlers)

Call nursing to perform catheterization
Take preliminary KUB scout
Set room up for fluoro
Measure any residual urine once catheter has
been placed
Connect contrast media to catheter via
catheter tubing set
Radiologist will begin to fill bladder w/ gravity
flow

Cystogram: looking at the bladder only. The
physician is not concerned about urethra, nor
ureters!

VCUG: looking at the bladder, urethra &
ureters. This exam is an extension of a
cystogram in that we take voiding imaging to
see if the contrast is refluxing up into the
ureters.

Same as the cystogram except overhead
images will be taken on a 14x17 image size to
include the kidneys, ureters & bladder.
Usually done upright.

Preliminary KUB
Inflate balloon on Foley and press against the
stoma. Do not inflate the balloon in the stoma!
Radiologist will inject contrast via the catheter
into the stoma.
Once the procedure is completed help patient
replace his/her stoma pouch.

(Full 14x17 field size to include kidneys, ureters
& bladder)

Purpose: For evaluation of urethral patency

Take preliminary image: RPO, center over the
symphysis pubis and penis (70kVp), 10 x 12
F.S.

Possible overheads:
 RPO

Purpose: Evaluation of the anatomy of the
post ileo-loop (ileo conduit)

Patient is pregnant
Same setup and consent as the standard IVU
Differences:
▪ No preliminary KUB
▪ 15 minute KUB & show to the radiologist
▪ No other images will be taken unless absolutely
necessary and ordered by the radiologist!
