1

Define KUB

Plain frontal supine radiograph of the abdomen (kidney, ureter, bladder)

2

KUB Uses

Identify stones (4+ mm)
Assess constipation in pediatric patients
Inexpensive

3

Define Intravenous Pyelogram (IVP)

X-ray done with intravenous contrast to look at the kidneys, ureters, & bladder

4

IVP Uses

Abdominal injury
Bladder & kidney infections
Hematuria
Flank pain
Tumors

5

Risk of an IVP

Allergic reaction

6

Process of IVP

Patient will void before & after study
Series of images taken at various times to look at filtration

7

Types of Ultrasounds in Urology

Renal
Scrotal
Prostate

8

Reasons for a Renal Ultrasound

Size of kidneys
Signs of injury to the kidneys
Abnormalities present at birth
Presence of blockage or kidney stones
Complications of a UTI
Cysts or tumors

9

Reasons for a Scrotal Ultrasound

Size of testicles
Evaluate mass or lump (cystic vs. solid)
Find reason for pain
Look at blood flow to testicles
Look for location of undescended testis

10

Type of Prostate Ultrasound

Trans-Rectal Ultrasound (TRUS)

11

Reasons for a Prostate Ultrasound

Detect disorders within the prostate
Measure prostate (volume)
Help diagnose the cause of a man's infertility
Evaluate prostate nodules: needle biopsy
Placement of needles for radiation

12

Define Voiding Cystourethrogram (VCUG)

X-ray study of the bladder using fluoroscopy & contrast material

13

Reasons for a VCUG

Check for vesicoureteral reflux after a UTI
Bladder obstruction
Abnormal urination with very high pressure within the bladder
Incomplete bladder emptying

14

Uses for a Retrograde Urethrogram (RUG)

Diagnose urethral pathology from trauma or urethral strictures
Done for pre-op & post-op reconstruction of the urethra
Help identify urethral diverticulum & fistulas

15

CT Scans for Renal Stones

Gold standard to detect stones
No contrast dye
Detects all types of stones
Gives shape, size, & location of stone

16

Drawbacks of CT Scans for Renal Stones

Radiation exposure
Cost

17

Uses for CT IVP

Evaluate collecting system, ureters, & bladder
Causes of hematuria
Identify renal tumors better than CT w/o contrast

18

CT IVP

Use IV contrast dye

19

Drawbacks of CT IVP

Radiation exposure
Cost (2 scans)
Allergy to contrast dyes
Renal disease

20

Radionuclide Imaging (Renal Scan)

Looks at blood supply, function, & excretion of urine from kidney

21

Radiopharmaceuticals Used in Radionuclide Imaging (Renal Scan)

DTPA
MAG3

22

Benefits of Renal Scans

Provides information unattainable by other imagining
Helps with diagnosis & management

23

Risks of Renal Scans

Low radiation exposure
Allergic reactions

24

Prostate MRI

Mainly for cancer
Determine extent of cancer spread
Helps in planning radiotherapy for prostate cancer
