Q

Fluids are absorbed through the ______.

______ is created in the ______.

_______ hold it and turn it into ____ and send it to the ______.

The _______ connects to the _______ which sends _____ to the ______.

A

Fluids are absorbed through the MEDULLA.

URINE is created in the CALYCES.

CALYCES hold it and turn it into URINE and send it to the RENAL PELVIS.

The RENAL PELVIS connects to the URETERS which sends URINE to the BLADDER.

Q

How is an IVP/IVU performed?

A

Performed by injecting an iodinated contrast agent (Optiray) through an IV and taking films to visualize the kidneys, ureters, and bladder

17
Q

What films are taken for a IVP/IVU?

A
  • Preliminary scout KUB
  • 3 minute delay of kidneys after injection of contrast
  • 5 minute delay of kidneys
  • 15 minute delay KUB and both posterior obliques rotated 30° (LPO and RPO)
  • Post-void KUB
18
Q

How is a cystogram performed?

A

Performed by introducing 200-400mL of contrast (Cysto-Conray) through a urethral catheter under fluoroscopy in order to demonstrate the bladder walls, the distal ureters, and the urethra

19
Q

What films are taken for a cystogram?

A
  • AP preliminary scout
  • AP, RPO, and LPO when bladder is full
  • Lateral
  • Post-void bladder spot
20
Q

How is a voiding cystourethrogram (VCU) performed?

When does the radiologist exam the anatomy via fluoroscopy?

In what position are females examined vs males?

A
  • An examination of the bladder and urethra performed by using contrast (Cysto-Conray) introduced into the body via urethral catheter.
  • Before, during, and after voiding
  • Females - AP position Males - RPO position
21
Q

All patients ___ and older, with ___ or with known _____must have _______ drawn prior to injection of ________ in order to check ________ to ensure patient safety.

High ____ signify improper function of _____, meaning ____ could cause _____ failure.

A

All patients 65 and older, with DIABETES or with known RENAL DISEASE must have BLOOD LABS drawn prior to injection of IODINATED CONTRAST in order to check CREATINE to ensure patient safety.

High CREATINE LEVELS signify improper function of KIDNEYS, meaning CONTRAST could cause RENAL failure.

22
Q

Creatine of ____or ____ = safe to recieve contrast

A

Creatine of 1.6 or LESS = safe to recieve contrast

23
Q

Name and describe possible reactions to contrast

A
  • Dyspnea - difficulty breathing
  • Angina - chest pain
  • Nausea or vomiting
  • Hives associated with severe itching
  • Arrhythmia - irregular heartbeat
  • Vertigo - dizziness
24
Q

Define bradycardia and tachycardia

A
  • Bradycardia - slow heartbeat
  • Tachycardia - fast heartbeat
25
Q

Name 5 pathological conditions of the urinary tract

A
  • Hydronephrosis
  • Carcinoma
  • Polycystic kidney disease
  • Pheochromocytoma
  • Vesicoureteral reflux
26
Q

Define hydronephrosis

A

Distention of the renal pelvis and calyces with urine

27
Q

Define carcinoma

A

Malignant new growth composed of epithelial cells - bladder or renal cell (in kidney)

28
Q

Define polycystic kidney disease

A

Massive enlargement of the kidney with the formation of many cysts

29
Q

Define pheochromocytoma

A

A rare, benign tumor of the adrenal glands that causes hypertension

30
Q

Define vesicoureteral reflux

A

Backward flow of urine from bladder into ureters
