Sometimes the homeostasis of the urinary system becomes upset, making the
normal function of micturition impossible. There may be a need then for catheterization.
Health care providers must strive to make this a safe, efficient, and non-traumatic
experience for the patient.
PURPOSES OF CATHETERIZATION
There are a number of reasons why catheterization may be performed. Included
are the following:
a. Obtain a sterile urine specimen.
b. Measure the amount of residual urine in the bladder.
c. Relieve a distended bladder in the patient who is unable to void.
d. Provide continuous drainage or irrigation.
e. Administer medications such as a chemotherapeutic solution.
f. Measure the urinary output.
g. Prepare a patient for a surgical procedure or obstetrical delivery (childbirth).
h. Assist the patient following surgery.
INDICATIONS FOR CATHETERIZATION
Indications for catheterization include the following:
a. The patient's bladder is severely distended.
b. Urinary output is severely decreased.
c. There is a significant outflow obstruction.
d. The patient is in shock or pre-shock status.
e. The patient has an acute spinal cord injury.
