Supra pubic catheter

Question 1

What is a supra-pubic catheter (SPC)?

Answer 1

A supra-pubic catheter (SPC) is a type of urinary catheter inserted surgically through the lower abdomen, above the pubic bone, into the bladder. It is used for bladder drainage when patients cannot void urine naturally or need a long-term solution.

Question 2

How is a supra-pubic catheter different from a traditional urethral catheter?

Answer 2

Unlike a traditional urethral catheter, which is inserted through the urethra, an SPC is placed directly into the bladder via a small incision in the abdominal wall.

Question 3

What are some common indications for SPC insertion?

Answer 3

Common indications for SPC insertion include:

1. Chronic Urinary Retention – Conditions like neurogenic bladder, prostate enlargement, or urethral stricture.
2. Urethral Trauma or Obstruction – When the urethra is damaged or obstructed.
3. Post-Surgical or Post-Traumatic Use – After certain pelvic surgeries or trauma.
4. Neurological Disorders – Such as multiple sclerosis, spinal cord injury, or stroke.
5. Incontinence – Severe incontinence or medical need for bladder management.
6. Prolonged Bladder Drainage – A longer-term alternative to urethral catheters

Question 4

When is an SPC used in cases of chronic urinary retention?

Answer 4

SPC is used in patients with chronic urinary retention who are unable to void urine due to conditions like neurogenic bladder, prostate enlargement, or urethral stricture.

Question 5

Why might an SPC be used in cases of urethral trauma or obstruction?

Answer 5

An SPC offers an alternative route for drainage when the urethra is damaged or obstructed, making urethral catheterization difficult or impossible.

Question 6

In what post-surgical or post-traumatic situations is an SPC indicated?
