A suprapubic catheter is best described as:

• A. An indwelling urinary catheter surgically inserted directly into the bladder.
• B. An external catheter placed over the penis.
• C. A Foley catheter inserted through the urethra.
• D. A catheter used only for irrigation.

Answer: (A)

This question is about where the urinary catheter enters the bladder and how that placement defines the type. A suprapubic catheter is a tube that drains urine directly from the bladder through the lower abdomen, above the pubic bone, bypassing the urethra. It’s typically placed surgically or with a minimally invasive approach and remains indwelling with the collection bag outside the body. This distinction matters because it contrasts with a catheter that goes through the urethra into the bladder (a urethral, or Foley-type, catheter) and with external, noninvasive drainage devices that sit on the skin rather than enter the bladder.

So the description fits best because it emphasizes entry into the bladder via the abdominal wall rather than through the urethra, which is what sets suprapubic catheters apart. The other options describe methods that either stay outside the bladder, go through the urethra, or refer to irrigation use rather than placement.
