Which catheter is surgically inserted directly into the bladder?

• A. Suprapubic catheter
• B. External catheter
• C. Foley catheter
• D. None of the above

Answer: (A)

The idea being tested is the route by which a catheter reaches the bladder. A suprapubic catheter is placed through the lower abdomen into the bladder, often via a small surgical or percutaneous incision, so urine drains directly from the bladder without going through the urethra. This distinguishes it from a Foley catheter, which is inserted through the urethra into the bladder, and from an external catheter, which sits outside the body and does not enter the bladder. So when the catheter must be introduced directly into the bladder via the abdominal wall, the suprapubic route is used.
