What is the name of the urinary catheter inserted directly into the bladder through the abdominal wall?

The insertion of a urinary catheter directly into the bladder through the abdominal wall is referred to as a suprapubic catheter. This type of catheter is typically used when it is necessary to bypass the urethra, which may be obstructed or injured, or in situations where long-term urinary drainage is required and the urethra is not suitable for catheterization.

Suprapubic catheters are placed surgically or with a needle, and they allow for urine to be drained from the bladder while keeping the urethra open for other purposes. This method can be more comfortable for the patient compared to urethral catheters and reduces the risk of certain urinary tract infections associated with traditional catheterization.

On the other hand, G-tubes and J-tubes are types of feeding tubes, not urinary catheters. A Foley catheter is inserted through the urethra into the bladder and is commonly used for short-term urinary drainage, but it does not involve the abdominal wall as a point of entry.
