What type of urinary catheter remains inside a person for an extended period?

An indwelling catheter is specifically designed to remain inside a person for an extended period, often weeks or even months. This type of catheter is secured in place within the bladder, typically using a small balloon that is inflated once the catheter is inserted. This design allows for continuous drainage of urine, which is especially important for individuals who may be unable to urinate naturally or need prolonged catheterization due to medical conditions, surgery, or other health-related issues.

Indwelling catheters are commonly used in various healthcare settings, such as acute care hospitals, long-term care facilities, and during surgical procedures. They differ from intermittent catheters, which are inserted as needed and removed after each use, and from external catheters, which are applied externally and do not enter the bladder. While the term "Foley catheter" is often used interchangeably with indwelling catheters, it is actually a type of indwelling catheter; thus, the broader term is more encompassing for the purposes of identifying the correct answer.
