What is the purpose of an indwelling catheter?

An indwelling catheter is primarily used to provide continuous drainage of urine from the bladder. This type of catheter is designed to remain in place for a longer duration, allowing for consistent monitoring of urinary output, which can be critical in various clinical situations. It is commonly used in patients who are unable to void naturally due to surgery, injury, or certain medical conditions. The design of the indwelling catheter, which often includes a balloon that holds it in position within the bladder, enables effective drainage and reduces the risk of complications associated with urinary retention.

In contrast, the other options relate to different medical functions that do not apply to the role of an indwelling catheter. For example, creating an anastomosis is a surgical procedure that connects two structures, while assisting in ovulation pertains to reproductive processes, and performing suture techniques involves closing wounds or surgical incisions. None of these involve the main purpose of providing urinary drainage that is characteristic of an indwelling catheter.
