An indwelling catheter is a flexible tube inserted into the bladder to drain urine. It is often used for patients who cannot urinate on their own due to medical conditions, surgeries, or injuries. The catheter remains in place for an extended period, secured by a balloon that inflates inside the bladder. These catheters can be made of various materials, such as latex or silicone, and come in different sizes. Regular monitoring and care are essential to prevent complications like infections. Healthcare providers typically manage the insertion and maintenance of the catheter to ensure patient safety and comfort.
