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 or surgeries. 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 care is essential to prevent infections and complications. Healthcare providers typically monitor the catheter's function and the patient's comfort throughout its use.
