Indwelling catheters are inserted into the bladder via the urethra and if properly fitted, will not leave any residue inside the body. The term indwelling refers to the fact that the catheter remains in place until you remove it or a doctor has inserted a tube into your bladder via your urethra. Indwelling urinary catheters are frequently used in patients with severe obstructive pulmonary disease (COPD), in that it allows doctors to deliver medicine more rapidly. Indwelling urinary catheters have also been used as a way of saving babies from premature birth, by reducing the risk of death during childbirth due to insufficient blood circulation.
Indwelling catheters are a common part of medical procedures today, and a wide range of different materials are available for their use. An indwelling catheter is a small catheter, which lives in the bladder. Often a nurse or other medical professional insert an indwelling catheters into the bladder via the urethra, sometimes through a small hole in abdomen. From here, the catheter can then be attached to a plastic tube (or through another tube if it's a smaller device) which delivers medication into the body. The catheter, as it functions, will allow you to remove urine regularly and hence maintain a regular flow of urine so that you do not have to worry about infection.
Catheters fitted with a small flexible plastic tube known as a stopper may allow you to insert two single-action catheters or three dual-action catheters. One of the most common types of catheters today is the rubber catheter. These are used particularly where the patient has not been trained to urinate by pushing against the base of the penis or using other methods. When inserted into your bladder, the stopper will seal around the bulb and the urine will start to flow into the tube which will be removed by the nurses or other medical staff when they collect it from the back.
