What is a 3-way catheter?

Three-way catheters are catheters that end in three separate ends, usually used to treat bladder infections.

A 3-way catheter is a style of catheter that ends in three separate ends rather than a single or double tube. It is used to treat bladder infections and other conditions that require a medical professional to put something into the bladder as well as drain it. Because these catheters are a type of Foley catheter, they do not slip, they are sometimes known as 3-way Foley catheters.

3-way Foley catheters drain urine from the bladder and allow doctors to treat infections.

This type of catheter ends in three separate tubes – the middle tube has a much larger opening, while those on either side narrow and can be capped. The design was created especially for anyone who needs a bladder rinse due to blood clots or infections. To withstand the stresses of the liquid that will pass through it, the catheter is reinforced from the inside with a nylon coil. A Foley catheter is different from others in that it has a small balloon attached to the end that is inserted into the bladder. Once inserted, the balloon can be inflated so that the device remains securely in place.

Treatment for some forms of bladder cancer may involve the use of a catheter.

When performing continuous bladder irrigation (CBI), the 3-way catheter is inserted into the patient’s urethra and bladder. After the balloon is inflated, an irrigation bag filled with saline is attached to one of the narrower tubes and hung from an IV or IV rod. This allows gravity to push saline through the catheter. The saline flows through the catheter, into the bladder and out again through the other two tubes. The wider central tube allows blood clots and other substances to pass through the catheter without obstructing the overall flow.

Painful urination and blood in the urine are symptoms of a urinary tract infection, which can occur as a result of using a catheter.

A 3-way catheter can also be used to fill a patient’s bladder without having to wait for them to drink water. Using the same method, saline is introduced into the bladder using a pin while the other two remain capped. A full bladder shows up most clearly on a computed axial tomography (CAT) scan and is therefore useful when a medical professional is trying to make a diagnosis.

A urine test can be used to test for bladder infections.

Like all catheters, 3-way devices can be used in both men and women. While it has been proven in many cases to be a useful tool for people with bladder problems, catheters also carry the risk of infection. When they are left inside the bladder and urethra for days or weeks, they can irritate the tissue, become infected, or develop a “biofilm” that prevents it from draining properly. For this reason, a 3-way catheter must be replaced frequently with a new, sterile catheter for long-term drainage.
