A catheter is a general term for a tube that's fitted into the body. A urinary catheter is a tube that's fitted into the bladder to drain urine. Multiple types of urinary catheters are used for a variety of conditions, and the right catheter for one person isn't inescapably right for another person. A case's condition that makes the catheter necessary frequently guides the decision of what type of catheter is necessary.

Types

Straight catheter:- This is a rubbery tube fitted into the urethra and through to the bladder. It's removed when the bladder has drained fully. A straight catheter doesn't remain in place for an extended period It's intended to be used only formerly. Still, for some cases who must use this type intermittently throughout the day at home, a catheter may be castrated and reused.

Suprapubic catheter:- This type of catheter isn't fitted into the urethra. Rather, it's placed through a low abdominal gash directly into the bladder. A suprapubic catheter is generally used after certain types of surgery (similar to prostate surgery) that disrupt the normal inflow of urine. It frequently remains in place for days to weeks, or it may be used permanently.

Condom catheter:- This type of catheter, used only with males, isn't fitted into the urethra; rather, it's placed on the penis much like a condom would be. It's worn throughout the day and collects urine in an attached bag during occurrences of incontinence.

Foley Catheter:- A Foley catheter, also known as an indwelling catheter, remains in place for an extended period. The catheter is attached to a collection bag where urine drains and is voided periodically. The tip of a Foley catheter is fitted into the urethra and through to the bladder, where it's kept in place with a small exaggerated balloon.

Coudé catheter:- This is another type of indwelling catheter, like the Foley. The difference between them is that the tip of the Coudé catheter has a slight wind, which helps thread the catheter through the urethra when a case has an inhibition, similar to an enlarged prostate.

Purpose of a Urinary Catheter

A urinary catheter is used when the case is unfit to control their bladder because of illness, incontinence, a condition that makes urination delicate (similar to a spinal cord injury), or unconsciousness.

For illustration, a catheter is frequently placed on the morning of certain surgeries because the case won't be conscious of the procedure. Without the catheter, the case might urinate during the procedure and potentially pollute the sterile field, or the bladder may come overinflated with urine during a long procedure.
To help infections, catheters are used only when necessary. In rehabilitated cases, ferocious care cases generally have a catheter in place for longer than a day. For other cases who have one in place, the catheter is removed as soon as they're conscious or well enough to urinate singly.

Urinary retention is an issue where the bladder fails to clear fully. Depending on the inflexibility of the issue, a temporary catheter, called a straight catheter, may be used to drain the bladder.

Pitfalls of a Urinary Catheter

The primary threat of short-term catheterization is a urinary tract infection. In addition, the urethra (the tube that carries urine out of the bladder) can come bothered. The skin girding the insertion point might also be injured and should be audited regularly for signs of breakdown.

In rare cases, a urinary tract infection can lead to urosepsis, a systemic infection that can be veritably serious.

Placement of a Urinary Catheter

A catheter is placed using a sterile fashion and sterile lubricant to help the infection. Utmost catheters are fitted into the urethra, also gently threaded through the urethra into the bladder.5

Junking of a Urinary Catheter

A catheter is generally veritably easy tore move. However, the balloon is deflated, also the catheter is gently pulled to remove it from the body If there's a balloon at the tip of the catheter. The process is generally effortless unless there's vexation present in the urinary tract. However, a topical drug can be used to numb the area, If the process is painful.

Urinary Catheter Care at Home

Still, catheter care can be performed in the shower or bath, if you're minding for an indwelling catheter at home. After gently drawing your genital area as you typically would, the catheter tube can be gently gutted with a washcloth and mild cleaner. Take care not to haul or pull on the catheter, or try to push the catheter further into the body, as this can beget vexation. Be sure to wash the cleaner off fully.

A catheter and the attached drainage bag should only be touched after washing your hands with cleanser and water, this can help with infection.

A Word from Veritably well

A urinary catheter is common in the sanatorium setting, but recent exploration and guidelines encourage sanatorium staff to remove catheters as snappily as is nicely possible. This is done to help urinary tract infections and to drop the threat of side goods similar to difficulty urinating.

Urinary catheters are infrequently allowed to stay in place for convenience like they formerly were, and are generally only allowed when necessary for the case's health.
