What is a catheter and what is it used for?

If you’re wondering what a catheter is or what it’s used for, then buckle up buttercup because I’m about to give you an education. This isn’t just some fancy tube that people stick in places where the sun don’t shine, this device has actual medical purpose – although I wouldn’t recommend bringing one out at parties. In layman’s terms, a catheter is a thin tube made of soft plastic or rubber that can be placed in your body to help drain fluids, allow access for medications or surgery.

What are the Different Types of Catheters?

There are various types of catheters, each with its own shape and function.

Indwelling Catheters

Indwelling or Foley catheters typically stay inside your bladder over long periods. They usually have two parts: one part stays outside of the body and contains some valves and tubes to manage drainage; while the other end passes through the urethra (the opening on top of male genitalia) into the urinary bladder itself.

Condom/External Catheters

Also known as “Texas” external (or “Uri-drain” if being extra fancy!), these type uses adhesive tapes instead of insertion directly in any particular area unlike indwelling. It works by attaching a receiving container onto penis shaft where urine flows through tubing connected from thereon until contained completely.

Suprapubic Catheters

These materials come helpful when patients cannot empty their bladders naturally either due post-surgery scenario related issues arising which leave little choice but introduce an external source; hence usage entails inserting via surgical procedure anywhere around pubic bone region making way straight into bladder cavity so sealing off infection prone risk areas without having been contaminated further down below such as rectum area!

The Uses Of A Catheter:

Now that we’ve covered different types let’s delve deep into possible reasons why one may need this medical device.

Urinary Retention

Certain conditions such as Prostate gland enlargement, neurological disorders such as Multiple Sclerosis (MS) can lead to retention of urine which tends to build up over time inside bladder causing blockages. In that case, a catheter is put in place so that none overflow happens and also helps prevent kidney damage due pressure exertion.


In some surgeries like gynecological & colorectal they use an indwelling catheter during the surgery because the bladder needs draining until it’s finished. Once completed stitches must heal before removal at appropriate healthcare provider’ recommendation timings schedule / criteria guidelines followed religiously without fail otherwise adverse effects set after prolonged usage outstay their welcome bringing more pain/discomfort than relief along with other complications arising (coughs UTI’s coughs)

The Risks Associated With Catheters:

While I’m all for innovation in medicine we gotta take into account certain downsides attached unless you want be under permanent self insert mode!

Pain and discomfort

Inserting one of these little beauties isn’t pleasant but neither is living long term post-transaction; hence blood stains/prints come part present after multiple tries being made at right angles & directions resulting near muscle tear or unnecessary forceful entry rashness happening.. ouch! not ideal indeed especially when dealing with sensitive areas ! It’s necessary either way as longer stay periods could result on damaging surrounding skin making it easily prone inflammation.

Potential for infections

Bacteria generally loves thriving alongside body fluids no matter what form they are; let alone a pouch filled half way where stagnant fluid ages rapidly increasing odds of infection attacking/surviving against defense mechanisms further multiplied since sticking anywhere within urethra/toes make notorious germ buddies spreading faster stretching till kidneys!!! precautions require routine changing hygiene care empowering frequent hand washing rituals besides monitoring sodium levels regularly so not prolonging problematic infections surfacing!

Bladder Injury

When inserted, one needs accurate judgment and steady hands otherwise things can be quite dicey in some rare cases. Fluid may get into other areas surrounding urinary tract causing inflammation leading to sepsis if not handled by skilled personnel; hence demonstrate utmost care containing potential blowback effects residing with protract improper insertion.


At the end of the day a catheter’s usage is prescribed individually based on need & degree of treatment required weighing out pros/cons before proceeding ahead which shouldn’t dread when professional opinion assistance comes-in helpful as blessings guidance provide robust financial security / insurance coverage options beside recovery times scaling underway!
