They are used by people who are unable to drain out the urinary bladder on their own either because of a surgery, urinary incontinence and enlarged prostrate or other medical reasons.
Why is the catheter smaller than the urethra?
If the catheter is smaller than the urethra then there will be leakage of urine. However, one must keep in mind that if there is the chance of blood clots passing through the catheter or large volumes of fluid flow, following an infection or postoperative bleeding, then the catheter should be slightly larger.
Why is it important to get the right size catheter?
It is important to get the catheter sizing right. The reason is three-fold. If the FR is smaller than what is needed, then the emptying out of the bladder will take time. If the FR is too big for the urethra, then there will be difficulty and pain when inserting the catheter. A catheter size larger than required is more likely to cause trauma ...

The industry is moving to silver-coated catheters in an attempt to reduce the incidence of urinary tract infections , although there is limited evidence of efficacy. An additional problem is that Foley catheters tend to become coated over time with a biofilm that can obstruct the drainage.
How does Foley catheter work?
A Foley catheter can also be used to ripen the cervix during induction of labor. When used for this purpose, the procedure is called extra-amniotic saline infusion. In this procedure, the balloon is inserted behind the cervical wall and inflated, for example with 30-80 mL of saline. The remaining length of the catheter is pulled slightly taut and taped to the inside of the woman's leg. The inflated balloon applies pressure to the cervix as the baby's head would prior to labor, causing it to dilate. As the cervix dilates over time, the catheter is readjusted to again be slightly taut and retaped to maintain pressure. When the cervix has dilated sufficiently, the catheter drops out.
Why do people need a urinary catheter?
Indications for using a catheter include providing relief when there is urinary retention, monitoring urine output for critically ill persons , managing urination during surgery, and providing end-of-life care.

Medical uses
Indwelling urinary catheters are most commonly used to assist people who cannot urinate on their own. Indications for using a catheter include providing relief when there is urinary retention, monitoring urine output for critically ill persons, managing urination during surgery, and providing end-of-life care.
Foley catheters are used during the following situations:
Contraindications
Indwelling urinary catheters should not be used to monitor stable people who are able to urinate or for the convenience of the patient or hospital staff. Urethral trauma is the only absolute contraindication to the placement of a urinary catheter. Examination findings such as blood at the urethral meatus, or a high riding prostate necessitate a retrograde urethrogram prior to insertion.
In the United States, catheter-associated urinary tract infection is the most common type of hosp…
Adverse effects
All catheterised bladders become colonised with bacteria within 24 hours. This is not an infection and is very poorly understood by clinicians. Whilst the presence of a catheter does increase the incidence of bloodstream infections secondary to a urinary origin, there is a huge amount of unnecessary, and likely harmful, antimicrobial prescribing on the basis of detection of asymptomatic bacteriuria. The industry is moving to silver-coated catheters in an attempt to red…
