A Brief Overview Of Foley Catheter

A Foley catheter is nothing but a flexible tube that medical professionals use for the ailing patients who cannot move or are recommended least movement. It passes through the urethra and into the bladder for drainage of the urine.  It is named after Frederic Foley who, in the year 1929, produced the original design. It happens to be one of the most used indwelling urinary catheters.

Mechanism of Foley Catheters

The tube consists of two disjointed lumens or channels running down its length. One lumen that is open at both ends drains the urine into the collection bag. The other one connects to a balloon on the inside tip and has a valve on the outside end.

Sterile water is used to inflate the balloon when it is inside the bladder to prevent from slipping out. Foley catheters are usually manufactured using coated natural latex or silicon. Coatings include silicon elastomer or hydrogelor PTFE. The different materials decide whether the catheter is suitable for a 3 month or 28 day indwelling duration.

You must keep in mind that Foley catheters should only be used when indicated. This is because there is an enhanced risk of catheter associated urinary tract infection and other adverse effects with its usage.

Medical Usages of Foley Catheters

In the emergency department, in-dwelling catheters are mostly used for assisting people who cannot urinate. The primary indications for using a catheter include a number of things like monitoring urine output for critically ill people, managing urination during a surgery, providing relief when there is urinary retention and providing end of life care.

These are primarily used for the situations listed below:

  • Foley catheters are mandatory to be used in patients who are under coma
  • These are suggested for the patients who are sedated or anaesthetized for the surgery or other medical care
  • These are also recommended for patients whose prostrate is enlarged to such an extent that urine flow is cut off from the bladder
  • The Foley catheters are also recommended for patients who are suffering from involuntary urination or leakage of urine
  • Doctors also recommend these to patients after urethral surgeries and ureterectomy
  • The patients who are unable to use urinals or standard toilet facilities due to physical injury are also prescribed Foley catheters
  • Patients suffering from urinary retention can also use Foley catheters
  • In fact, physicians also recommend the usage of Foley catheters for patients who have undergone genital injury or before and after hysterectomy
  • Before and after cesarean section, patients are advised to use Foley catheters
  • Foley catheters are also suggested for patients with kidney disease whose urine output must be measured precisely and constantly
  • Patients who cannot control their bladder or have fibromyalgia are also prescribed with this
