Catheterization is basically the process of inserting a catheter into a body cavity to allow body fluids to pass out of the body. Catheterization procedure is of two types – cardiac catheterization (where a catheter is inserted into the heart through a vein in the arm to diagnose heart problems) and urinary catheterization (where a catheter is inserted into the bladder through the urethra to drain out urine from the body).

A urinary catheter is a flexible, hollow tube that is inserted into the bladder to help drain out the urine. The various kind of urinary catheters available are; Rubber Catheter, Silicone Catheter and Plastic or PVC catheter.You may need a catheter because you have urinary incontinence (leakage), urinary retention (not being able to urinate), prostate problems, or surgery that made it necessary.

Urinary catheter uses

There are many medical reasons behind the use of a urinary catheter. A doctor usually recommends the use of a urinary catheter in the following medical conditions;

  •  When a patient is suffering from urinary incontinence
  •  A patient has a problem of urine retention
  •  Blocked urine flow owing to kidney or bladder stones, blood clots in the urine and severe enlargement of    the   prostate gland
  •  Prostate gland surgery
  •  Surgery in the genital area like hysterectomy
  • To drain the bladder during childbirth, if epidural anesthetic is administered
  • To drain the bladder prior to any surgery, like – womb, ovaries or bowels
  • To directly administer medicine into the bladder during chemotherapy for bladder cancer
  • Spinal cord injury
  • Dementia
  • Spina bifida
Urinary Catheter Types:

Urinary catheters are of three types – indwelling catheter, external catheters and intermittent catheters.

Indwelling Catheters:

Indwelling catheter also referred to as urethral, foley or suprapubic catheter is the type of catheter which is left inside the bladder for a week, month or as needed and recommended by the doctor. In foley catheterization, a catheter is inserted in the bladder through the urethra, while in suprapubic catheter a tube is inserted in the bladder through an incision made in the belly instead of the urethra. The catheter is made to stay inside the bladder with the help of a tiny inflated balloon. This balloon can be deflated at the time of removal of the catheter.

External Catheters:

External catheters are convenient and suitable to be used only in men owing to the shape of the catheter. In this type of catheter a condom like device covers the head of the penis and a tube leads from the condom device to a drainage bag. This type of catheter carries a lower risk of infection and can be daily changed.

Intermittent catheter or short term catheter:

This type of catheter is used especially during medical procedure for a short time and should be removed after the procedure is completed. External catheters are often referred to as in and out catheter by healthcare professionals. External catheters are relatively safe to use and don’t cause any infections or other health problems.

Female Catheterization:

Female catheterization is different from male catheterization, since female urethra is shorter in length than male urethra. There are three types of female intermittent catheters, namely;

Straight catheter

Female intermittent straight catheters are uncoated and need to be lubricated before it can be inserted.

Hydrophilic catheter

Hydrophilic catheter are similar to straight catheters, the only difference being it comes with coating that is activated by water making it slippery and ready to use.

Closed system catheter

Closed system catheters are pre – lubricated and contain a self contained collection bag.

Dialysis Catheter

A dialysis catheter is a catheter used to swap blood from a haemodialysis machine to a patient. The dialysis catheter has two openings one red which is for the arterial opening to draw blood out of your body to the haemodialysis machine and a blue opening that returns the cleaned blood to the body.
