Nelaton Catheter

When the bladder is unable to empty on its own, doctors often recommend the use of a catheter. Catheter sizes are commonly color-coded, with size 8 being blue, size 10 black, size 12 white, size 14 green, size 16 orange, and size 18 red. The procedure of using a catheter is known as catheterization.

A Nelaton catheter, also referred to as an intermittent catheter, is a thin, hollow tube made of soft plastic that is inserted into the bladder through the urethra to drain urine. These catheters come in various colors, each indicating a specific size. The Nelaton catheter is generally used for intermittent catheterization to periodically empty the bladder.
