Intermittent catheterisation
Intermittent catheterisation (IC) is a way to empty the bladder by inserting a catheter at set times. It can be used for a short period or as a daily routine for life. IC is often the preferred method for medical bladder emptying. It can be done by the patient or a caregiver at home.
People with neurogenic bladder, such as from spinal cord injury, spina bifida, or multiple sclerosis, may need catheterisation to empty the bladder. People with non-neurogenic issues, like an enlarged prostate, urethral strictures, or urinary retention after surgery, may also need catheterisation.
Keeping a catheter in all the time can cause problems like urinary tract infections, urethral narrowing, or male infertility. Intermittent catheterisation at regular times helps avoid many of these problems and keeps bladder pressure low.
It isn’t clear which catheter designs or techniques best prevent infections or are most cost effective.
Catheters come in different designs. They are longer for men and shorter for women. The catheter is inserted into the urethra by the patient or a caregiver. Urine can be directed into a toilet, or into a measuring jug if the amount needs to be checked. Wheelchair users may use a jug to collect urine more easily.
