Self catheterisation is a simple procedure where you pass a catheter regularly into the bladder to assist in the drainage of urine.
It can be performed when normal voiding is not possible, and to relieve the retention of urine.
The bladder must be completely emptied, regularly and should never have more than 400 - 450 mls in it.
You will be instructed on how many times a day you need to perform ISC
The size of the catheter used is usually 14-16 gauge.
