Self removal of urinary catheter following a Robotic Assisted Radical Prostatectomy (RARP)

What is a trial without catheter?

A trial without catheter [TWOC] is when your urinary catheter (a tube that passes through your waterpipe; urethra and drains urine from your bladder) is removed. It is important that you are able to pass urine sufficiently to have a successful trial without catheter at home.
This leaflet describes the TWOC process at home having recently undergone urological surgery. It is a simple procedure which allows you to remove the catheter in your own environment and prevents you having to come back to the Hospital.
