Patients will be identified and recruited in the hospital ward. The patients who are planned to go home with the catheter will be provided with the patient information leaflet about his study. They will be given 6 hours to decide if they want to participate in this study. Those patients who agree to participate will be asked to sign a written informed consent. A computer-generated randomisation will be carried out. They will be given a contact number of the urology nurse in case they have any problems or if they want to ask any questions before attending TWOC clinic.
