I used Conveen sheath and bag system at end of my RT where I had some long journeys and no facilities as it was difficult for me to hold urine for long. This worked quite well as I got the appropriately sized stocking in addition to the belt to support the bag which has a valve to empty. I found I needed this as there is a tendency for the bag to slip down, particularly if you move energetically. I contacted Coveen who kindly arranged to send me a range of their products free of charge, but don't know if they still do this. However, if that included the sheaths, only a few were provided and I arranged through my GP for appropriately sized ones to be provided at a local pharmacy. It is highly recommended to cut back/shave pubic hair in the area to avoid being pulled. I only used this in emergency because you don't want to use it as a norm because that way, control is not being exercised. (Sadly, for the small number of men that never regain control, the Conveen system can become the norm).
