I have had a suprapubic catheter for over a year and had an indwelling one before that and had to use conveens before that.....you get the idea. I have always used leg bags with that lot, but in April this year my local Community Nurse (who changes my S/P catheter) told me about 'Belly Bags'. They are similar to bum bags, but they fit on your belly using a belt. I have been using them ever since and they are FANTASTIC! They have a 2 litre capacity, whereas most leg bags for use during the day only have a 750 ml capacity. You don't need to attach a leg bag to them over night and they only need to be replaced every 4 weeks instead of weekly. They empty using a simple valve which is similar to those on leg bags and are very discreet unless you use very tight clothing. I wear loose jogging bottoms most of the time and they don't show up at all. I would imagine they are only going to be useful to people who can walk or can at least stand at a toilet for a few seconds as those of you who are wheelchair bound would need to use a jug or something similar to empty it. I just wish they had been available a few years ago. A tremendous and very simple device.
