Have you seen a continence nurse? There are lots of (quite yucky but not as yucky as being housebound and messy) things like serious pads and disposable car seat protector thingies and semi-waterproof knickers that could help you over the next little while as you sort it out.
Are you having trouble emptying completely as well - there may be options to help there too, so that you can go to the loo and know that you will be right for a while afterwards.
