tdnjam, I am sorry to hear about
your situation. I was near fully incontinent for a year and went thru a dozen diapers a day. Pads and shields just didn't hold enough. Early on I started using external catheters. My best choice was /www.amazon.com/Freedom-Clear-Advantage-Aloe-Vera/dp/B00XTBSX56/ref=sr_1_sc_2_s_it?s=hpc&ie=UTF8&qid=1514985064&sr=1-2-spell&keywords=external+catheters+ffeedom+silicone+aloe
If the link doesn't work they are Freedom Advantage Silicone w/Aloe. They're a buck or two each and last a couple days. The best leg bags are Rusch 1000ml also around two buck each. Clamps didn't work for me at all, but I would go a day or two a week with diapers to allow little Dicky to air out.
Now I have the AUS. It's been six months or so and still becoming accustomed to it, but life is definitely much easier now. I'm guessing that you are probably not a candidate for the sling. Good luck with whatever you decide to do. Both the icons under my name should work if you'd like more info.
