The big thing with them is if the hose gets kinked ,with causes the catheter to slowly exceed it's ability giving you a blow out with urine going everywhere, you always have to have a new catheter hose and bag setup with you ,ready to go ,just like carrying a diaper bag ,the containment bags are either strapped to your thigh or calf and I could max the largest bag out in one flood ,so be prepared to buy one size larger pants to accomodate the bag , the calf bag is a little easier to empty just put your leg up on the toilet and open the drain valve , they do have fancy ones for us disabled guys that are obscenely expensive that have a large hose you pull out of your pant leg that has a pump on it that gives you a urine super soaker you have a belt that has the off on button for emptying the bag, since I intermittent strait cath I have a large night drain bag usually hidden under my wheelchair and one attached yo my bag those will hold 2000 ML before needing to be emptied, sometimes i get run down and don't want to be bothered and will put a foley in attach to the drain bag and call it done (Foley catheters in the real world quickly turn you urethra at the head of your penis into chop meat , you really have to keep reapplying lube to try and keep that at bay) ,do not use petroleum jelly because it will degrade and destroy your drainage tube which is rubber. This applies to all tubes no matter the style of catheter they are all rubber.
You generally will be allotted two drainage bags per month so once a day usually in the evening you have to rinse your tubes and bag with a vinegar solution to cut down on odor and kill off bacteria.
The weakest link on this type of system is the leg bag straps they are latex rubber ,so they pinch and bind ,a and obviously you can never get any kind of good position were it will stat put thanks to our friend gravity as the bag fills it slides down your leg ,when I was able bodied at times I had to wear a bag and no matter what you tried eventually it would fall off and hit the ground if you were lucky it was only an embarrassment if today wasnt your day it would fall the wrong way and you would step on it sending 500 ML of liquid gold everywhere.
So just like any artificial method of continence it has its weakness and points of failure ,one of the bigger ones people dont consider is getting the right size ,if you get too big a condom (as in prophalactic) you can fake it and make it work , with a condom cathter there is very little margin for error ( if you call or email Coloplast they will be happy to get a script from your doc and send you a variety sample pack to try them and find the right comfortable and functional size, this actually applies to all there products, i'm sure other companies have some kind of program but Coloplast in my opinion has the best products in the industry so its been many years since i dealt with anyone else. They are quite generous before i started just getting the large night drain bags they have an all in one sterile telescoping hydrophylic catheter with drain bag attached,You could use it and the little bag has an easy tear away corner to then drain before chucking it , my insurance won't pay for them a case would last several years ,but the insurance industry has some bullshit regulations one of them is they will not pay for two different styles of catheter at the same time ? ,however I could get samples every six or eight months that would cover all the times I actually needed an all in one style product .I actually just got a new style softer coude catheter that is pocket size and is a dry hydrophylic ( which means there is no sterile water to spill out of the package if you cath and there is no garbage can you can put it back in the package and shove it back in your pocket till you get to a can , alot lower profile than the speedicath which comes in a 17 inch rigid foil package with liquid and is a bright green and white package , the new one is grey and will easily fit in your pocket , so it's alot more discrete and easy to carry in a pocket rather than a diaper bag , not everyone totes them around )
