One of the main goals of this site is to try very hard to separate fact from fiction. Here is one more opportunity do do just that while also pointing you in the direction of another source of information (hey, it’s at least instructive to get information from a variety of sources). This particular article is from healthcarearticles101.com, which has easy-to-understand and follow advice. This one is about caring for your suprapubic catheter (if you don’t know what a suprapubic catheter is, see our post What Is A Suprapubic Catheter?). It has good advice and nothing that is going to harm you. But at least one of the suggestions has been identified as not having any evidence to support that it helps prevent urinary tract infection in people who wear indwelling catheters. That would be the advice about washing your drainage bag with soap (vinegar is also frequently suggested). Rinsing it with water (but not hot water, which could damage a bag, depending on what type it is) is sufficient. The study behind this is referenced in our article Urinary Tract Infection and Catheter Care.
The other information is sound though. Check it out here: https://www.healtharticles101.com/suprapubic-catheter-care/
