I do think it would be a good idea to have some disposable catheters the 14″ or 16″. I used the 14″ and they work very good and helped with the inflammation. If you have any urinary infection or the inflammation of the prostate you will not be able to urinate and will die. Antibiotics are also needed (Ciprofloxacin. 500mg) every 12 hours for 7 days so if you can get your hands on some do it. All of this also works on women.
