The urethral catheterization is the method of inserting a tube (hereinafter “catheter”) through the urethra and drawing off your urine through a catheter.
The page which tells about self-urethral catheterization is the best accessed page in the piroweb site.
I wonder this is because you got some troubles on passing urine and want to have information to solve them.
It seems there are many people who cannot pass their water well and have difficulty to handle a catheter, or people who are wondering what sort of catheter to use. Therefore, in this page, I would like to show you how to do self-urination, some catheters I am using now, and ideas that I thought up for passing water for your reference.
