What hurts from kidney stones for men?

It hurts to pass them through the long narrow urethra. (like a woman giving birth)

There may be a little pain when it is passed through the urethra but normally not that much. The pain from a kidney stone comes when it travels from the kidney to the bladder in a tube called the ureter this tube is smaller and thinner than the urethra. The pain can be caused if it is a jagged stone by it scraping on the sides of the ureter but mostly it is the result of spasms in the ureter as your body is trying to push the stone out.
