I had a kidney stone removed 3 days ago. I don't know what procedure they used, all I know it that I now have a green pipe thingy in my penis. Every time I urinate ( which is like 20 times a day) it feels like I'm passing blades and I get a sharp pain in my kidney. There is also blood present that I can see, but not every time I urinate, mostly in the mornings and later in the evenings. I must admit that the pain is getting better everyday. My question is, are all these symptoms normal and when can I take the pipe thingy out?
