I Had Prostate Cancer 15 Years Ago And Had My

I had prostate cancer 15 years ago and had my prostate removed. About 6 years ago my PSA number was starting to climb and I had two months of radiation. Since then my PSA has been real low. The problem was that the radiation caused scar tissue damage in my urethea (sp) tube. DR. Kurt McCammon went in and opened up the tube back last October. The urine flow was a lot better. The last few days my flow has been very week and my urine comes out at a angle. It seems like there might be a slight blockage close to the end of my penis. I also have a history of kidney stones. I wonder if this could be a stone lodged close to the end of the penis or do you think that my tube is closing up again?
