question: My husband believe he is or has passed a kidney stone - he had some burning and small amounts of blood while urinating earlier today - he now has a good flow and some burning - no blood. He is 79 yrs. olds, and has heart and lung disease - comundin (SP) and a daily 81mg aspirin due to a heart valve replacement 20 years ago. He did have prostrate cancer during the past 20 years and underwent radiation - and PSA is very low now. Is it necessary to contact his Urologist in the morning since things seems much better?
