My 80 year dad old has pinkish urine began yesterday Tuesday morning urine was dark and when seen in urinal bag was dark and reddis appearance , he had some discharge of mucus on and off days before . and also today this morning the urine is a little darker the urine appears pink like grapefruits but a littl yellowish going over the reds pinks ect. he as an Appointmen to see a Dr. tomorrow afternoon ! but I am not sure if he can wait perhaps 911 ? , or could he wait until tomorrow ? he does not have other symptoms some pain he said in his penis temp was ok for now , he has had some minor temp fluctuations over several months 99 ect but then went down . BP is normal , had a UTI some months ago last year , he used only diapers back then now using condom catheters for night use only due to the problems his urination causes like skin related problems diapers do not work for him , so I got some condom catheters from Amazon and ebay for him to use at night only .daytime he uses diapers
