Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Usually this is result of some food and drinks which affect urine colour,žIf blue pigment gets into urine, the color is often green because the blue mixes with the yellow urochrome that s naturally present. It s not an everyday occurrence, but there are case reports of many common medications causing green — or bluish-green — urine, including the anesthetic propofol, the stomach acid drugs The discoloration is a harmless side effect. Asparagus sometimes adds a greenish tinge that s also perfectly harmless. But green urine can be a sign of a urinary tract infection or a bacterial infection that has gotten into the blood (bacteremia). So, if you have pain or fever you should see urologist. Hope I have answered your query. Let me know if I can assist you further.
