<s>[INST] Hi, may I answer your health queries right now ?   I have had blood in my urine for the past six weeks, now traces of ketones. I have had major pain in back. It is not kidney stones, and I have had frequent utis. The urologist I went to looked in my bladder and said everything is fine. The pain and the blood in urine could be from anything. In the meantime Im taking lots of pain meds to deal with the pain. [/INST] Dear patient Renal stone is common cause of back pain and hematuria. Next cause is bladder since you have history of frequent cystitis it may be the cause. If both are normal then source of hematuria lies in kidney or ureter, or rarely it can be systemic. This needs further investigation, and you need to consult expert urologist. Ct scan of abdomen and MVP are next possible investigations. All the best. </s>
