As a Urologist, I must advise you to send me the reports, for a detailed view of the urine, blood and scan reports.  By reading your question, I must opine, that all reports are surely suggestive of a kidney problem, with less function. Uric acid, can also go up Creatinine is an indicator of kidney function. When kidney function decreases, the creatinine will go up accordingly, and vice versa. If kidneys are affected, the size on a scan will also show decrease. You can send the reports for an expert opinion, to me. Chat Doctor.  Manga. </s>
