i was diagnosed in March with stage 3b CKD, GFR 34. I had not noticed too many changes since then until about a week ago, when my urine suddenly changed from bright yellow to completely colorless. I haven't seen my nephrologist since my diagnosis, but have an appointment coming up soon. I intend to tell her aboout this, but in the meantime my question is, is this something significant? Has anyone else experienced this or know what it means?
