Hello, I am post op by 1yr ... interestingly in my 9th month of post op I began having brownish urine. I have had this colour of urine exactly 5 times including this morning I do have a small kidney stone that is apparently too small to " zap " - I have no other symptoms of back pain or abdominal pain or dehydration as I am drinking the recommended amount of Water and more on top Does anyone else have this sporatic brownish or even light tea coloured urine ?? Thanks tcm
