I am 24 years old and have had kidney failure in the past. i recently had a kidney transplant 4 months ago. I went to the clinic today about a bladder infection -( cloudy, and frequent peeing) and they found protien in my urine. This is NOT usually a sign to a bladder infection and is usually a sign to abnormal kidney function. There could be a infection in the kidney or something a little more drastic. Hopefully it\'s not a huge concern which the protien content was +2 which is not alot but still a concern. Any amount of protien (unless very, very small) in urine is not a good sign and should be further checked for kidney problems.
