I have urine that smells fishy. i have protein and blood in urine dipstick. i also have swollen ankles. what could be the cause?

Proteinuria: You need to see a nephrologist as soon as possible. Protein in the urine is a symptom, not a diagnosis. Have a 24 hour urine collection for creatinine clearance and protein, have blood taken to see if you diabetes or high levels of cholesterol and a renal ultrasound to see if you and the doctor can arrive at a diagnosis for the cause of your proteinuria. You may need diuretics to control the edema.

Nephrotic syndrome?: Protein and blood in the urine could suggest kidney disease and ankle swelling may mean a significant amount of protein in the urine which should be treated. See a nephrologist who can help diagnose the problem and offer specific treatment if in fact it is a kidney issue. The longer this goes without treatment, the greater the risk for permanent kidney damage. Good luck!
