The causes of white urine can be as follows.
Celiac disease and steaturia: celiac disease is seen in filariasis or perirenal lymphatic obstruction; steaturia is seen in fatty crush injuries, fractures and nephrotic syndrome.
Crystalluria: precipitation of urates, phosphates and carbonates, forming urine crystals, mostly a normal physiological phenomenon.
Pusuria: purulent infections of the urinary system (e.g. cystitis, renal tuberculosis, prostatitis, pyelonephritis and other diseases).
