Fecaluria is the presence of feces in the urine.
Definition
Fecaluria is the mixture of feces and urine that is passed from the urethra due to a fistula between the intestinal tract and bladder. A fistula is an abnormal passage that leads from an abscess or hollow organ to the body surface or from one hollow organ to another. It may be surgically created to permit the passage of fluids or secretions.
