With proper treatment, Escherichia coli in the urine does not lead to serious complications, notes Mayo Clinic. E. coli is the leading cause of urinary tract infections, according to UCSF Medical Center. These bacteria normally live in the intestinal tract where they do not cause problems but sometimes move to the urinary tract in women. Without treatment the resulting infection sometimes advances to the kidneys where it potentially causes serious complications.
