In brief: By symptoms
Bladder infections usually cause painful, frequent urination with or without low back pain.
Patients with kidney may have the above but will typically be quite ill with fever, nausea/vomitting and flank (upper back toward the side) pain. Both will usually have an abnormal urine test.
