Abstract
Diagnosis of phenacetin-induced renal disease is difficult; the physician should routinely question the patient regarding phenacetin intake.
Any patient with a urinary abnormality who has a history of long-term phenacetin ingestion should have intensive and prolonged antibacterial therapy.
If organisms are cultured from the urine, sensitivity tests will determine appropriate chemotherapy.
Prognosis depends on the stage at which the disease is diagnosed.
