Diabetic cystopathy is a well-recognized complication of diabetes mellitus, which usually develops in middle-aged or elderly patients with long-standing and poorly controlled disease. It may have broad spectrum clinical presentations. Patients may be asymptomatic, or have a wide variety of voiding complaints from overactive bladder and urge incontinence to decreased bladder sensation and overflow incontinence. This review focuses on pathophysiological mechanisms responsible for urologic complications of diabetes and emphasizing on recent developments in our understanding of this condition.
