Urinary Disorders and Marfan Syndrome: A Series of 4 Cases.

Marfan syndrome is a genetic disease responsible for causing cardiovascular, eye and musculoskeletal damages. Urinary disorders are not common. We present 4 cases of chronic urinary tract symptoms, with 2 different pathophysiological processes. Three patients presented with spinal cord infarct following aortic dissection surgery. They were affected by an overactive bladder with detrusor overactivity and detrusor-sphincter dyssynergia. One patient complained of voiding dysfunction, possibly related to dural ectasia. Although a rare outcome, urinary disorders may appear in Marfan syndrome, by the occurrence of surgical complications in aortic surgery or possibility of sacral nerve root compression. If so, medical care is necessary to prevent uro-nephrological complications.
