Reversible bladder denervation in acute polyradiculitis.

A case of reversible bladder denervation in acute polyradiculitis is presented, in which both motor and sensory bladder involvement could be demonstrated using cystometry and denervation-hypersensitivity testing. Attention is drawn to the differential diagnosis to cauda equina syndromes of other etiologies, and treatment with prompt catheter drainage is emphasized. Catheter removal should be guided by disappearance of denervation supersensitivity, and residual urine control by non-invasive methods is recommended.
