Urinary retention secondary to Landry-Guillain-Barré syndrome.

We report on 2 patients who presented with voiding abnormalities and were found to have the Landry-Guillain-Barré syndrome. Urodynamic evaluation documented a motor paralytic bladder with denervation of the periurethral striated muscle in 1 case. The other patient recovered before denervation could be confirmed by urodynamic study. Although a motor paralytic bladder is anticipated, based on the pathophysiology of the Landry-Guillain-Barré syndrome, it has not been documented previously in the literature.
