title: Profuse unilateral hyperhidrosis induced by urinary retention in a stroke patient.
abstract: BACKGROUND
  The diagnosis of urinary retention in stroke patients is challenging because their symptoms may be subtle, or go unnoticed. Furthermore, patients suffering from aphasia or impaired cognition often have difficulties communicating urination problems, leading to their urinary retention being overlooked.
  
  
  METHODS
  We report a 53-year-old man with bilateral pontine hemorrhage resulting in incomplete locked-in syndrome. During the patient's hospital course, he developed 3 episodes of rapid onset of profuse unilateral hyperhidrosis. All 3 episodes were found to be induced by an overly distended bladder and each time the unilateral hyperhidrosis resolved promptly after bladder drainage.
  
  
  CONCLUSIONS
  This case provides the first description of unilateral hyperhidrosis as a manifestation of urinary retention in a stroke patient. It is important for clinicians to recognize this condition so that appropriate management can be implemented in time to prevent potential detrusor injury and renal impairment caused by bladder overdistension.
