Auriculotherapy in the prevention of postoperative urinary retention in patients with thoracotomy and thoracic epidural analgesia: A randomized, double-blinded trial.

Background: Thoracic epidural analgesia is associated with a high rate of postoperative urine retention (POUR). Auriculotherapy can reduce visceral dysfunction and can be helpful in anesthesiology and pain control. The aim of this study was to test the efficacy of preoperative auriculotherapy to decrease the occurrence of POUR.
