Can Dopamine Depletion at DAT Scan in a Non Parkinson Patient be the Cause a Refractory Overactive Bladder?

Abstract

We report here the first case of treatment of idiopathic refractory overactive bladder with dopamine. A female patient consulted for urge incontinence. Management included all recommended treatments without success. DAT scan was finally performed showing clear reduction in dopamine secretion without diagnosis of any neurological condition. Patient started dopamine treatment. At 1 month, patient described persistence of mild urgency and frequency but complete resolution of urge incontinence. At 3 months patient was completely dry with only persistence of mild frequency. Functional imaging and central nervous system target might represent new ways of managing idiopathic overactive bladder.
