[Hinman syndrome--an uncommon cause of recurrent urinary tract infections since childhood].

A 20-year-old female presented with a history of recurrent urinary tract infections, diurnal incontinence, nocturnal enuresis, and voiding difficulty. Imaging studies revealed a thick trabeculated bladder and high post-void residual urine volumes. Urodynamic evaluation demonstrated involuntary bladder contractions and no evidence of bladder outlet obstruction. A full neurological and urological workup were both unremarkable. A thorough history revealed her symptoms were initiated after prolonged and stressful potty training with multiple failed attempts. She developed a dysfunctional voiding pattern consistent with a non-neurogenic neurogenic bladder, also known as the "Hinman syndrome". Successful therapy relies primarily on behavior modification maneuvers combined with medical therapy to reduce unstable bladder contractions and alleviate bladder outlet obstruction.
