[A case of olfactory hallucination with adult enuresis].

A 22-year-old man was referred to us complaining of enuresis. The excretory urogram and cystogram were almost normal. Spina bifida was not present. The results of the urodynamic examination including uroflowmetry, cystometry, urethral pressure profile, electromyogram and sensory threshold of external urethral sphincter were within normal limits. Amitriptyline hydrochloride and flavoxate hydrochloride showed no effects. Because we found a positive spike wave on the electroencephalogram, the patient was referred to a psychopathologist, and was diagnosed as being in the early stage of schizophrenia. He complained of enuresis as his olfactive hallucination of urine. Psychopathological treatment for 1 year and 2 months resulted in disappearance of his complaining of enuresis.
