This case study describes the treatment of a 13-year-old boy for enuresis using hypnosis. The referring psychiatrist specifically requested hypnosis after physical causes had been eliminated and previous behavioural interventions had not resulted in a successful outcome. Intervention was based around that described by Kohen (1990) and Olness and Kohen (1996). Promising progress was shown over the three sessions. Issues associated with the intervention are discussed.
