Bed wetting in the teenage years can be physical and/or psychological. One of the ways we would try to determine this was by prescribing DDAVP (if there were not any issues that would prevent using it). Desmopressin (trade names: DDAVP, Stimate, Minirin) is a synthetic replacement for vasopressin, the hormone that reduces urine production. It may be taken nasally, or as a tablet. Lack of the hormone vasopressin is more common in men than in women. Typically, those that do not produce enough will "correct" by the end of puberty (19-25 years old for men). Check with your urologist about the possibility of this treatment. Best of luck.
