This article studies a contrast between 204 cases of enuresis cured by laser acupuncture-point irradiation and 78 cases cured by medicine treatment of meclofenox-ine. The full recovery rate for laser treatment was 45.09% and the total effective rate was 89.22%, while the full recovery rate for meclofenoxine treatment was 33.3% and the total effective rate was 70.5%. There is a very remarkable difference beween the two treatments (P <0.001).The problem of response produced after laser irradiation is stressed. 97. 79% of the patients had the response effect within six irradiations.
