METHODS: Eighty cases who had undergone renal transplantation were randomly divided into 2 groups:① preemptive therapy group (n=40), who were given ganciclovir (GCV, 250 mg/d) once at least 1 CMVPP65 positive cell per 2.0×105 PBL till the antigenemia became negative.② Control group (n=40), who were given universal twoweekprophylaxis with GCV (250 mg/d) beginning at the 3rd week after transplantation.
