Objective:To assess the efficacy of chlorophyl lderivative（CPD4）-Photodynamic therapy（PDT）in preventing postoperative recurrence of the in filtrativecancer of the urinary bladder-Methods:32 patients were treated with CPD4-PDT postoperationally to prevent therecurrence of can cerall of which being followedup.Results:There currenc erate was42.1%inT2 tumors and 69.2%inT3 tumors（P＜0.05）,and the survival period without tumor has been 19.8±14.8months in T2 tumors,and 22.67±19.72months in T3 tumors（P＞0.05）.There was verysignificant difference inrecurrent rate between grade I and gradeⅡ、Ⅲpatients（0%and66.7%,P<0.001）.ConcIusion:CPD4-PDT is a safe and effectiv emeasureto prevent the recurrence in infiltrative bladder cancer after operation.
