摘要

Abstract: Seventy patients with 316 tumors of urinary bladder have been treated by high power gold vapor laser with HPD photodynamic therapy in this hospital. All cases were histopathologically diagnosed as transitional cell carcinoma, T1-T3 stage and all are recurrent ones. HPD was administered intravenously 48 hours before the treatment (5 mg per kg of patient weight) and irrigated into bladder 2 to 4 hours (2.5 mg per kg of patient weight) before the treatment. The power calculated was 70.8 - 509.6 mw/cm per pulse. The pulse energy was 0.5 mJ per pulse and the repetition rate was 6000 - 9000 Hz. Both the tumors and whole bladder were irradiated through the fiber inserted in the bladder by cystoscope. The results of a follow-up from 4 to 46 months are as follows: cured 54 (77.14%); good effect 12 (17.14%); improved 4 (5.7%). Regrowth occurred in only 8 cases (11.43%) between 3 to 14 months.!4
