Abstract

Hematoporphyrin derivatives (HPD) argon laser phototherapy has been carried out since 1986 for 37 cases of superficial transitional cell bladder tumor. A modified high power interstitial (contact) irradiation of argon ion laser was employed to destroy the visible tumor and a cylindrical optical fiber was used for whole bladder mucosal irradiation to lessen recurrence. Follow up cystoscopic examination 1 - 3 years after treatment revealed complete remission of the growth in all the patients. Recurrence was found by cystoscopy in 9 cases (24.4%). The procedure was claimed to be a simple, safe, and effective new means for the management of superficial transitional cell tumors of the bladder. Satisfactory results have been achieved.
