[Use of Nd:YAG laser and flexible cystoscope in outpatient treatment of recurrent superficial bladder tumors].

Nd:YAG laser irradiation and flexible cystoscopy were used in the outpatient management of 16 cases (21 sessions) with superficial bladder tumors. Irradiation of tumors was accomplished in all cases except 3 in which the visual field was affected by bleeding after the cup biopsy of tumors. Tumors at the bladder neck were easily irradiated through the flexible cystoscope. No tumor recurred at or near the previously irradiated site. This method provided a safe and cost-effective means to treat superficial bladder tumors in selected cases.
