Holmium:YAG Laser Treatment of Recurrent Superficial Bladder Carcinoma: Initial Clinical Experience

Abstract

To review our initial experience with the holmium laser in patients with recurrent superficial bladder cancer. We treated 41 patients having 71 recurrent superficial transitional-cell tumors of the bladder between December 1994 and September 1997 using the holmium:YAG laser under local anesthesia. The laser treatment was carried out as a part of the follow-up flexible cystoscopy protocol, and topical anesthesia was used. The mean follow-up was 14 months (range 3-33 months). There were 13 recurrent tumors in the treated area and 38 recurrences in the untreated areas. Of interest, a subgroup of 10 patients were treated before 1994 with cystodiathermy and later on with the holmium:YAG laser at various times during their follow-up. The local recurrence rate with cystodiathermy was 32% compared with 10% after laser treatment (P = 0.39). A questionnaire study of 33 patients showed complete satisfaction with the treatment. Only 2 (6%) elected to have a further procedure under general anesthesia. In the series, 83% scored their pain as 2 or less of 10 on a visual analog scale. The absence of complications, high patient satisfaction, and ability to be used in the outpatient setting make the holmium:YAG laser an attractive alternative in the treatment of recurrent superficial cancer of the bladder.
