Abstract

Neodymium-Yag (Nd:YAG) laser irradiation for superficial bladder cancer is a valuable and safe treatment modality. The local recurrence rate is significantly reduced as compared to transurethral resection (TUR) alone (2.6 % versus 14.3 %). Remote recurrences can also significantly be reduced in solitary and multiple tumors if biopsies of the tumor are avoided. We state that the macroscopic appearance of a tumor is sufficiently reliable since only 0.67 % of the pathology proven Ti tumors were understaged macroscopically. The recurrence free interval for solitary tumors after Nd:YAG laser irradiation alone without biopsy was 19.i months as compared to i6 months after TUR with adjuvant intravesical instilations and in multiple tumors i3.6 months for Nd YAG laser irradiation alone without biopsies as compared to iO.4 months after TUR.
