Abstract

Transurethral laser destruction using contact Nd:YAG laser (TULD) was performed on 96 occasions in 72 patients from February 1984 to December 1987. For the purpose of cure, TULD was undertaken on 59 occasions in 37 patients with primary bladder cancer. In the 59 occasions, usefulness of the TULD was evaluated. The cancers were classfied and staged in accordance with the Japanese Urological Association. The usefulness of the TULD was judged by surgeons with criteria as follows: degree of difficulty of manipulation, degree of destruction of the cancers, and bleeding during the TULD. Features of the cancers, for which the TULD was judged as useful, were summarized as follows: 1. On cystoscopical findings, the form of the cancer was superficial, the number of cancers were under the number of four and the sizes of the cancers were under 3 cm in diameter. 2. On pathological findings, the grade of the cancers reached grade II and the stage of the cancers reached stage T1.
