Bladder tumors are one of the common urological tumors, and the incidence of bladder cancer is on the 12 th of cancerous diseases worldwide, and the incidence of bladder cancer is on the 6 th of male diseases. Transurethral cystectomy is the gold standard for treating non-muscle invasive bladder cancer, and is widely applied due to the advantages of minimal invasion, few complications, quick postoperative recovery and the like, while laser is the most common resection means. In the case of a small bladder tumor and pedicle, laser ablation may be performed directly from the base. If the tumor body is large, even if the pedicle is small, it is not desirable to excise directly from the fundus to avoid bladder perforation, and the excises should be performed sequentially from the top of the tumor.
In the process of operation, after the tumor is cut off from the whole basal block, the tumor body drifts in the bladder cavity filled with flushing fluid, so that the bladder tumor can be implanted and metastasized, and the surgical tumor-free principle is violated. More seriously, when the tumor is too large and can not be excised from the whole base, and needs to be excised from the top part of the tumor layer by layer, the risk of tumor implantation and metastasis is higher, and the tumor with too large volume needs to be taken out after being crushed.
