Development of TUR-BT device for en bloc resection

Abstract

TURBT(TransUrethral Resection of Bladder Tumor) is now popular surgical treatment for bladder tumor, but devices currently used in this operation have two problems; one is that because bladder tumor tissue is cut into several pieces in TURBT with the devices, there is a risk of dissemination of tumor, and the other is that they increase a risk to damage normal tissue. In this research, we proposed a new TURBT device which enables en bloc resection in low inner pressure of bladder, and then we developed a prototype of the device and evaluation experiment was performed.
