Abstract
This type of destructive coagulating energy appears to be an attractive method for control and eradiction of superficial or multiple bladder tumors. Control of depth of destruction of tissue offers a significant advantage over electrocautery. Epithelial regrowth is rapid and morphologically normal. We noted that the on-time for the RSP mode of operation was longer than for the cw mode, but coagulation necrosis and edema were similar. With the ability of the rapid superpulsed laser to vaporize comparable volumes of tissue with a lower average power, it is apparent that by using comparable power densities between the two modes, the resulting necrosis and edema would be reduced, and the on-time would be reduced yielding a smaller zone of coagulation necrosis and edema.
