Abstract:
Objective To investigate the effect of electrovaporization on prostatic tissue structure in vivo. Methods 26 cases of benign prostatic hyperplasia underwent electrovaporization of prostatic tissue,the surface area of the vaporized prostatic tissue and the depth at the central area being observed with light microscope and electron microscope. Results The vaporizing effect on tissue with pure cut current were stronger than that with pure coagulative current, the greater the output power the stronger the vaporizing effect.6 millimeter under the vaporized surface caused by pure coagulative current still revealed some histological alterations of injury,while these histological alterations in pure cut current electrovaporization was less. Conclusions These findings may have implications that in transurethral electrovaporization of prostate,injury to the adjacent or deep tissues should be avoided as much as possible.
