KTP laser versus transurethral resection: Early results of a randomized trial

Abstract

Background and Purpose: Many technologies have been mooted as equal to transurethral resection of the prostate (TURP) without gaining widespread acceptance because of the lack of randomized trials. The Greenlight® laser system (Laserscope, San Jose, Ca.), an 80 W system for photovaporization of the prostate (PVP), was compared with TURP in such a trial. Patients and Methods: A series of 120 patients was randomized to undergo TURP or PVP after evaluation, which was repeated at 1, 3, 6, and 12 months after treatment. Irrigation use, length of catherization (LOC), length of hospital stay (LOS), postvoiding residual volume, sexual function, blood loss, cost, and operative time also were assessed..
