Laser coagulation prostatectomy has evolved into an accepted option fo
r the management of bladder outlet obstruction secondary to benign pro
static hyperplasia. Clinical results document the safety and efficacy
of this operation. Rapidly expanding clinical experience and basic res
earch efforts in recent years have provided a scientific foundation an
d an improved qualitative understanding of the laser-tissue interactio
ns during Nd:YAG laser coagulation of the prostate. Today, truly quant
itative laser dosimetry is becoming available to guide the operative a
pproaches to laser prostatectomy with the increasing variety of Nd:YAG
delivery systems. The development of laser coagulation prostatectomy
is traced to the present, and accumulated clinical experience and labo
ratory data are incorporated into a rational approach to operative and
perioperative patient management utilizing this technology.
