Purpose: We evaluated the efficacy of the holmium:YAG laser for transurethr
al endoscopic prostatectomy for benign prostatic hyperplasia (BPH).
Materials and Methods: We treated 103 patients with BPH with holmium:YAG la
ser resection of the prostate. A high power holmium laser generating a maxi
mum of 60 or 81 W. was used in a pulsed mode, applying energy directly to p
rostatic tissue via a forward firing 550 mu. fiber transurethrally under di
rect vision. Treatment outcome was evaluated by the International Prostate
Symptom Score, quality of life score, maximum flow rate and post-void resid
ual urine volume. We also compared holmium laser surgery and transurethral
resection of the prostate for operative factors, such as surgical duration,
bleeding volume and catheterization time.
Results: Average symptom score, quality of life score, peak flow rate and p
ost-void residual significantly improved at 1 week, 1 month and 3 months po
stoperatively, with improvement maintained up to 36 months postoperatively
in the holmium:YAG group. Intraoperative bleeding volume was significantly
lower and catheterization time was significantly shorter for holmium:YAG th
an for transurethral prostatic resection. Use of the holmium laser caused n
o complications.
Conclusions: Because of its effectiveness and safety holmium:YAG resection
is a viable potential surgical alternative for symptomatic BPH. The holmium
:YAG laser has been verified to be useful for many purposes in urology.
