Abstract
|
|
|
Laser CHRP (coagulation and hemostatic resection of the prostate) is a new acceptable treatment modality for benign prostatic hyperplasia.
A total of 14 patients with symptomatic bladder outlet obstruction the to benign prostatic hyperplasia was entered into a prospective trial of laser prostatectomy performed with the rightangle firing neodymium: YAG laser fiber and the contact tip
firing
neodymium: YAG laser fiber at 60 watts power setting. Mean estimated prostatic weight was 36.3%gm. Six patients (43%) were in urinary retention requiring catheterization before treatment. Mean energy delivery was 34,442 joules (range 25,360 to
45,000)
with a mean operative time of 41 minutes. Efficacy of treatment was assessed at 1, 6 and 12 months postoperatively by Madsen symptom scores, peak urinary flow rates and urinary flow rate 8.6cc per second, and mean ultrasonic assesment of
prostatic
volume 36.3gm. At 1 year postoperatively mean symptom score was 6.1, mean peak urinary flow rate was 18.3cc per second and mean ultrasonic assesment of prostatic volume was 26.4 gm. One patient required dretreatment for residual tissue. There was
one
bladder neck contracture requiring incision.
