TREATMENT MANUAL VAPORIZATION OF BENIGN OR CANCEROUS PROSTATE

Clinical Application:
HPLAS diode laser for vaporization of benign or cancerous prostate treatment from
GIGAALASER

Clinic Explanation:
The aim of diode laser ablation is resect a channel which would allow or improve urine
flow, instead of removing maximal amount of prostate tissue.
The HPLAS 980nm highly absorption in water and hemoglobin. It provide good ablation
and coagulation effect.

Related Keywords:
Benign prostate, Transurethral resection of prostate, Urinary retention, diode lasers

Medical device:
HPLAS 980nm 150W
Mode: CW mode
Operation power: 90-125W

Accessories:

HPLAS from gigaalaser, Side fiber, Cystoscope

Operation procedure:
1. General or local anesthesia, before the procedure, the patient receive parenteral
antiemetic, antibiotic garamycine 240mg,diazepam 10mg and extended release
oxycodone 10mg.

2. Connecting the accessories, lock the fiber in the resectoscope mechanism system,
then opening the device and setting parameters. Out put power 90w-125w.

3. Press the foot switch and fiber movement move forward and backward to ablate the
prostate.

4. The procedure is about to terminate when is estimated prostatic fossa was already
wide enough, which would allow or improve urine flow. Lase the total energy ranged
from 78kj~142kj.



Advantage:
According to those data near-infrared wavelength of 980nm, with its distinctive position in
the middle of all important parameters seem to be most balanced and attractive.
1. Compare to Nd-yag
HPLAS 4 times higher absorption in water. Lower penetration depth, less risk.


2. Compare to KTP
Much better ablation with at least same coagulation
Cheaper both laser system and fiber

3. Compare to holmium laser
Diode:220v power supply, compact size,
Holiminu:expensive(morcelator and laser), difficult, time-consuming

4 Compare to traditional TRUP
No need perfusion, catheter tension, higher safety and comfort

Notice:
* Laser fiber needs very delicate handling and regular cleaning through tissue
brushing,not removing during the procedure,otherwise laser fiber breaks.
* Careful and limited ablation near colliculus is mandatory otherwise incontinence may
occur.
