På nuværende tidspunkt begynder 980 mm diodelaseren at blive brugt til behandling af BPH5. Få rapporter har beskrevet relaterede kliniske undersøgelser. Sammenlignet med effekten af TURP i behandlingen af BPH har mange undersøgelser vist, at DiLEP forårsager mindre blodtab, opnår bedre vandladningsfunktion og har kortere kateterretentionstider 9,13,14,15.
<p c...

Sammenlignet med traditionel transuretral resektion af prostata (TURP) er laseroperationer gradvist blevet mere populære på grund af deres bedre patienttolerance, lavere mængder intraoperativt blodtab, effektivitet og kortere postoperativ restitution 4,5.
I de senere år har de hurtigst voksende teknikker involveret brugen af lasere med forskellige bølgelængder. På nuværende tidspunkt kan mange typer lasere med forskellige egenskaber bruges til at fuldføre prostataenukleation. Siden diodelaseren blev godkendt af den amerikanske FDA til prostatahyperplasi i 2007, er dens anvendelse gradvist steget til behandling af BPH på grund af dens enestående skæreevne og hæmostaseeffekt6. Laserbølgelængden bestemmer graden af absorption af vand og hæmoglobin. En diodelaser med en bølgelængde på 980 nm giver den højeste kombinerede absorptionshastighed af vand og hæmoglobin. Vævsgennemtrængningsevnen er 0,5 mm, og den kan producere koagulationseffekter i dybere væv, hvilket gør, at den har en meget god vævsablations- og hæmostaseevne 7,8.
Mange forskningscentre er begyndt at bruge DiLEP til behandling af godartet prostatahyperplasi. I praksis har traditionel DiLEP en længere indlæringskurve og giver ingen åbenlyse fordele i forbindelse med beskyttelse mod urinsfinkter9. Baseret på ovenstående årsager blev traditionel DiLEP modificeret i vores center for at forbedre værdien af diodelaserbehandling hos patienter med BPH.

enucleation of the prostate for the treatment of benign prostatic hyperplasia using a 980 nm diode laser

I den aldrende mandlige befolkning er forekomsten af nedre urinvejssymptomer (LUTS) forårsaget af godartet prostatahyperplasi (BPH) et almindeligt problem. Her introducerer vi en ny teknik kaldet 980 nm diodelaserenukleation (DiLEP) til behandling af BPH1. Diodelasere kan absorbere både vand og hæmoglobin på samme tid, så de er gode til skæring og hæmostase2. Diodelaseren blev godkendt af FDA i 2007 og er blevet brugt til behandling af BPH på grund af dens effektive skære- og hæmostaseeffekt3. DiLEP præsenterer flere fordele i forhold til andre teknikker, såsom TURP, HoLEP og PVP. Under proceduren definerer vi grænsen for en prostata med høj volumen og adskiller den i tre lapper med en diodelaser ved at brænde to ringe og en rille (som en Amors pil). Sammenlignet med andre procedurer har mDiLEP færre intraoperative komplikationer, en kortere indlæringskurve og opnår mere vævsresektion.

I alt 40 patienter med BPH, som fik DiLEP, blev inkluderet i et af vores studier. En uafhængig stikprøve t-test blev brugt som statistisk metode. Alle patienter gennemførte operationen med succes. Næsten alle patienterne fik fjernet kateteret inden for 5 dage efter operationen (tabel 1). Alle patienter vendte tilbage til hospitalet til opfølgende undersøgelser i 1., 3. og 12. måned postoperativt. Værktøjerne International Prostate...

Enucleation of the Prostate for the Treatment of Benign Prostatic Hyperplasia Using a 980 nm Diode Laser

Her præsenterer vi en protokol for modificeret 980 nm diodelaserenukleation til behandling af godartet prostatahyperplasi i stort volumen.

Enukleation af prostata til behandling af godartet prostatahyperplasi ved hjælp af en 980 nm diodelaser

In the aging male population, the occurrence of lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH) is a common problem. ...

Lower urinary tract symptom caused by benign prosthetic hypoplasia is a common condition in older males. Our new technology, 980 diode laser enucleation, can be used to treat this condition. Diode lasers can simultaneously absorb both water and hemoglobin.Compared to other procedures, diode has fewer intra-operative complications, a shorter learning curve, and achieves a greater t-cell reception. Before beginning the procedure, confirm the availability of 980-nanometer diode laser with an 80 to 100-watt continuous power source. 30 minutes before the procedure, administer an intravenous antibiotic to the patient and have the patient lie on the operating table.When the patient is in position, use the resectoscope to observe the urethra, verumontanum, bladder neck, urethral orifices, bladder mucosa, and trabecular hyperplasia. Use the laser to make a three to four-millimeter wide circular incision in the bladder neck mucosa, and a three to four-millimeter circular incision in the proximal end of the verumontanum of the prostatic urethra mucosa. Then connect the concentric circles of the bladder neck and the apex of the prostate in the posterior urethra at 12 o'clock, and incise the left and right lobes of the bladder.Then to create the channel, locate the surgical capsule at the five and seven o'clock positions of the apex of the prostate, and the surgical capsule at the five and seven o'clock surgical capsule positions. Then connect the five and seven o'clock surgical capsule positions with the laser. At the six o'clock position of the prostate's apex, separate the median lobe from the surgical capsule from the prostate's apex to the bladder neck.For lobe enucleation, use the resectoscope to enucleate the right lobe at 6 and 12 o'clock from the apex of the prostate to the bladder neck in a counterclockwise direction. Enucleate the left lobe at 6 and 12 o'clock from the apex of the prostate to the bladder neck in a clockwise direction. Then push all of the glands into the bladder.To stop bleeding around the site, place a 50-watt laser one to three millimeters from the sites of bleeding to achieve hemostasis within the surgical area. To morcellate the enucleated prostatic tissue, use a morcellator to break the tissue into as small pieces as possible, and remove the tissue from the bladder. When all of the enucleated tissue has been removed, remove the morcellator from the urethra and gently insert a 22-French Foley catheter lubricated with lidocaine gel through the urethral orifice into the bladder cavity.Then inflate the balloon with 30 milliliters of water. In this clinical study, all 40 of the patients with benign prostatic hypoplasia who underwent diode laser enucleation successfully completed the operation, and almost all of the patients had the catheter removed within five days of the procedure. All of the patients returned to the hospital for follow-up examinations in the first, third, and 12th months postoperatively.The International Prostate Symptom Score and quality of life tools were used to screen for, rapidly diagnose, track the symptoms off, and suggest the management of the symptoms of benign prostatic hyperplasia. Compared to baseline values, the International Prostate Symptom Score and quality of life both significantly decreased at one, three, and 12 months postoperatively. The mean Qmax increased nearly threefold, and the mean post-void residual decreased nearly fourfold.Compared to the preoperative values, the prostate volume also decreased dramatically. According to the modified Clavien-Dindo Classification system, no patient had complications intraoperatively, and only four cases reported grade one postoperative complications. It's critical that the channel is created in the correct location and the manner to reduce the chance of injury to the sphincter and neck of bladder.Also, other lasers may be used. Their performance will not be as accurate as that achieved using diode light. Diode light provides a new tool for the treatment of the benign prosthetic hyperplasia and encourages the urologists to consider the physical characteristics of different lasers to improve the outcome of the procedure.
