Attualmente, il laser a diodi da 980 mm sta iniziando ad essere utilizzato per il trattamento dell'IPB5. Pochi rapporti hanno descritto studi clinici correlati. Rispetto all'effetto della TURP nel trattamento dell'IPB, molti studi hanno dimostrato che DiLEP provoca una minore perdita di sangue, raggiunge una migliore funzione minzionale e ha tempi di ritenzione del catetere più brevi 9,13,14,15.</su...

Rispetto alla tradizionale resezione transuretrale della prostata (TURP), gli interventi chirurgici laser sono diventati gradualmente più popolari grazie alla loro migliore tolleranza al paziente, alla minore quantità di perdita di sangue intraoperatoria, all'efficacia e al recupero postoperatorio più breve 4,5.
Negli ultimi anni, le tecniche in più rapida crescita hanno previsto l'uso di laser di varie lunghezze d'onda. Attualmente, molti tipi di laser con caratteristiche diverse possono essere utilizzati per completare l'enucleazione della prostata. Da quando il laser a diodi è stato approvato dalla FDA statunitense per l'iperplasia prostatica nel 2007, il suo utilizzo è gradualmente aumentato nel trattamento dell'IPB grazie alla sua eccezionale capacità di taglio e all'effetto emostasi6. La lunghezza d'onda del laser determina il grado di assorbimento da parte dell'acqua e dell'emoglobina. Un laser a diodi con una lunghezza d'onda di 980 nm fornisce il più alto tasso di assorbimento combinato di acqua ed emoglobina. La capacità di penetrazione del tessuto è di 0,5 mm e può produrre effetti di coagulazione nei tessuti più profondi, il che gli conferisce un'ottima capacità di ablazione ed emostasi dei tessuti 7,8.
Molti centri di ricerca hanno iniziato ad utilizzare DiLEP per il trattamento dell'iperplasia prostatica benigna. In pratica, il DiLEP tradizionale ha una curva di apprendimento più lunga e non presenta vantaggi evidenti legati alla protezione dello sfintere urinario9. Sulla base dei motivi sopra esposti, il DiLEP tradizionale è stato modificato nel nostro centro per migliorare il valore del trattamento con laser a diodi nei pazienti con IPB.

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

Nella popolazione maschile anziana, l'insorgenza di sintomi del tratto urinario inferiore (LUTS) causati dall'iperplasia prostatica benigna (IPB) è un problema comune. Qui, introduciamo una nuova tecnica chiamata enucleazione laser a diodi a 980 nm (DiLEP) per trattare l'IPB1. I laser a diodi possono assorbire contemporaneamente sia l'acqua che l'emoglobina, quindi sono ottimi per il taglio e l'emostasi2. Il laser a diodi è stato approvato dalla FDA nel 2007 ed è stato utilizzato nel trattamento dell'IPB grazie al suo efficace effetto di taglio ed emostasi3. DiLEP presenta diversi vantaggi rispetto ad altre tecniche, come TURP, HoLEP e PVP. Durante la procedura, definiamo il confine di una prostata ad alto volume e la separiamo in tre lobi con un laser a diodi bruciando due anelli e un solco (come una freccia di Cupido). Rispetto ad altre procedure, mDiLEP ha meno complicanze intraoperatorie, una curva di apprendimento più breve e raggiunge una maggiore resezione dei tessuti.

In uno dei nostri studi sono stati inclusi un totale di 40 pazienti con IPB sottoposti a DiLEP. Come metodo statistico è stato utilizzato un t-test a campione indipendente. Tutti i pazienti hanno completato con successo l'operazione. Quasi tutti i pazienti hanno avuto il catetere rimosso entro 5 giorni dall'intervento (Tabella 1). Tutti i pazienti sono tornati in ospedale per esami di follow-up nel 1°, 3° e 12° mese dopo l'intervento. ...

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

Qui, presentiamo un protocollo per l'enucleazione laser a diodi a 980 nm modificata per il trattamento dell'iperplasia prostatica benigna di grande volume.

Enucleazione della prostata per il trattamento dell'iperplasia prostatica benigna mediante laser a diodi da 980 nm

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.
