Safety and Efficacy of Eraser Laser Enucleation of the Prostate: Preliminary Report

Abstract

Eraser laser prostate enucleation and bipolar transurethral prostate resection were equally safe and effective to relieve bladder outflow obstruction and lower urinary tract symptoms. This laser technique has the advantage of less blood loss, and shorter catheter time and hospital stay.

Bipolar transurethral vaporization: a superior procedure in benign prostatic hyperplasia: a prospective randomized comparison with bipolar TURP

“…Also fluid absorption betides in the bipolar TURP and volume overload may be problematic in patients with severe cardio-pulmonic disorders (23,27,31,36). In the last decade, laser energy has been applied with high safety and efficacy for vaporization or enucleation of hypertrophic large volume prostate (6,9,(11)(12)(13)(40)(41)(42). But laser therapy may be accompanied with the use of multiple techniques and different wattage, technical complexity, prolonged operative time, higher applied energy and re-operation rate in the larger prostate volume cases, high cost equipment and inaccessibility in many centers (6,9,(11)(12)(13)(40)(41)(42).…”

Beside morbidity and complication, attention to other outcomes, prostate volume, anesthesia risk, patient satisfaction, cost-benefit or cost--effectiveness, learning curve, easy accessing and performing is important in the selection of preferable procedure.…”

“…Although conventional monopolar transurethral resection (TUR) of the prostate (TURP) has been applied as a gold standard surgical modality in the recent decades (6)(7)(8)(9)(10)(11)(12), but its outcomes including patient discomfort, prolonged catheterization and hospitalization durations, need to transfusion and re-admission due to hemorrhage or clot retention, high volume of irrigation fluid, electrolyte imbalance and TUR syndrome, urinary retention, urethral stricture, incontinence, retrograde ejaculation or erectile dysfunction (6)(7)(8)(13)(14)(15)(16)(17)(18)(19)(20) elicited the tendency to the use of the newer technologies such as bipolar energy or laser energy for resection, vaporization, ablation or enucleation and changing the irrigation fluid from glycine to normal saline in the endoscopic management of BPH (6,8,(13)(14)(15)(20)(21)(22)(23)(24)(25)(26).…”

Tissue Effects Resulting from Eraser Laser Enucleation of the Prostate: In vivo Investigation

“…Therefore, various lasers have been introduced as alternatives to TURP, including Nd:YAG, Ho:YAG, KTP:YAG and Tm-laser. Diode lasers have also been used for BPE treatment and recent studies have reported results comparable to TURP [2,3]. The radiation emitted by a diode has different properties based on the different wavelengths used, resulting in completely different cutting and penetration of the tissue and vessel sealing.…”

“…Our first clinical experience revealed very good cutting properties and coagulation efficiency for this particular wavelength [2]. To understand the mode of action better, we decided to investigate the effect of the Eraser diode laser on human prostate tissue.…”
