PURPOSE: To compare the efficacy, safety, Patient Global Impression of Improvement (PGI-I), and complications rates after 180-W GreenLight laser (180-W GL laser) standard and anatomical photoselective vaporization (sPVP and aPVP). METHODS: Within a multi-institutional database, we identified patients who underwent sPVP or aPVP to relief BPH symptoms. IPSS, Q max, and prostate-specific antigen (PSA) were measured at baseline and during the follow-up. PGI-I score as well as early and late complications were recorded at follow-up visits...

Density functional theory calculations are employed to study the mechanism of photoselective catalytic reduction of 4-bromobenzaldehyde (4-BBA) in acetonitrile and in ethanol solvents. A totally relaxed Ti3O9H6 cluster model is proposed to represent titanium dioxide (TiO2) surfaces. The reduction selectivity of an adsorbed 4-BBA molecule on Ti3O9H6 has been investigated. Owing to the difference in the proton and H atom donating capabilities between explicit CH3CN and C2H5OH solvent molecules, the photocatalytic reduction of 4-BBA is the debromination process in acetonitrile, whereas in ethanol it is the carbonyl reduction process...

BACKGROUND: The learning curve for photoselective vaporisation of the prostate (PVP) has never been assessed accurately. OBJECTIVE: To compare 180-W GreenLight XPS PVP learning curves for three surgeons with different levels of surgical experience and different institutional backgrounds. DESIGN, SETTING, AND PARTICIPANTS: A multicentre retrospective study of the first patients treated with PVP by three operators in three different centres (n=152 in group 1, n=112 in group 2, n=101 in group 3) was conducted...

The prevalence of lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) increases with age. While a variety of treatments are available for these men, endoscopic treatments are generally preferred for men with small to moderate size glands. Novel treatment options are continually introduced into this large market. However, the practicing urologist should have a well tested surgical option in regular practice that is applicable to a wide range of patients. Herein we discuss two well recognized surgical options that can be used for the majority of men with LUTS due to BPH who have failed medical management...

PURPOSE: To investigate 5-year long-term postoperative efficacy in benign prostate hyperplasia (BPH) following 120-W GreenLight high-performance system photoselective vaporization of the prostate (HPS-PVP). METHODS: This was a retrospective study of surgical outcomes in 159 men who underwent HPS-PVP and were followed over 60 months postoperatively. Definitions of treatment success were established based on the following three variables: international prostate symptom scores (IPSS), maximum flow rates (Qmax), and quality of life scores QoL)...

PURPOSE: Laser therapy provides an alternative option for treating non-muscle-invasive bladder cancer (NMIBC). However, the clinical evidence for potassium-titanyl-phosphate (KTP) laser en bloc resection is still limited. Here, we investigated the efficacy and safety of the 120-W front-firing KTP laser for the treatment of NMIBC. METHODS: A total of 64 patients with NMIBC treated with either a 120-W front-firing KTP-photoselective vapo-enucleation of the bladder tumor (PVEBT, n=34) or transurethral resection of the bladder tumor (TURBT, n=30) were included...

The surgical treatment of benign prostatic obstruction is changing over the time, thanks the increase evidence about the successful role of laser techniques in this surgery. We aimed to compare prostatic GreenLight photovaporization (PVP) to bipolar transurethral resection of the prostate (TURP) with regard to lower urinary tract symptoms (LUTS) improvement through the evaluation of BPH6. We enrolled 220 consecutive subjects affected by LUTS. We performed a propensity score matching using prostate volume, peak flow and International Prostate Symptoms Score (IPSS)...

Benign prostatic hyperplasia (BPH) is a common pathology causing lower urinary tract symptoms (LUTS) and may significantly impact quality of life. While transurethral resection of the prostate (TURP) remains the gold standard treatment, there are many evolving technologies that are gaining popularity. Photoselective vaporization of the prostate (PVP) is one such therapy which has been shown to be non-inferior to TURP. We aimed to review the literature and discuss factors to optimise patient outcomes in the setting of PVP for BPH...

OBJECTIVE: To evaluate surgical outcomes of patients who underwent complete or incomplete enucleation technique during a short-term postoperative period. MATERIALS AND METHODS: Patients having intractable lower urinary tract symptoms/benign prostatic hyperplasia and prostates >30 g with obstructed pattern in the urodynamic examinations were included. They underwent transurethral resection of prostate (TUR-P), 120 W GreenLight laser high power system-photoselective vapoenucleation of prostate (HPS-PVEP), or holmium laser enucleation of prostate (HoLEP)...

PURPOSE: Postoperative urinary retention is a common complication across surgical specialties. To our knowledge no literature to date has examined postoperative urinary retention as a predictor of long-term receipt of surgery for bladder outlet obstruction. MATERIALS AND METHODS: We retrospectively reviewed the records of inpatients who underwent nonurological surgery in California between 2008 and 2010. Postoperative urinary retention during the index admission was identified, as was receipt of a bladder outlet procedure (transurethral prostate resection, prostate photoselective vaporization or suprapubic prostatectomy) at a subsequent encounter...

PURPOSE: This study evaluated the safety and efficacy of photoselective vaporization of prostate using the 120 W High Performance System for management of symptomatic benign prostatic hyperplasia (BPH). METHODS: We prospectively obtained data from 229 patients between January 2009 and December 2012. We evaluated the serum prostate specific antigen level, International Prostate Symptom Score (IPSS), prostate volume; maximum urine flow rate (Qmax); and postvoid residual urine volume (PVR) in the patients at presentation and on follow-up at 1, 6, 12, and 24 months...

OBJECTIVE: To evaluate the safety and short-term outcomes of photoselective vaporization of the prostate (PVP) using GreenLight XPS™ in treatment of high medical risk (HMR) men. METHODS: A multicenter retrospective analysis of 941 men who underwent PVP between August 2010 and August 2014 was performed. Patients were considered HMR if they had an American Society of Anesthesiologists physical status score ≥3. Postoperative adverse events, unexpected postoperative medical provider visits after intervention, and functional urinary outcomes were examined...

BACKGROUND AND OBJECTIVE: Photoselective vaporization of the prostate (PVP) is an alternative to transurethral resection of the prostate (TURP) in the surgical management of Benign Prostate Obtruction (BPO), with a better hemostatic effect due to a coagulation depth of several millimeters. The objective of this study was to prospectively assess the tissue effects of PVP by Magnetic Resonance Imaging (MRI). MATERIALS AND METHODS: From December to February 2014, ten patients were included in a prospective study and underwent PVP performed by a single surgeon with the Greenlight™ laser 180-W XPS...

BACKGROUND: To assess current treatment trends and perioperative outcomes of transurethral resection of the prostate (TURP) and photoselective vaporization of the prostate (PVP) in a tertiary institution. METHODS: We prospectively collected a database of all patients undergoing TURP and PVP for benign prostatic hyperplasia (BPH) at a tertiary hospital between January 2011 and December 2013. Patient characteristics such as length of stay, readmission, anticoagulation status, American Society of Anesthesiologists (ASA) score and need for blood transfusion were recorded and analysed...
