PURPOSE: To evaluate perioperative cost related to surgical treatments of benign prostatic obstruction (BPO): photoselective vaporization of the prostate (pvp), holmium/thullium laser enucleation (HoLEP/ThuLEP), transurethral resection of the prostate (TURP) and open prostatectomy (OP). MATERIAL AND METHODS: We retrospectively collected data from 237 patients who consecutively underwent a surgical treatment for BPH between January 2012 and June 2013 at nine institutions in France...

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...

BACKGROUND: Photoselective vaporization of the prostate is a technique that is widely used for the treatment of benign prostatic hyperplasia (BPH) and has pronounced advantages compared to the traditional transurethral resection of the prostate. Following the recent introduction of end-firing lithium triborate lasers, we have created a new technique called photoselective vaporesection of the prostate (PVRP). This study described our initial experience using the PVRP technique for the treatment of BPH...

The purpose of this study is to assess the safety and efficacy of GreenLight laser photoselective vaporization of the prostate (PVP) for the treatment of benign prostate hyperplasia/lower urinary tract symptoms (BPH/LUTS) in patients with different post-void residual urine (PVR). BPH/LUTS patients treated with PVP from January 2014 to January 2016 were enrolled in the present study. All patients were divided into PVR > 50, 50 ≤ PVR < 400, and PVR ≥ 400 ml groups, and standard general and urological methods for BPH/LUTS were carried out...

Five heteroleptic tris-diimine ruthenium(II) complexes [RuL(N^N)2](PF6)2 (where L is 3,8-di(benzothiazolylfluorenyl)-1,10-phenanthroline and N^N is 2,2'-bipyridine (bpy) (1), 1,10-phenanthroline (phen) (2), 1,4,8,9-tetraazatriphenylene (tatp) (3), dipyrido[3,2-a:2',3'-c]phenazine (dppz) (4), or benzo[i]dipyrido[3,2-a:2',3'-c]phenazine (dppn) (5), respectively) were synthesized. The influence of π-conjugation of the ancillary ligands (N^N) on the photophysical properties of the complexes was investigated by spectroscopic methods and simulated by density functional theory (DFT) and time-dependent DFT...

Ultrafast photochemistry of pharaonis halorhodopsin (p-HR) in the intact membrane of Natronomonas pharaonis has been studied by photoselective femtosecond pump-hyperspectral probe spectroscopy with high time resolution. Two variants of this sample were studied, one with wild-type retinal prosthetic groups and another after shifting the retinal absorption deep into the blue range by reducing the Schiff base linkage, and the results were compared to a previous study on detergent-solubilized p-HR. This comparison shows that retinal photoisomerization dynamics is identical in the membrane and in the solubilized sample...

Photoelectron circular dichroism refers to the forward/backward asymmetry in the photoelectron angular distribution with respect to the propagation axis of circularly polarized light. It has recently been demonstrated in femtosecond multi-photon photoionization experiments with randomly oriented camphor and fenchone molecules [C. Lux et al., Angew. Chem., Int. Ed. 51, 4755 (2012) and C. S. Lehmann et al., J. Chem. Phys. 139, 234307 (2013)]. A theoretical framework describing this process as (2+1) resonantly enhanced multi-photon ionization is constructed, which consists of two-photon photoselection from randomly oriented molecules and successive one-photon ionization of the photoselected molecules...

In oxygenic photosynthesis, two photosystems work in series. Each of them contains a reaction centre that is surrounded by light-harvesting antennae, which absorb the light and transfer the excitation energy to the reaction centre where electron transfer reactions are driven. Here we report a critical test for two contrasting models of light harvesting by photosystem II cores, known as the trap-limited and the transfer-to-the trap-limited model. Oriented single crystals of photosystem II core complexes of Synechococcus elongatus are excited by polarized visible light and the transient absorption is probed with polarized light in the infrared...

PURPOSE: To evaluate the long-term outcomes and safety photoselective vaporization of the prostate (PVP). PATIENTS AND METHODS: From April 2005 to December 2015, a total of 1154 patients with benign prostatic hyperplasia underwent PVP. The type of Green Light laser was an 80 W potassium-titanyl-phosphate laser and later a 120 W lithium triborate laser. Before and after surgery, the International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), post-voiding volume of residual urine (PVR), prostate-specific antigen (PSA) level, and prostate volume were assessed regularly...

BACKGROUND AND OBJECTIVES: Our objective was to describe the progressive introduction of photoselective vaporization of the prostate (PVP) in an academic department of urology in an outpatient care setting and report our outcomes after the first 100 cases. PATIENTS AND METHODS: Since May 2014, XPS GreenLight™ (Boston Scientific-AMS, USA) PVP in the treatment of benign prostatic hyperplasia was introduced in our department. A prospective local registry was opened to collect patients' demographics, preoperative characteristics and surgical outcomes including operative time, length of stay, catheterization time, and postoperative complications as well as functional outcomes...

Bladder neck contracture (BNC) after GreenLight laser photoselective vaporization (PVP) of benign prostatic hyperplasia is a common complication. In the present study, data of patients received 80 or 180 W PVP were collected. Perioperative parameters, including applied energy, irradiation time, catheter removal time, and hospital stay, were recorded. Postoperative parameters, including maximum urinary flow rate, International Prostate Symptom Score, post-void residual volume, and incidences of BNC, were recorded at 3 and 12 months after operations...
