Summary
Photoselective vaporization of the prostate (PVP) with Greenlight laser significantly improves urinary symptoms and voiding parameters. While generally safe, long-term data on functional outcomes and complications beyond three years are limited.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Laser Technology
Background:
- Benign prostatic hyperplasia (BPH) affects millions of men globally, necessitating effective treatment options.
- Photoselective vaporization of the prostate (PVP) using Greenlight laser has emerged as a popular minimally invasive BPH treatment.
- Assessing the comprehensive outcomes and complication profile of PVP is crucial for clinical decision-making.
Purpose of the Study:
- To systematically review the outcomes of photoselective vaporization of the prostate (PVP) using Greenlight laser.
- To evaluate the intraoperative, perioperative, and long-term complications associated with PVP.
- To synthesize current evidence on the efficacy and safety of different Greenlight laser generations (80W, 120W, 180W).
Main Methods:
- Systematic review adhering to PRISMA guidelines.
- Inclusion of studies published between 2009 and 2014.
- Analysis of outcomes including micturition symptoms (IPSS, QoL) and voiding parameters (Qmax, PVR volume).
Main Results:
- All Greenlight laser generations demonstrated significant improvements in micturition symptoms and voiding parameters.
- Intraoperative complication rates were low.
- Data on sexual function showed heterogeneity, with a trend toward decreased erectile function in some patients. Perioperative and postoperative complication rates varied, influenced by documentation heterogeneity.
Conclusions:
- PVP offers statistically significant and clinically relevant improvements in voiding parameters and symptoms for prostates <100 ml.
- The procedure is characterized by high intraoperative and perioperative safety.
- Further long-term randomized controlled trial (RCT) data beyond 3 years are needed for all Greenlight laser generations to fully understand functional outcomes and complications.

Vaporization
33.2K
The physical form of a substance changes by changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. For vaporization to occur, kinetic energy must be greater than the intermolecular forces that keep molecules bonded. The amount of energy needed to vaporize a quantity of liquid at a given pressure and a constant temperature is called the heat of vaporization. When...

Photoluminescence: Applications
1.2K
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

Vapor Pressure Lowering
25.0K
The equilibrium vapor pressure of a liquid is the pressure exerted by its gaseous phase when vaporization and condensation are occurring at equal rates: Dissolving a nonvolatile substance in volatile liquid results in a lowering of the liquid’s vapor pressure. This phenomenon can be explained by considering the effect of added solute molecules on the liquid's vaporization and condensation processes. To vaporize, solvent molecules must be present at the surface of the solution. The...
