Exigencies of societal demands for alternatives to the not inconsiderable morbidity and significant and increasing cost of transurethral resection of the prostate (TURP) paved the way for development of a multitude of therapies for obstructive benign prostatic hyperplasia (BPH). Among them, laser prostatectomy (LP) attracted much attention. However, phenomenal appeal of earlier coagulative and later cutting (enucleative) or even some vaporizing LP techniques has vanished or waned largely due to… Expand
Initial romanian experience with green light hps 120 w laser in bph
Introduction and objectives:Potassium-titanyl-phosphate (KTP) laser photoselective vaporization prostatectomy (PVP) is a relatively new technology for the management of benign prostatic hyperplasiaExpand
Photoselective potassium-titanyl-phosphate (KTP) laser vaporization of the prostate (PVP) vs transurethral resection of the prostate (TURP).
TLDR
The opinion of multiple investigators that the role of statins in preventing cancer is promising and warrants basic science research and large randomized clinical trials with longer follow-up is shared. Expand
KTP green laser vaporization of biologic tissue under water and its clinical application.
TLDR
With increasing laser power settings, the vaporization depth and width increased significantly, but the depth of necrosis declined slightly, suggesting green laser vaporization is a treatment method that can be adopted to treat patients with BPH, urethral stricture, and other urological diseases safely and effectively.

Greenlight photoselective 120-watt 532-nm lithium triborate laser vaporization prostatectomy in living canines.
TLDR
The authors' in vivo canine survival study demonstrates GreenLight HPS 120-W, 532-nm LBO laser PVP has substantially more vaporization efficiency and speed, with equally favorable tissue interaction and healing vis-à-vis those benchmarked for the 5 32-nm wavelength by KTP Laser PVP. Expand
Photoselective vaporization prostatectomy: experience with a novel 180 W 532 nm lithium triborate laser and fiber delivery system in living dogs.
TLDR
GreenLight XPS 180 W 532 nm lithium triborate laser photoselective vaporization of the prostate with the MoXy fiber has a significantly higher vaporization rate and speed with a deeper hemostatic coagulation zone but favorable tissue interaction and healing equal to those of HPS 120 W laser photOSElective vapors in dogs. Expand
Potassium titanyl phosphate laser tissue ablation: development and experimental validation of a new numerical model.
TLDR
A two dimensional computational model based on the control volume finite difference and the enthalpy method that was able to capture the general trends experimentally observed in terms of ablation and coagulation areas and the ablation rate is a useful first step in the mechanistic prediction of PVP based BPH laser tissue ablation. Expand
Urethral injury during potassium-titanyl-phosphate laser prostatectomy complicated by transurethral resection syndrome.
TLDR
This is the first report of a patient undergoing photoselective vaporization of the prostate who developed full-blown transurethral resection syndrome because of intravascular absorption of sterile water. Expand

Laser prostatectomy (LP) was developed to reduce the complications and cost associated with transurethral resection of the prostate (TURP) for the treatment of obstructive benign prostaticExpand
Interaction between high power 532nm laser and prostatic tissue: in vivo evaluation for laser prostatectomy
TLDR
This canine study demonstrates that 180W 532-nm laser PVP with its new fiber has a significantly higher ablation rate with a more hemostatic coagulation zone, but equally favorable tissue interaction and healing, compared with the previous 120W canine study. Expand
Laser vaporization of bovine prostate: a quantitative comparison of potassium-titanyl-phosphate and lithium triborate lasers.
TLDR
In vitro the lithium triborate GreenLight HPS 120 W laser vaporizes bovine prostate far more efficiently than the KTP photoselective vaporization laser but coagulates it equally well. Expand

TLDR
Long-term experience and the literature suggest that significant improvements in symptomatic and urodynamic outcomes of photo-selective vaporization of the prostate are achievable and sustainable. Expand
High power potassium-titanyl-phosphate laser vaporization prostatectomy.
TLDR
The authors' observation in a 2-year period indicates that KTP laser vaporization prostatectomy is safe and effective for quickly relieving bladder outlet obstruction with minimal postoperative complications, a high rate of patient satisfaction and, to date, a generally good outcome. Expand
Laser prostatectomy: our initial experience of a technique in evolution.
TLDR
Laser prostatectomy is an exciting field with considerable potential but remains in the developmental stage, and encouraging early results have been achieved using forward-firing fibers to treat apical and middle lobe tissue. Expand
High-power potassium-titanyl-phosphate (KTP/532) laser vaporization prostatectomy: 24 hours later.
TLDR
The very early and limited experience indicates that high-power KTP/532 laser vaporization prostatectomy is feasible and appears to be safe and effective for quickly relieving bladder outlet obstruction due to BPH. Expand
Potassium-titanyl-phosphate laser vaporization of the prostate: a comparative functional and pathologic study in canines.
TLDR
KTP laser vaporization prostatectomy not only provides hemostasis similar to that obtained with Nd:YAG laser coagulation, but also removes tissue at the time of operation, allowing dogs to void without straining within 24 hours of treatment. Expand

TLDR
PVP is a unique, safe and effective outpatient modality that provides immediate symptomatic and urodynamic relief of bladder outlet obstruction secondary to BPH and long-term followup is needed to validate further the maintenance of clinical efficacy beyond 1 year. Expand
Randomized comparison of transurethral electroresection and holmium: YAG laser vaporization for symptomatic benign prostatic hyperplasia.
TLDR
Although taking slightly longer to accomplish, holmium:YAG laser vaporization of BPH provides early results very similar to those of TURP with a shorter catheterization time and no initial dysuria or pain. Expand
Laser prostatectomy: two and a half years' experience with aggressive multifocal therapy.

Aggressive Nd:YAG laser prostatectomy is safe and effective for obstructive prostates up to 70 mL in volume and produces good results that are sustained for up to 2 1/2 years. Expand
