4 +/- 3 9 to 18 4 +/- 8 4 ml per second Urethral stricture rates

4 +/- 3.9 to 18.4 +/- 8.4 ml per second. Urethral stricture rates were 1.7% vs 5.7%, bladder neck contractures were 3.5% vs 7.7% and revaporization rates were 3.5% vs 1.9% in the holmium laser ablation and photoselective vaporization groups, respectively.

Conclusions: Holmium laser ablation and photoselective vaporization of the prostate are safe and effective in patients with benign prostatic hyperplasia with a small to moderate size prostate. Both procedures are easy to learn but holmium laser ablation of the prostate requires a longer operating time.”
“The role of endogenous nitric

oxide (NO) in modulating myocardial contractility is still unclear, in part because of unknown, secondary effects of blocking NO release. We hypothesized that the nonspecific inhibition of nitric oxide synthase (NOS) enhances endothelin-1 (ET-1) effects, which this website can play a role in ET-A receptor-dependent myocardial contractile responses. The myocardial contractility was estimated from the slope of the left ventricular end-systolic pressure-diameter relationship in closed-chest, pentobarbital-anesthetized dogs. Group 1 (n = 7) was the saline-treated control, while in groups 2 (n = 7) and 3 (n = 7) N-nitro-L-arginine (NNA, 4 mg kg(-1)), a nonselective NOS blocker, was administered with or without pretreatment

with the ET-A receptor antagonist ETR-P1/fl peptide (100 nmol kg(-1) iv). Plasma ET-1, nitrite/nitrate (NO(x)) and blood superoxide levels were measured, and myocardial LY3023414 concentration IKBKE ET-1 content and xanthine oxidoreductase (XOR) activity were determined from myocardial biopsies. The infusion of NNA over 120 min decreased the plasma NO(x), significantly elevated the plasma ET-1 and blood superoxide levels, and in parallel greatly increased the left ventricular contractility as compared with the untreated controls [47.5 vs 30 mm Hg mm(-1)]. The myocardial ET-1 content decreased simultaneously, while the XOR activity and blood superoxide level were significantly elevated. These effects, including NNA-induced

positive inotropy, were significantly suppressed by pretreatment with ETR-P1/fl peptide. These results demonstrate that a diminished NO synthesis leads to a preponderant ET-1 effect, which increases myocardial contractility through an ET-A receptor-dependent mechanism.

“Purpose: Length and location of positive surgical margins are independent predictors of biochemical recurrence after open radical prostatectomy. We assessed their impact on biochemical recurrence in a large robotic prostatectomy series.

Materials and Methods: Data were collected prospectively from 1,398 men undergoing robotic radical prostatectomy for clinically localized prostate cancer from 2003 to 2008 at a single institution.
