Search for: [Abstract = "f adrenaline, noradrenaline were measured by immunochemistry in both groups. Additionally,a serum sample was obtained for Prostate Specific Antigen and its derivatives analysis.ANS activity was assessed by HRV measurements in resting conditions,after simulation with deep breating and by tilt test.In the HRV recording,frequency domain analysis parameters were calculated according to fast Fourier transformation and the correlation for ANS activity parameters vs.BPH variables were analysed.The heart variability assessment generally demonstrates the over\-stimulation of the sympathetic component of ANS at rest in patients with BPH and secondary LUTS,when compared to control group.These sympathetic overdrive correlated when compared to control group.These sympathetic overdrive correlated with high noradrenaline leves et rest in patients.Autonomic tests confirmed ANS dysfunction in this group of patients.In deep breating and in the tilt up tests,impaired parasympathetic response of ANS to stimulation was observed. Understanding the Ans profile in BPH pathophysiology could be a nesessery condition for the proper selection of patients with LUTS,who can benefit from pharmacological modulation of sympathetic or parasympathetic components of ANS activitv."]
