Interrelation between neural control of urinary bladder and prostate during different phases of bladder activity
In narcotized dogs, electrical impedances of prostate and urinary bladder were recorded simultaneously with vesical pressure to assess neural control and circulation in these organs in vivo with the method of bioimpedance harmonic analysis. Regional sympathetic and parasympathetic activities were assessed by the magnitude of Mayer (M) and respiratory (R) peaks, correspondingly. Circulation in these organs was evaluated according to the magnitude of the first pulsatile (cardiac) harmonic C1.
