[Intramural blood flow and neurogenic regulation changes of the bladder wall of rats with infravesical obstruction based on harmonic analysis of bioimpedans].

During high pressure in the bladder, particularly during delay of urination because of infravesical obstruction, raisings of blood pressure were marked with simultaneous increase of renal and spleen sympathetic nerves activity. During urination the activity of sympathetic nervous system decreases while the activity of parasympathetic system which is responsible for detrusor contraction increase. All these data testify to changes of vegetative regulation of hypertrophic bladder during inftavesical obstruction, but on the other hand mechanism of those changes and their functional consequences require further studies.
