[The spontaneous activity of the perivesical area of the ureter].

Electrical activity of the ureter pericystic region was found to have a definite own rhythm. Noradrenaline and adrenaline were able to induce rhythmic activity in previously inactive pericystic areas. The existence of pacemaker area in the ureter pericystic region seems to act as an additional system for coordination of polarity of the excitation-contractile waves.
