ABSTRACT:
A method is provided of removing urinary concretions from the ureter of patients whose anatomical peculiarties do not permit application of disintegrating instruments. The method involves an ultrasonic vibratory action upon the ureteral wall below the region where the concretion is lodged to stimulate peristaltic contractions of the urinary tract and free passage of the concretion. The local vibratory action upon the ureter involves no unfavorable effects upon the internal organs, cardiovascular or nervous systems of the patient.
