An electronic device, the electromanometer, was used to obtain a record of peristalsis of the normal human ureter before, during, and after the administration of morphine sulfate, atropine sulfate, propantheline, and atropine tannate in 31 patients. Because of its sensitivity the electromanometer can measure directly the absolute value of pressure in the ureter and the alterations that occur with peristalsis. It is used with a small-caliber catheter in order to avoid obstructive factors that were inherent in prior methods used to evaluate peristalsis of the ureter. The tracings obtained showed that these four drugs in the dosages used did not alter peristalsis of the ureter.
