The electromyogram and bolus volume of ureteral peristalsis were measured during gradual and rapid urinary flow increase, using 16 mongrel dogs. When the urine flow was increased rapidly by administration of diuretics, the ureteral peristaltic rate always increased first, then the urine bolus volume increased and finally the ureter became a urinary column without forming the urine bolus. When the urine flow was increased gradually by intravenous drip infusion of saline solution, the ureteral peristaltic rate and urine bolus volume did not always increase in spite of urinary flow increase. The peristaltic rate and bolus volume helped each other for effective urinary transport, as both of them not only always increase but also one of them occasionally decreased.
使用16只杂种犬，在逐渐增加和快速增加尿流期间测量输尿管蠕动的肌电图和尿团体积。当通过给予利尿剂使尿流快速增加时，输尿管蠕动频率总是先增加，然后尿团体积增加，最后输尿管变成无尿团形成的尿柱。当通过静脉滴注生理盐水使尿流逐渐增加时，尽管尿流增加，输尿管蠕动频率和尿团体积并不总是增加。蠕动频率和尿团体积相互协同以实现有效的尿液输送，因为它们不仅总是增加，而且其中之一偶尔会减少。
