By means of a newly developed measuring catheter the occluding force of the ureter under changing diuresis conditions was investigated using 12 canine ureters. Even under extremely high flow rates of some 50 times normal values, the ureter returned after short phases of noncoaptive transport to active bolus transport. No direct connection between flow rate and basal pressure on the one hand and the form of transport on the other hand was observable. Only after prolonged continuous loading on the ureter with high flow rates was a loss of occluding forces observed with the noncoaptive form of transport, then taking on more significance.
通过一种新开发的测量导管，使用12条犬输尿管研究了在不同利尿条件下输尿管的闭塞力。即使在约为正常值50倍的极高流速下，输尿管在经历短暂的非适应性输送阶段后仍会恢复为主动团块输送。未观察到流速和基础压力一方面与输送形式另一方面之间存在直接关联。仅在输尿管长时间持续承受高流速负荷后，才观察到非适应性输送形式下闭塞力的丧失，此时这种情况变得更加显著。
