通过检测输尿管压力、输尿管管径和长度改变、输尿管测压描图及肌电活动的改变,明确了输尿管梗阻后的功能反应可分为五个阶段,即代偿性功能亢进期、功能不全期、失代偿期、应力性松弛期及扩张期。与不利尿组相比,给予利尿后输尿管的蠕动功能提早失代偿,腔内静息压更低,扩张更明显,解除梗阻后蠕动功能恢复更慢。事实上梗阻侧并无利尿,解除梗阻后尿流率也低于非利尿组。于部分梗阻的动物 Through the detection of ureteral pressure, ureteral diameter and length changes, ureterography and electromyography changes in myoelectric activity, clear the functional response after ureteral obstruction can be divided into five stages, compensatory hyperthyroidism, dysfunction, Decompensated, stress relaxation and expansion period. Compared with non-diuretic group, the ureteral peristalsis function was decompensated prematurely after diuresis, and the intra-venous resting pressure was lower and the dilatation was more obvious. The peristaltic function recovered more slowly after the obstruction was relieved. In fact, there was no diuretic on the obstruction side, and the urinary flow rate was also lower after the obstruction was removed than in the non-diuretic group. Partially obstructed animals
