OBJECTIVE
An experimental study was conducted in rats to assess urographically the function of the integrated autologous free graft (IAFG) of the ureter, in which the ureter is reimplanted after being extracted from the animal's body and involves complete devascularization and ureteral ischemia.
METHODS
The technique employed included direct vascular injection of contrast (iliac vein). The 40 rats were randomly distributed into three groups: NU group (n = 20), normal ureter; SC group (n = 15), surgical control, only ureterolysis; RU group (n = 14), reimplanted ureter as IAFG.
RESULTS
The results show the urographic characteristics of the normal ureter (NU). The SC group IVUS were not distinct from those of the NU group. In the RU group, the segment of the ureter used as IAFG showed a normal or abnormal urographic image, depending on the result of the anastomosis. No ureteral fistula or leakage was observed in the urograms.
目的
在大鼠身上进行一项实验研究，以通过尿路造影评估输尿管自体游离移植术（IAFG）的功能，该手术是将输尿管从动物体内取出后重新植入，涉及完全去血管化和输尿管缺血。
方法
采用的技术包括通过髂静脉直接血管内注射造影剂。40只大鼠随机分为三组：NU组（n = 20），正常输尿管组；SC组（n = 15），手术对照组，仅行输尿管松解术；RU组（n = 14），作为IAFG的再植输尿管组。
结果
结果显示了正常输尿管（NU）的尿路造影特征。SC组的IVUS与NU组无明显差异。在RU组中，用作IAFG的输尿管段根据吻合结果显示出正常或异常的尿路造影图像。尿路造影中未观察到输尿管瘘或渗漏。
