The paper presents the experimental work carried out on the influence of various surgical situations on ureteral peristalsis in the rat. It included 43 rats divided in three groups. Group I (n = 10) acted as control group and had only ureterolysis performed. In group II (n = 10), single section and subsequent anastomosis was performed. Group III (n = 23) included section at two levels, ureter extraction from the animal and subsequent autotransplantation of the ureter. The three groups were re-operated two months later to ratify peristalsis of the intervened ureter. Both in the first and second operations peristalsis, as well as the features and appearance of antiperistaltic waves were quantified. After 60 days, no changes were observed in group I, but groups II and III exhibited normal peristalsis to presence of antiperistaltic waves. Both groups had complications like stenosis, fistulas and hydronephrosis, but also normal functioning, histology and peristalsis.
本文介绍了关于各种手术情况对大鼠输尿管蠕动影响的实验研究。该研究纳入了43只大鼠，分为三组。第一组（n = 10）作为对照组，仅进行输尿管松解术。第二组（n = 10）进行单次切断并随后吻合。第三组（n = 23）包括在两个层面切断、从动物体内取出输尿管并随后进行输尿管自体移植。两个月后对三组大鼠再次手术，以确认干预后输尿管的蠕动情况。在第一次和第二次手术中，均对蠕动以及逆蠕动波的特征和表现进行了量化。60天后，第一组未观察到变化，但第二组和第三组出现了正常蠕动及逆蠕动波。两组均出现了诸如狭窄、瘘管和肾积水等并发症，但也有正常的功能、组织学表现和蠕动。
