OBJECTIVE
To explore the effects of ureteral stent placement on ureteral peristalsis and the time course of renal pelvic pressure changes.
METHOD
Forty rabbits were randomized equally into 8 groups, including a control group without placement of ureteral stents. The other 7 groups received ureteral stent placement, which were retained for 0, 1, 2, 3, 4, 7, and 12 weeks respectively. When the rabbits were bred for the specified time periods, ureteral peristalsis was observed and renal pelvic pressure measured.
RESULT
The renal pelvic pressure was initially increased after the stent placement, but then followed by gradual decreases. Ureteral peristalsis was not observed after the stent placement.
CONCLUSION
Ureteral stent is a factor for causing obstruction in normal ureter.
目的
探讨输尿管支架置入对输尿管蠕动及肾盂压力变化时间进程的影响。
方法
40只兔被随机均分为8组，包括未置入输尿管支架的对照组。其他7组接受输尿管支架置入，分别留置0、1、2、3、4、7和12周。当兔饲养至规定时间段时，观察输尿管蠕动并测量肾盂压力。
结果
支架置入后肾盂压力最初升高，但随后逐渐下降。支架置入后未观察到输尿管蠕动。
结论
输尿管支架是导致正常输尿管梗阻的一个因素。
