对四条临床通畅的输尿管进行双J支架原位上尿路压力流量研究表明，尿流主要发生在支架周围，并且存在显着的膀胱肾压力传递。本研究探讨了输尿管尿流的动力学和形态学的影响，随之而来的stenting一个ureterin vivo.In猪模型，输尿管插管引起肾盂内压力上升，hydureter，膀胱肾反流和普遍增厚的输尿管壁的尿路特征性组织学变化。这些发现表明，双J支架可能会影响尿液引流时，输尿管梗阻不存在，敦促谨慎使用在受损，通畅的上尿路。
Upper tract pressure flow studies in four clinically unobstructed ureters with double J stentsin situindicated that urinary flow occurred mainly around the stent and that there was significant vesicorenal pressure transmission. This study examined the dynamics of ureteric urinary flow and morphological effects consequent upon stenting a ureterin vivo.In a porcine model, ureteric intubation caused a rise in intrapelvic pressures, hydroureter, vesicorenal reflux and generalised thickening of the ureteric wall with characteristic histological changes in the urothelium. These findings suggest that double J stents may compromise urinary drainage when ureteric obstruction is not present, urging caution in their use in the damaged, unobstructed upper urinary tract.
