The effects of ureteric torsion on the upper urinary tract were studied in 8 pigs. With 5 pigs the distal ureter was mobilised, torted 1 to 5 times and reimplanted into the bladder. With three pigs the proximal ureter was torted 1 to 3 times and re-anastomosed to the renal pelvis. It was shown that a torsion of 1 or 2 times in the distal ureter does not result in ureteral obstruction. However, as little as 360 degrees torsion in the proximal ureter may lead to dysfunction secondary to mechanical obstruction. Histological examination of the ureter showed ischaemic changes only after multiple torsions.
在8头猪身上研究了输尿管扭转对上尿路的影响。对5头猪，游离远端输尿管，扭转1至5次后再植入膀胱。对3头猪，近端输尿管扭转1至3次后再与肾盂吻合。结果显示，远端输尿管扭转1或2次不会导致输尿管梗阻。然而，近端输尿管扭转低至360度可能会导致继发于机械性梗阻的功能障碍。输尿管的组织学检查显示，仅在多次扭转后才出现缺血性改变。
