For the sake of clarity it is proposed to label the methods of transureteral ureterostomy as TUUS I and TUUS II. The "volume-impulse method" is used to obtain information on the flow situation from the non-fistulated kidney in TUUS II. It must be considered that all results were obtained under the most favourable conditions of the supine splint. Moreover the flow situation varies according to individual conditions. Following an initial increase in pressure in the non-fistulated system with infinitely great flow resistance of the ureter, an "opening pressure" ist achieved, at which the flow resistance has reached a finite level and drainage from the renal pelvis begins. Above this pressure the flow resistance is regulated so that the increase in pressure caused by normal diuresis is almost negligible. A flow equilibrium is attained in the non-fistulated kidney at pressures which, although unphysiologically high, allow the kidney to function.
为清晰起见，建议将经输尿管输尿管造口术的方法标记为TUUS I和TUUS II。在TUUS II中，“容积-脉冲法”用于获取来自未造瘘肾脏的血流情况信息。必须考虑到，所有结果都是在仰卧位夹板的最有利条件下获得的。此外，血流情况会因个体情况而异。在输尿管具有无限大血流阻力的未造瘘系统中，压力最初升高后，会达到一个“开放压力”，此时血流阻力达到一个有限水平，肾盂开始引流。高于此压力时，血流阻力会受到调节，以使正常利尿引起的压力升高几乎可以忽略不计。在未造瘘肾脏中，在虽高于生理水平但能使肾脏发挥功能的压力下达到血流平衡。
