A clinical pilot study compared predictions of a new model of peritoneal dialysis mass transfer to measured weekly KT/V urea (KTu/V) and weekly creatinine clearance (Ccr) in liters per 1.73 m2 in 50 patients from five centers (40 CAPD, 10 CCPD). The Robertson et al. model is unique in that it does not require a 24-hour collection of dialysate. Instead, model predictions are based on the results of a standard 4-hour peritoneal equilibration test (PET) and appropriate demographic data. Analysis revealed 12 collection errors, 8 affecting the PET and 4 affecting 24-hour dialysate volume. PET drainage volume was low in six cases, excessive in two; 24-hour volume was incomplete in three, excessive in one. Similar errors were not found in the remaining 38 patients. In the 38 patients with correctly performed PET and dialysate collections, agreement between predicted and measured values was excellent.
一项临床试点研究比较了一种新的腹膜透析物质转运模型对来自五个中心的50例患者（40例持续性非卧床腹膜透析患者，10例持续性循环腹膜透析患者）每周尿素清除率（KTu/V）和每1.73平方米体表面积每周肌酐清除率（Ccr，单位为升）的预测值与实测值。罗伯逊等人的模型独特之处在于它不需要收集24小时的透析液。相反，模型预测基于标准4小时腹膜平衡试验（PET）的结果和适当的人口统计学数据。分析发现12例收集错误，其中8例影响PET，4例影响24小时透析液量。PET引流液量在6例中偏低，2例偏高；24小时尿量在3例中不全，1例过多。其余38例患者未发现类似错误。在PET和透析液收集操作正确的38例患者中，预测值与实测值之间的一致性非常好。
