恒压肾盂灌注试验在判断上尿路手术疗效中的作用

Constant pressure perfusion of the renal pelvis in the assessment of the outcome of surgical reconstruction for upper urinary tract obstruction

用恒压肾盂灌注（ＣＰＰ）试验检测了１０例解除上尿路梗阻术后病人上尿路功能，并将其结果与夹管试验和造影检查比较，以评价手术疗效。ＣＰＰ试验结果通畅者术后随访肾功能均改善，不通畅者则肾功能恶化。夹管试验阴性者大部分肾功能改善，小部分肾功能恶化。造影检查通畅者肾功能均改善，但有部分梗阻者，其预后难以估计。我们认为ＣＰＰ试验判断上尿路梗阻解除手术疗效准确可靠。

To assess the efficacy of surgical management for upper urinary tract obstruction,constant pressure perfusion(CPP)test was carried out postoperatively in 10patients.The results were compared with urographic findings and clinical tube-clamp testing.The functional status of the kidney detected on follow up study corresponded well with the results observed on CPP test.When the reconstructed site was considered patent on tube-clamp testing.the kidney function improved in most cases but being progressively deteriorated in a few.When the reconstructed site was patent on urographic studies,the kidney function always improved but when partial obstruction was observed,the prognosis would be uncertain.CPP test was considered accurate and reliable in the assessment of the outcome of surgical reconstruction for upper urinary tract obstruction.
