Late results after a secondary pyeloplasty because of failure of the initial procedure were evaluated by glomerular filtration rate and drainage function studies in 15 patients. Total and separate glomerular filtration rates were measured using the 51chromium-ethylenediaminetetraacetic acid clearance technique and isotope renography. The drainage function of the renal pelvis was evaluated from the isotope renogram. Secondary pyeloplasty was performed 1 to 15 years (mean 8.0 years) after the first procedure because of obstruction, which was verified by diuretic urography and isotope renography. Our results show that a secondary pyeloplasty can be performed after failure of the primary procedure. Functional results 3 to 15 years after reoperation were equally good as after uncomplicated primary pyeloplasty.
对15例因初次手术失败而接受二次肾盂成形术的患者，通过肾小球滤过率和引流功能研究评估其远期结果。采用51铬-乙二胺四乙酸清除技术和同位素肾造影测量总肾小球滤过率和分侧肾小球滤过率。从同位素肾图评估肾盂的引流功能。由于利尿性尿路造影和同位素肾造影证实存在梗阻，二次肾盂成形术在初次手术后1至15年（平均8.0年）进行。我们的结果表明，初次手术失败后可进行二次肾盂成形术。再次手术后3至15年的功能结果与单纯初次肾盂成形术后一样良好。
