The postoperative increase of the renal parenchyma, measured with planimetry on repeated urography films, was studied in 24 infants and children. All patients had been operated on because of unilateral stenosis of the pelvioureteral junction. When the results were analyzed in a pair-control manner the paired members were almost identical for age at operation, affected side, sex, presenting clinical sign and length of followup. The 12 patients who underwent a dismembered pyeloplasty displayed a significantly stronger mean catch-up growth of the relative parenchymal area than the 12 patients who underwent a nondismembered technique. Speculatively, this difference may reflect in part the protection of the growing renal parenchyma by the preoperatively compliant and wide renal pelvis, which had led to resection and dismembered correction.
我们对24例婴幼儿和儿童进行了研究，通过在重复尿路造影片上用面积测量法测量术后肾实质的增加情况。所有患者均因肾盂输尿管连接处单侧狭窄而接受手术。当以配对对照方式分析结果时，配对成员在手术年龄、患侧、性别、临床表现和随访时间方面几乎相同。与12例采用非离断性技术的患者相比，12例行离断性肾盂成形术的患者相对实质面积的平均追赶生长明显更强。据推测，这种差异可能部分反映了术前顺应性好且宽大的肾盂对生长中的肾实质的保护作用，这导致了切除和离断性矫正。
