The excretory urographies of 26 patients with unilateral pelviureteric obstruction were analysed retrospectively. All patients had had dismembered pyeloplasty performed at the age of 9 months to 15 years 2 months. Planimetric parenchymal area measurements of each kidney were made from urographies performed preoperatively and at different stages of the follow-up period, the latest follow-ups being effected 3 to 14 years postoperatively. The postoperative parenchymal growth of the hydronephrotic kidneys was very good, especially in patients operated on in early childhood. The mean parenchymal growth rate in per cent of the hydronephrotic kidney exceeded the mean parenchymal growth rate in per cent, of its mate during the first postoperative year. During the long-term follow-up there was no further parenchymal "catch-up" growth of the hydronephrotic kidney as compared to the contralateral kidney. Planimetric measurement of kidney parenchymal area is proposed as a useful quantitative method for the preoperative and postoperative evaluation of hydronephrosis in children.
对26例单侧肾盂输尿管梗阻患者的排泄性尿路造影进行回顾性分析。所有患者均在9个月至15岁2个月时接受了肾盂成形术。通过术前及随访不同阶段的尿路造影测量每个肾脏的平面实质面积，最近一次随访在术后3至14年进行。肾积水肾脏术后的实质生长情况非常好，尤其是在幼儿期接受手术的患者中。术后第一年，肾积水肾脏实质生长率的平均值超过其对侧肾脏实质生长率平均值的百分比。在长期随访中，与对侧肾脏相比，肾积水肾脏没有进一步的实质“追赶”生长。建议采用肾脏实质面积的平面测量法作为术前和术后评估儿童肾积水的一种有用的定量方法。
