In newborn babies with congenital renal pathology type agenesia, dysplasia or obstruction is very important to know if there is intrautero vicariant growing of the contralateral kidney. To find out that we have proceeded to be ultrasound volume measurement of the normal renal unit, as this is a valuable parameter related to compensatory mechanisms. We have studied by ultrasounds 28 renal units (16 right, 12 left) in newborns with contralateral pathology: pyeloureteral stenosis in 10 cases, multicystic kidney in 13 cases, renal agenesia in 3 cases, obstructive ureterocele in 1 case and another one with ureterovesical stenosis. We considered renal function, length of the larger renal axis width and depth of the kidney mass. Renal function was normal in all cases. Analysis of objectives results show a clear difference between the volume of normal Kidneys in children with contralateral pathology and the control group constituted by 42 renal unit in normal newborns without urological pathology. We conclude with the real evidence of compensatory growing of the normal contralateral kidney during intrautero periods.
对于患有先天性肾脏病理类型发育不全、发育异常或梗阻的新生儿，了解对侧肾脏在子宫内是否存在替代性生长非常重要。为了弄清楚这一点，我们对正常肾单位进行了超声容积测量，因为这是一个与代偿机制相关的重要参数。我们对28个肾单位（16个右侧，12个左侧）进行了超声检查，这些新生儿患有对侧病理情况：肾盂输尿管狭窄10例，多囊肾13例，肾发育不全3例，梗阻性输尿管囊肿1例，另1例为输尿管膀胱狭窄。我们考虑了肾功能、肾脏最大轴长、宽度和肾实质深度。所有病例肾功能均正常。目标结果分析显示，患有对侧病理情况的儿童正常肾脏体积与由42个无泌尿系统病理的正常新生儿肾单位组成的对照组之间存在明显差异。我们得出结论，有实际证据表明在子宫内时期正常对侧肾脏存在代偿性生长。
