We investigated whether measurement of contralateral renal length in newborns with unilateral hydronephrosis may help to assess clinically significant hydronephrosis in the affected kidney.
We reviewed our experience with 53 newborns who had unilateral hydronephrosis presumed secondary to ureteropelvic junction obstruction. We divided the patients according to the presence of mild hydronephrosis and no obstruction on a furosemide renogram, severe hydronephrosis and obstruction on a furosemide renogram or a unilateral multicystic kidney.
We found no significant correlation between findings on the affected and opposite normal sides. Contralateral hypertrophy, hypotrophy and normal sized kidneys were frequent findings.
We conclude that measurement of contralateral renal length is not helpful in the evaluation of newborns with unilateral hydronephrosis.
我们研究了测量单侧肾积水新生儿对侧肾脏长度是否有助于评估患侧肾脏临床上显著的肾积水情况。
我们回顾了53例单侧肾积水新生儿的病例，这些患儿推测继发于输尿管肾盂连接部梗阻。我们根据速尿肾图检查结果将患者分为轻度肾积水且无梗阻、重度肾积水且有梗阻或单侧多囊肾。
我们发现患侧和对侧正常侧的检查结果之间无显著相关性。对侧肾脏肥大、萎缩和大小正常是常见的检查结果。
我们得出结论，测量对侧肾脏长度对评估单侧肾积水新生儿并无帮助。
