The diagnosis of multicystic renal dysplasia is confirmed by a combination of sonography and radionuclide scan. If the contralateral kidney is normal by these criteria, further radiological examination is often omitted. We prospectively studied 29 patients with a diagnosis of multicystic renal dysplasia by voiding cystourethrography to determine the condition of the solitary contralateral kidney. Eight patients (28%) were found to have contralateral vesicoureteral reflux, of whom 6 had normal ultrasound examinations and would not have undergone further radiographic study based on ultrasound criteria alone. Contralateral vesicoureteral reflux in association with multicystic renal dysplasia puts solitary kidneys at risk for pyelonephritic scarring. Therefore, voiding cystourethrography should be performed as part of the initial evaluation of all infants with multicystic renal dysplasia.
多囊性肾发育不良的诊断通过超声检查和放射性核素扫描相结合来确定。如果按照这些标准对侧肾脏正常，通常可省略进一步的放射学检查。我们前瞻性地研究了29例经排尿性膀胱尿道造影诊断为多囊性肾发育不良的患者，以确定对侧孤立肾的情况。发现8例患者（28%）存在对侧膀胱输尿管反流，其中6例超声检查正常，仅根据超声标准不会接受进一步的影像学检查。与多囊性肾发育不良相关的对侧膀胱输尿管反流使孤立肾有发生肾盂肾炎瘢痕形成的风险。因此，排尿性膀胱尿道造影应作为所有多囊性肾发育不良婴儿初始评估的一部分进行。
