返流性肾病(Reflux Nepbropathy简称RN)是慢性肾盂肾炎的一种类型,也是慢性肾盂肾炎患者发生慢性肾功能衰竭的主要原因之一。但是引起RN的主要因素乃是膀胱输尿管返流(vesicoureferol reflax简称VUR)所致,VUR是一种较常见的现象,特别在婴幼儿时期,当VUR引起典型的肾疤痕形成时,才被称为RN,故肾疤痕是发生RN的标志。近20年来在小儿科和内科领域内虽然加以重视,但由于RN的发病特点及诊断条件的限制,对该病的诊断率偏低,对其认识亦不够充分,有些问题有待进一步研究。 Reflux Neprobiology (RN) is a type of chronic pyelonephritis and one of the major causes of chronic renal failure in patients with chronic pyelonephritis. However, the main cause of RN is caused by vesicoureferol reflax (VUR). VUR is a common phenomenon, especially in infants and young children, when VUR caused typical renal scar formation, it is called RN, so kidney scar is a sign of RN. Although attention has been paid to the pediatric and internal medicine fields in the past 20 years, the diagnosis of the disease is low due to the characteristics of the onset of RN and the limitations of the diagnostic conditions, and its understanding is not sufficient enough. Some problems remain to be further studied.
