The Society for Fetal Urology (SFU) was founded in 1988 to study the postnatal evolution of prenatally detected anomalies of the urinary tract by following those neonates whose prenatal studies have brought them to medical attention while asymptomatic. The SFU has attempted to standardize methods of performing and grading the ultrasound and radionuclide examinations in this population. A system to grade upper tract dilatation or hydronephrosis (HN) imaged by ultrasound has been developed and is being used by SFU members in 36 institutions. The appearance of the calices, renal pelvis and renal parenchyma are key in determining the grade of HN and are illustrated in this article.
胎儿泌尿外科学会（SFU）成立于1988年，旨在通过跟踪那些在无症状时因产前检查而引起医疗关注的新生儿，研究产前检测到的尿路异常在出生后的演变情况。SFU试图规范对这一人群进行超声和放射性核素检查的方法及分级。一种对超声成像的上尿路扩张或肾盂积水（HN）进行分级的系统已经开发出来，并被36个机构的SFU成员使用。肾盏、肾盂和肾实质的外观是确定HN分级的关键，本文对此进行了说明。
