A large number of hydronephrotic kidneys (108) were diagnosed prenatally in 69 infants between 1987 and 1991 and subsequently confirmed postnatally. Prenatal morphometric measurements were done in order to find reliable parameters for the detection of a group at risk for surgical treatment. A second aim of the study was to describe the natural history and management of hydronephrosis detected prenatally. We devised a classification of postnatal obstructive uropathy using ultrasonography and the renal scan. Accordingly, we classified the patients as having mild, moderate or severe hydronephrosis. A renal pelvic antero-posterior diameter (APD) of 9 mm or more, and a pelvic-to-renal APD ratio of 0.45 before 32 weeks of gestation and 0.52 thereafter, were found to be useful for the detection of severe outcome. Our new parameter, a pelvic-to-renal volume ratio of greater than 0.08, can also be used for this purpose.
1987年至1991年间，69例婴儿在产前被诊断出大量肾积水（108例），随后在出生后得到证实。进行产前形态测量是为了找到可靠的参数，以检测出有手术治疗风险的群体。该研究的第二个目的是描述产前检测出的肾积水的自然病史和处理方法。我们利用超声检查和肾扫描制定了一种产后梗阻性尿路病的分类方法。据此，我们将患者分为轻度、中度或重度肾积水。发现妊娠32周前肾盂前后径（APD）为9毫米或以上，以及肾盂与肾脏APD比值为0.45，妊娠32周后为0.52，有助于检测严重后果。我们的新参数，即肾盂与肾脏体积比大于0.08，也可用于此目的。
