The postnatal imaging of infants with antenatally detected mild hydronephrosis remains controversial.
Our aim was to establish the role and timing of micturating cystourethrography (MCUG) in mild hydronephrosis.
We performed a retrospective study of 61 infants (122 kidneys) referred with an antenatal diagnosis of hydronephrosis who showed persistent postnatal dilatation. All had follow-up postnatal ultrasound (US) and MCUG performed. The degree of dilatation at each follow-up scan was recorded.
Of the 122 kidneys, 65 showed mild hydronephrosis. A substantial proportion of these (21.5%) demonstrated reflux. Serial US of these infants showed that the 6-week scan was the most informative and that any changes that warranted further investigation had occurred by this time.
We recommend that all infants with mild hydronephrosis should undergo MCUG. MCUG need not be delayed until 3 months but could be performed following a 6-week US scan.
产前检测出轻度肾积水的婴儿产后影像学检查仍存在争议。
我们的目的是确定排尿性膀胱尿道造影（MCUG）在轻度肾积水中的作用和时机。
我们对61例产前诊断为肾积水且产后持续扩张的婴儿（122个肾脏）进行了回顾性研究。所有婴儿均进行了产后超声（US）和MCUG检查。记录每次随访扫描时的扩张程度。
在122个肾脏中，65个显示轻度肾积水。其中相当一部分（21.5%）出现反流。对这些婴儿进行的系列超声检查显示，6周扫描提供的信息最多，且此时任何需要进一步检查的变化均已出现。
我们建议所有轻度肾积水婴儿均应接受MCUG检查。MCUG无需推迟至3个月，可在6周超声扫描后进行。
