We aimed to investigate the efficacy of postnatal ultrasonography in detecting congenital anomalies of the kidneys and urinary tract in term infants without prenatal history of congenital anomalies of the kidneys and urinary tract.
In this retrospective cohort study, we reviewed the records of term infants between six weeks and three months of age who underwent urinary tract ultrasonography during routine pediatric care.
Congenital anomalies of the kidneys and urinary tract were detected on prenatal ultrasonography in 75 of the 2620 patients included in the study. Congenital anomalies of the kidneys and urinary tract were detected via postnatal USG in 46 (1.8%) of 2554 patients without anomalies on prenatal USG screening. The most common anomaly was hydronephrosis (69.6%). Thirty-two cases of hydronephrosis, three cases of renal agenesis, four cases of horseshoe kidney, one case of MCDK, and two cases of duplex systems which were not detected on prenatal USG were detected on postnatal USG. On the other hand, 29 (1.1%) cases with mild or moderate hydronephrosis on prenatal ultrasonography did not have hydronephrosis on postnatal ultrasonography.
In our study, approximately one-third of the cases of hydronephrosis, unilateral renal agenesis, duplex systems, horseshoe kidney, and ectopic kidney were not detected in prenatal ultrasonography screening. Therefore, we believe that in addition to prenatal ultrasonography screening, postnatal ultrasonography screening of all children for urinary tract anomalies would be beneficial.
我们旨在研究产后超声检查对无先天性肾和尿路异常产前史的足月儿先天性肾和尿路异常的检测效果。
在这项回顾性队列研究中，我们回顾了在常规儿科护理期间接受尿路超声检查的6周龄至3个月龄足月儿的记录。
在纳入研究的2620例患者中，75例在产前超声检查中发现先天性肾和尿路异常。在产前超声筛查无异常的2554例患者中，46例（1.8%）通过产后超声检查发现先天性肾和尿路异常。最常见的异常是肾积水（69.6%）。产后超声检查发现了32例产前超声未发现的肾积水、3例肾缺如、4例马蹄肾、1例多囊性发育不良肾和2例重复肾。另一方面，产前超声检查有轻度或中度肾积水的29例（1.1%）患者在产后超声检查中未发现肾积水。
在我们的研究中，产前超声筛查未发现约三分之一的肾积水、单侧肾缺如、重复肾、马蹄肾和异位肾病例。因此，我们认为除了产前超声筛查外，对所有儿童进行产后超声检查以筛查尿路异常是有益的。
