Background Fetal hydronephrosis is a common urinary tract anomaly that may result in renal parenchyma damage. Ultrasound is considered a simple, noninvasive procedure to diagnose and track antenatal hydronephrosis. Our aim was to study the clinical course of fetal hydronephrosis in fetuses. Materials and Methods</...

OBJECTIVE Antenatal hydronephrosis is diagnosed in 1% to 5% of all pregnancies; however, the antenatal and postnatal management of hydronephrosis varies widely. No previous studies define the risk of postnatal pathology in infants with antenatal hydronephrosis. Our objective was to review the current literature to determine whether the degree of antenatal hydronephrosis and related antenatal ul...

Background The aim of this study was comparison characteristics of family and demographics of children with antenatal hydronephrosis, in 2nd and 3rd trimester of pregnancy, in order to the need for postnatal management. Methods This cross-sectional study described some information from family of children with antenatal hydronephrosis, at the Pediatric Urology Research Center of Children's Hos...

Antenatal hydronephrosis and vesicoureteral reflux (VUR) are common renal tract birth defects. We recently showed that disruption of the Robo2 gene is associated with VUR in humans and antenatal hydronephrosis in knockout mice. However, the natural history, causal relationship and developmental origins of these clinical conditions remain largely unclear. Although the hydronephrosis phenotype in...

Objectives: To describe the maternal and fetal characteristics of isolated antenatal hydronephrosis (ANH), to address parental concerns by providing local data based on the fetal renal pelvis anteroposterior diameter (APD), and to determine the most effective APD cutoff in the second and third trimester for prediction of postnatal urological outcome. Methods: A retrospective review of all cases...

Widespread use of fetal ultrasonography is accompanied by more frequent detection of antenatal hydronephrosis. Therefore, sonographic evaluation of neonates with a history of antenatal hydronephrosis is becoming more widespread. As an initial postnatal non-invasive imaging modality, ultrasonography is used to screen for persistence of hydronephrosis, determine the level and severity of obstruct...

background & aim: we aimed to describe a standard survival analysis, so that we can analyze some factors related to the time of occurrence of different types of reflux (unilateral-left, unilateralright, and bilateral) in children with antenatal hydronephrosis (anh) and to provide an approach taking competing risks into account. methods & materials: we used data of 193 children that was collecte...

We reviewed the outcome of fetal hydronephrosis with a renal pelvic dilatation (RPD) of 4-7 mm to assess whether a RPD > 7 mm had a higher predictive value for renal pathology. 373 fetuses were diagnosed with hydronephrosis giving an incidence of 2.2%. The male: female ratio was 1.8:1. 5(1.34%) fetuses with antenatal hydronephrosis were diagnosed with Down Syndrome. 299 (91.7% fetuses with an R...

Detailed antenatal sonography was performed on 18766 pregnant women between 1990 and 1994. Antenatal hydronephrosis, defined as an antero-posterior diameter of the renal pelvis (APPD) greater than 5 mm, was detected in 100 cases (0.59%). Sixty four infants had postnatal hydronephrosis at one and/or six weeks after delivery; 21 of these had urological anomalies. Twelve infants had vesico-ureteri...
