OBJECTIVE:   The objective of this study was to determine whether patients with isolated microtia or aural atresia have an increased prevalence of renal or cervical vertebral anomalies. DESIGN:   The study design was a retrospective medical record review. SETTING:   The setting was the following four distinct institutions: an urban tertiary care children's hospital, two urban academic medical centers, and a staff-model health maintenance organization...

OBJECTIVE: Prenatal detection of trisomy 8 mosaicism can be misleading and remains challenging in genetic counseling. Identifying cases of partial or complete trisomy 8 mosaicism will highlight the pitfalls of conventional karyotyping in prenatal amniocentesis for partial or complete trisomy 8 mosaicism. CASE REPORT: The patient was born uneventfully at term to a healthy 34-year-old mother. Analysis of the amniotic fluid (AF) cells showed a normal male karyotype...

OBJECTIVES: We performed a meta-analysis to examine the performance of second-trimester (14-24 weeks' gestation) isolated fetal pyelectasis as a marker for trisomy 21 and to calculate its associated weighted pooled likelihood ratios. METHODS: PubMed, Ovid MEDLINE and Cochrane databases were searched using the terms 'pyelectasis' and 'pelviectasis'. Studies were included if fetuses with isolated pyelectasis were reported separately from fetuses with other soft markers of aneuploidy and/or structural anomalies and if knowledge of the fetal karyotype was unknown at the time of ultrasound examination...

Routine use of ultrasound (US) in antenatal screening has increased over the past decade among both low- and high-risk pregnancies. Recognition of common US imaging pitfalls and artifacts associated with frequently encountered fetal anomalies on obstetric US is imperative to avoid misdiagnosis. The purpose of this article is to present practical tips on how to accurately diagnose 6 fetal anomalies including choroid plexus cyst, mild ventriculomegaly, echogenic intracardiac focus, prominent thymus, mild renal pelviectasis, and echogenic bowel...

BACKGROUND: This study was planned to evaluate the efficiency of the 11-14 week scan in detecting fetuses with major fetal structural abnormalities. METHODS: Some 1,290 pregnant women were submitted to a routine ultrasound scan between the 11th and 14th week after the detection of the fetal viability. The fetal anatomy was examined transabdominally, and in suspected cases transvaginally. Following the scans, the patients were examined in the second or third trimester of pregnancy...

REVIEW

We present two siblings with severe laryngomalacia requiring surgical intervention during the newborn period, microcephaly, developmental delay, cleft palate, preaxial polydactyly, dysplastic nails and conductive hearing loss (persistent after tympanostomy tube placement). In addition the girl has microopthalmia and the boy was born with a patent ductus arteriosus, mild pelviectasis, and hypospadias. This combination of multiple congenital anomalies has not been described previously and may represent a previously undescribed syndrome with autosomal inheritance...

The aim of this study was to evaluate the incidence of urinary tract infection (UTI) in newborns with asymptomatic, unexplained indirect hyperbilirubinemia in the first two weeks of life. Jaundiced infants, otherwise clinically well, less than two weeks of ages, with a total bilirubin level above 15 mg/dl were eligible for the study. A bilirubin work-up including glucose-6-phosphate dehydrogenase (G-6 PD) level, as well as urinalysis and a urine culture were performed in all patients. Patients with UTI, defined as more than 10,000 colony-forming units per milliliter of a single pathogen obtained by bladder catheterization, were evaluated for sepsis...

Idiopathic antenatal hydronephrosis (IAHN), defined as antenatal hydronephrosis not associated with other morphologic renal tract abnormalities, is the most common abnormality detected by antenatal ultrasound. We performed a systematic review and meta-analysis to determine the outcome of IAHN. We screened three databases and bibliographies to identify English-language original peer-reviewed papers that reported serial postnatal renal ultrasonography in children with IAHN. Patients who stabilized and/or improved were extracted and pooled according to the individual grading systems used by each study...

PURPOSE: To determine the prevalence and morphologic associations of precaval right renal arteries at spiral computed tomography (CT). MATERIALS AND METHODS: The authors retrospectively reviewed 186 arterial phase contrast material-enhanced spiral CT scans of the abdomen (5.0-mm section thickness in 97 scans, 2.5 mm in 89 scans) obtained during a 2-year period to identify patients with precaval right renal arteries. During routine interpretation of CT scans at daily readout, the authors prospectively identified 39 additional patients with precaval right renal arteries...

OBJECTIVE: To define the clinical outcome in isolated antenatal hydronephrosis (ANH), defined as pelviectasis without vesicoureteral reflux or urinary tract obstruction. STUDY DESIGN AND PATIENTS: We analyzed prospectively gathered data from patients with isolated ANH. Pelviectasis, graded using the anterior-posterior diameter reference criteria, was defined by the status of the more severely affected kidney. Urinary tract obstruction was ruled out by diethylenetriamine pentaacetic acid scan when clinically indicated...

Standardized evaluation of all newborns with antenatally recognized hydronephrosis (ANH) at The Hospital for Sick Children (HSC) has included voiding cystourethrography (VCUG). This paper reviews this protocol to determine: (1) the prevalence of vesicoureteral reflux (VUR) in isolated ANH and (2) the value of performing VCUG in cases of mild hydronephrosis, defined as renal pelvis dilatation <10 mm on postnatal ultrasonography (US). A retrospective chart review was performed on infants referred with ANH...

OBJECTIVE: This study was designed to assess interobserver variability in identifying the rim and comet-tail signs and to determine the clinical utility of these signs in determining whether or not the calcifications with which they are associated represent ureteral calculi. MATERIALS AND METHODS: Two radiologists and a radiology resident, unaware of the final diagnosis, reviewed preselected helical CT images from renal stone examinations in patients with 65 indeterminate pelvic calcifications...

We tested the parameters of gestational age and renal pelvic anteroposterior (AP) diameter of antenatally detected pelvicaliectasis for their ability to determine insignificant postnatal renal pelvic dilatation. A retrospective analysis of 10,365 antenatal sonograms revealed 121 kidneys with pelvicaliectasis, from which 99 sonograms with sufficient postnatal follow-up were reviewed. Gestational ages were classified as <20, 20-30, or >30 weeks. Thresholds of renal pelvic AP diameter in each gestational period that were predictive of postnatal insignificance were determined to be <6, <8, and <10 mm, respectively...

Although prominent fetal nuchal folds, short long bones, echogenic bowel, and renal pelviectasis have been shown to be associated with trisomy 21, none has acceptable diagnostic efficacy. Diminished fetal ear lengths measured by ultrasound have recently been reported as yet another potential morphological marker for the prenatal detection of trisomy 21. To investigate this further, we measured ear lengths and widths of normal (n = 107) and trisomy 21 (n = 25) second-trimester formalin-preserved fetuses. The normal ear growth characteristics are described and compared with those of trisomy 21 fetuses...

PURPOSE: To correlate the radiologic and pathologic findings in patients with renal medullary carcinoma and sickle cell trait. MATERIALS AND METHODS: Radiologic studies of five pathologically proved cases of renal medullary carcinoma were retrospectively correlated with gross pathologic findings. Excretory urograms, computed tomographic (CT) scans, sonograms, photographs of the gross surgical specimens, and an angiogram were available for review. Each case was analyzed for tumor location, pattern of growth, contrast enhancement and echotexture, angiographic pattern, and stage...

Ultrasound often detects a sonolucent region in the hilum of the fetal kidney. Although this sonolucency is usually assumed to represent mild dilatation of the fetal renal collecting system, in pediatric and adult kidneys blood vessel lumina can simulate pelviectasis. We used color Doppler ultrasound to differentiate the fetal renal collecting system from hilar blood vessels and to evaluate how often blood vessels account for the sonolucent region often demonstrated in the renal hilum during antenatal sonography...
