“…Fortunately, none of the patients had progressed to CKD/ESRD, as in similar previous studies [4][5][6][7][8][9][10][11]. However, one of our patients died because of pulmonary hypoplasia and its potential association with hydronephrosis was unclear.…”

“…This condition-which normally requires no further invasive investigation or treatment-is associated with a milder degree of ANH from AUS findings as in previous studies [4][5][6][7][8][9][10][11]. Additionally, the milder the first PUS is, the more likely the association with transient hydronephrosis.…”

“…However, some cases are pathological-mostly as a result of ureteropelvic junction (UPJ) obstruction (54.3%), vesicoureteric reflux (VUR) (8.5%), and posterior urethral valve (PUV) (5.3%) [4]-and can deteriorate and may require surgical treatment. Patients with ANH also have a higher risk for urinary tract infection (UTI) than the normal population (49%-53%) [9,10]. Prospective studies demonstrated that a more severe degree of ANH and bilateral ANH are associated with a higher risk for UTI and the need for surgical intervention [11].…”

Background: Antenatal hydronephrosis (ANH) is a condition characterized by fetal renal pelvic dilatation during pregnancy. It is detected in 1%−5% of all pregnancies. Most cases of ANH are physiological in nature, but some are pathological and can cause morbidity. Objective: To determine: (a) the causes of ANH; (b) the factors associated with complications; and, (c) the factors associated with surgical intervention. Methods: We reviewed the medical records of infants diagnosed with ANH; defined by a renal pelvic anteroposterior diameter ≥5 mm (based on antenatal ultrasonography) and being followed-up at Srinagarind Hospital. Results: Forty-six infants (32 boys and 14 girls) with ANH were identified. Over half (57%) were born in our hospital (in-hospital) with the condition. The two most common causes of ANH were ureteropelvic junction obstruction (32%) and transient hydronephrosis (22%). Of the 63 abnormal kidneys, 52% needed surgical intervention. Twenty-two patients (48%) had urinary tract infections and most had more than 1 episode. None of the 46 patients had end-stage renal disease, but one died because of lung hypoplasia during the neonatal period. The severity of ANH and time of first postnatal ultrasonography were related to medical complications, while bilateral ANH and more severe ANH were associated with the need for surgical intervention. A milder degree of ANH and postnatal ultrasound findings were significantly associated with transient hydronephrosis. Conclusion: Most cases of ANH were pathological and half required surgical intervention. Severe ANH and delayed investigation were associated with poor outcomes.

“…The structure of the fetal kidneys and measurement of the renal pelves are able to be reliably assessed. 7,8 This report describes the spectrum of fetal renal disorders encountered in a tertiary care facility and examines the utility of thresholds for RPD sufficient to warrant postnatal evaluation. The classification of the postnatal diagnoses as obstructive or nonobstructive was chosen because this reflects the need for surgical correction, an important distinction when counseling parents regarding postnatal prognosis and management.…”

“…This approach can be criticized for several reasons. First of all, prenatal US was shown to be unable to detect all children with congenital vesicoureteric reflux, the most frequent malformation associated with UTI [5][6][7]. Secondly, hydronephrosis as a consequence of uretero-pelvic junction obstruction can be diagnosed at any age of life in patients who had had normal prenatal sonograms, and can become complicated with severe infection.…”

This article is focused on the controversial topic of imaging strategies in pediatric urinary tract infection. A review of the recent literature illustrates the complementary roles of ultrasound, diagnostic radiology and nuclear medicine. The authors stress the key role of ultrasound which has recently been debated. The commonly associated vesicoureteric reflux has to be classified as congenital or secondary due to voiding dysfunction. A series of frequently asked questions are addressed in a second section. The proposed answers are not the product of a consensus but should rather be considered as proposals to enrich the ongoing debate concerning the evaluation of urinary tract infection in children.
