“…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.…”

“…The incidence of ANH is 1%−5% of all pregnancies [1][2][3][4]. Most cases of ANH are transient hydronephrosis (64%) [4], which usually resolves after postnatal follow-up ultrasound [4][5][6][7][8]. 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.…”

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.

ObjectivesMercapto acetyl tri‐glycine renogram (MAG3) scan has been the gold standard assessment of pediatric ureteropelvic junction obstruction (UPJO) but requires intravenous access and radiation exposure. While Doppler ultrasound measurements of resistive indices (RI) of the arcuate arteries have been proposed as an alternative assessment of obstruction, they have not been widely adopted in the pediatric population. We hypothesized that RI of the main renal artery (RA) is more strongly correlated with MAG3 findings than arcuate RI.MethodsPediatric patients with unilateral Society for Fetal Urology grade 3–4 hydronephrosis undergoing concomitant RUS and MAG3 were recruited. Doppler ultrasound peak systolic velocity (PSV); RI of bilateral RA at the origin, middle, and hilum; and RI of the superior, middle, and lower pole arcuate arteries were obtained. MAG3 differential renal function (DRF) and T½ were recorded. Differences in RI measurements (DRI) between the affected and normal kidney were calculated and compared with DRF and T½.Results31 patients (median 4.6‐month‐old) were enrolled. Only RA RI at the origin differed between affected and normal kidneys (p < .001). DRI RA at the origin showed weak evidence for an association with MAG3 DRF < 40% (p .07). DRI was not associated with T½ > 20 minutes.ConclusionThere was weak evidence for an association between RA DRI at the origin and DRF but not with T½. These findings suggest that RA DRI may provide additional data in the evaluation of patients with UPJO to tailor the use of MAG3 and associated risk of radiation exposure to those patients most at risk for concomitant renal function impairment.
