“…Color Doppler US may be useful for differentiating obstructive from non-obstructive causes of hydronephrosis in children via evaluation of ureteric jets in the bladder [ 18 , 19 ]. The frequency of ureteric jets on the affected side may be greatly reduced in comparison with the contralateral normal side in children with obstructive hydronephrosis [ 18 , 19 ]. Color Doppler is also very useful for differentiating a dilated pelvocalyceal system from prominent vessels in the renal hilum.…”

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 obstruction, and contribute to appropriate diagnosis and treatment. This review aims to provide a practical overview of the sonographic evaluation of neonatal hydronephrosis and to describe the sonographic findings of conditions associated with hydronephrosis in the newborn.

“…18 Studies have shown that there is a direct relationship between the ureteric jet and the presence of obstructing ureteric stone. [19][20][21] One of these studies showed that the ureteric jet in an obstructed ureter has less frequency, shorter duration and low peak velocity, when compared with the contralateral normal side. 20 Nevertheless, the study showed that the presence of ureteric jet did not rule out significant ureteric obstruction.…”

“…20 Nevertheless, the study showed that the presence of ureteric jet did not rule out significant ureteric obstruction. 21 This study aims primarily to investigate the accuracy of renal POCUS performed by EPs in detecting hydronephrosis in patients with renal colic. Also, we hypothesized that the presence of high grade hydronephrosis indicates an obstructive ureteric stone which will result in the absence of a ureteric jet.…”

Objectives: to determine the accuracy of renal point of care ultrasound (POCUS) performed by emergency physicians in detecting hydronephrosis in patients with renal colic. Methods: We conducted a prospective cross-sectional diagnostic study at Sultan Qaboos University Hospital, emergency department (ED), from February 2017 to October 2018. All adult patients with suspected renal colic and who can give informed consent were included. The emergency physicians perform POCUS on both kidneys and graded hydronephrosis as none, mild, moderate, or severe cases. We compared POCUS grade to non-contrast computed tomography (NCCT) grade. Results: Three hundred and three participants were enrolled in the analysis. Most of the study population are adult males, 247 (81.5%), and the mean age is 39 years. Among the samples, 71.2% of patients had a degree of hydronephrosis based on CT findings. Ultrasound performed by emergency physicians had a sensitivity of 75.8% (95% CI: 69.5‒81.4), the specificity of 55.2% (95% CI: 44.1‒65.8), the positive likelihood ratio of 1.69 (95% CI: 1.32‒2.16), and negative likelihood ratio 0.43 (95% CI: 0.32‒0.59) for hydronephrosis using CT as the criterion standard. Conclusions: When evaluating patients with suspected renal colic, a bedside renal POCUS performed by emergency physicians (EP) has a moderate sensitivity to detect hydronephrosis and grade its severity. It should be utilized in the ED to screen patients for hydronephrosis. More training is required to improve the test's accuracy, as this might help as a screening tool in ED.Keywords: Hematuria; Hydronephrosis; Nephrolithiasis; Point-of-care testing; Renal colic; Ultrasonography.

In infants and young children with suspicion of genitourinary tract anomalies, ultrasonography (USG) is usually the first imaging modality. Advantages of USG are well described. In the evaluation of complex congenital urogenital anomalies, ultrasound examination needs to be tailored according to the clinical suspicion and to yield maximum information. Primary megaureter is a congenital anomaly, which is associated with dilatation of ureter above an adynamic segment at the vesicoureteric junction (VUJ). Two different types are described in the literature: refluxing and obstructive. Absence of ureteric jet on USG in conjunction with vesicoureteric reflux (VUR) on voiding cystourethrogram (VCUG) prompts to the diagnosis of refluxing type of obstructed megaureter. Here we describe a case of duplex moiety with refluxing type of obstructed megaureter, where gray-scale USG and real-time color Doppler evaluation of the ureteric jet established the diagnosis. The aperistaltic segment of lower ureter near the VUJ with an absence of ureteric jet for the same moiety suggested the possibility of an obstructed megaureter. VUR was demonstrated on VCUG; thus, pointing toward a diagnosis of obstructed refluxing megaureter.
