BACKGROUND: Although renal colic in children in the United States remains relatively uncommon compared to in adults, its incidence has nearly doubled from 1999 to 2008. Noncontrast computed tomography (CT) is the current standard for the evaluation of suspected renal colic, given its high sensitivity and specificity. However, the greater lifetime risk of radiation-induced cancer from CT in pediatric patients has led to efforts to minimize radiation exposure. Additionally, pediatric renal colic is often recurrent, which might require multiple imaging studies during their lifetime...

INTRODUCTION: In the United States there is debate regarding the appropriate first test for new-onset renal colic, with non-contrast helical computed tomography (CT) receiving the highest ratings from both Agency for Healthcare Research and Quality and the American Urological Association. This is based not only on its accuracy for the diagnosis of renal colic, but also its ability to diagnose other surgical emergencies, which have been thought to occur in 10-15% of patients with suspected renal colic, based on previous studies...

Children with Dietl crisis often experience a delay in diagnosis, with the clinical entity being underdiagnosed. Pain is caused by compression of an aberrant artery crossing dilated kidney. Pain is often worsened after the consumption of liquids and resolves after fluid reabsorption. There are no clear criteria for evaluating ureter obstruction in childhood abdominal pain in the emergency department setting; however, it has been suggested that ultrasound may aid in the diagnosis. As renal parenchyma is typically preserved, and there is a paucity of associated urological complaints, once properly diagnosed, most patients are well served by a pyeloplasty...

PURPOSE: To investigate the meaning of ureter dilatation during ultrasonography (US) in infants for evaluating vesicoureteral reflux (VUR). MATERIALS AND METHODS: We retrospectively reviewed abdominal US images of infants who were diagnosed with urinary tract infection (UTI group) or only hydronephrosis without UTI (control group). Hydronephrosis (graded 0-4) and ureter dilatation (present or absent) were evaluated on each side with US. Voiding cystourethrography (VCUG) within 3 months time interval with US was also reviewed and VUR was graded (0-5) on each side...

OBJECTIVE: Urinary tract (UT) dilation is sonographically identified in 1-2% of fetuses and reflects a spectrum of possible uropathies. There is significant variability in the clinical management of individuals with prenatal UT dilation that stems from a paucity of evidence-based information correlating the severity of prenatal UT dilation to postnatal urological pathologies. The lack of correlation between prenatal and postnatal US findings and final urologic diagnosis has been problematic, in large measure because of a lack of consensus and uniformity in defining and classifying UT dilation...

BACKGROUND: Radiologists commonly evaluate children first diagnosed with urinary tract dilation on prenatal ultrasound (US). OBJECTIVE: To establish how North American pediatric radiologists define and report findings of urinary tract dilation on US. MATERIALS AND METHODS: A web-based survey was sent to North American members of the Society for Pediatric Radiology (SPR) from January to February 2014. Reporting practices and interpretation of three image-based cases using free text were queried...

The objective of this study was to investigate the accuracy of renal point of care ultrasound (POCUS) for the detection of hydronephrosis in children with a urinary tract infection (UTI). We prospectively included all patients with a final diagnosis of UTI who visited our pediatric emergency department between November 2009 and April 2011. Emergency physicians were encouraged to perform a renal POCUS during these visits, and a follow-up renal ultrasonography was performed by a radiologist who was blinded to the results of POCUS...

Pathology in the urinary tract is one of the most frequent queries when children are referred for an ultrasound examination. Comprehensive ultrasound examinations can answer most clinical questions of the urogenital tract with minimal patient preparation and without the use of ionising radiation. Therefore, optimised imaging protocols should be available in all radiology departments where children are examined. This review suggests a preferred imaging protocol for urogenital imaging in children and gives an overview of the different structures of the urogenital tract, the normal age-related sonographic anatomy, and gives examples of the most commonly encountered diseases of the urogenital system in children...

BACKGROUND: Ureteropelvic junction obstruction (UPJO) is a blockage occurring at the junction of the ureter and the renal pelvis. Pediatric patients with UPJO pose a diagnostic challenge when they present to the emergency department (ED) with severe recurrent abdominal pain if there is not a level of suspicion for this condition. OBJECTIVES: Our aim was to review presentation of UPJO to the ED, methods of diagnosis, and treatment of this common but often overlooked condition...

PURPOSE: We reviewed our experience with open dismembered pyeloplasty, with specific focus on the presentation and management of failed pyeloplasty in the pediatric population. MATERIALS AND METHODS: We performed a retrospective review of patients who had undergone open dismembered pyeloplasty between 1998 and 2003. All patients with less than 6 months of followup were excluded from analysis. The patients were followed postoperatively with serial ultrasounds, with renograms reserved for those patients with prolonged, persistent or worsening hydronephrosis, or recurrent symptoms during followup...

Abdominal pain is a common presenting complaint to the emergency department. Often, patients with chronic, intermittent histories of abdominal pain with multiple visits to medical providers find it difficult to be taken seriously. We describe a patient with a history of episodic abdominal pain who was found to have intermittent ureteropelvic junction obstruction after a timely ultrasound examination by the treating emergency physician.
