We present here a few basic proposals for algorithms and procedures for imaging the paediatric genitourinary tract based on initial discussion at a paediatric uroradiology symposium and proposals of the ESUR Paediatric Uroradiologic Guidelines Subcommittee. These recommendations were developed in the light of new knowledge that might influence existing(More)
No US contrast agent (US-CA) is currently licensed for use in children. To survey the off-label use in children of a second-generation US-CA. Questionnaires were e-mailed to European paediatric radiologists, who were asked about their experience with the second-generation US-CA Sonovue® (Bracco, Milan, Italy). Number of examinations per indication and(More)
The imaging and procedural recommendations as elaborated by the ESPR Paediatric Uroradiology Taskforce and the ESUR Paediatric Uroradiology Working Group were presented and discussed at the first uroradiology panel held during the ESPR Annual Congress in Barcelona in 2007. These recommendations were published in this journal [1] and have gained wide(More)
The aim of this study was to evaluate the accuracy of three-dimensional ultrasound distance and volume measurements using a commercially available three-dimensional ultrasound scanner. Sixty-two distance measurements were performed twice on an ultrasound tissue-mimicking phantom located in a water bath. Three-dimensional ultrasound distance measurements(More)
The aim of this study was to report our experience with transperineal ultrasound in studying the urethra, as a complementary technique to contrast-enhanced voiding urosonography (VUS). The VUS was performed in 350 patients (244 males, 106 females) less than 4 years of age, and complemented with perineal US. Ultrasound of the kidneys and bladder was obtained(More)
The aim of this study was to present current theories of pathogenesis and prognosis in urinary tract infection (UTI) and renal scarring during infancy and childhood, with special regard to new insights concerning the role of vesico-ureteral reflux (VUR). For a long time VUR and UTI were considered the only risk factors for renal scarring in childhood. Now a(More)
PURPOSE To prospectively evaluate the potential of echo-enhanced color Doppler sonography (ee-CDS) using the acoustic stimulated emission technique in the diagnosis of vesicoureteral reflux (VUR) in children. MATERIAL AND METHODS 30 children (age: 0-9 years) with suspicion of VUR were submitted for echo-enhanced cystosonography (ee-CS) and conventional(More)
Our objective was to assess the prevalence and history of arteriovenous fistula after renal biopsy in pediatric patients by the use of color Doppler sonography. Fifty patients, aged 6 days to 18.5 years, underwent sonographically guided renal biopsy. Color Doppler sonography was performed prior to, during, and after the procedure. Postbiopsy hematoma was(More)
There is a large range of benign and malignant renal neoplasms. This article lists the most benign, indeterminate and malignant renal tumours that occur during infancy and childhood. It briefly describes the most important entities, including their imaging features, and important complications. Differential diagnosis and pitfalls are discussed, and a brief(More)
Recent years have witnessed major strides in imaging modalities, including US and contrast-enhanced voiding urosonography, fluoroscopy, CT and MRI, and these have significantly impacted paediatric uroradiology. The trend is towards reduced or no radiation exposure and combined morphological and functional imaging. This review presents the currently(More)
