UNLABELLED Capabilities of color and power Doppler sonography (DS) were prospectively evaluated for diagnosis of acute pyelonephritis and for prediction of scarring by comparison with 99mTc-dimercaptosuccinic acid scintigraphy (DMSA). METHODS Fifty-seven children (mean age, 5 +/- 3 y) with acute pyelonephritis were investigated by biologic testing, DS (DS(More)
OBJECTIVE The aim of this study was to evaluate the usefulness of investigating underlying urinary tract pathology after the first episode of acute epididymitis in children with no prior urological history, and also to assess the possible predictive factors of urological disease at the time of diagnosis. METHODS Children with acute epididymitis were(More)
PURPOSE We review our initial cases of continent cystostomy to assess long-term functional results and complications after a minimum of 15 years of followup. MATERIALS AND METHODS Between 1976 and 1984, 23 continent cystostomies were performed on 15 boys and 8 girls with neuropathic bladders. Mean patient age at surgery was 8 years and 4 months (range 3(More)
UNLABELLED This study was performed to evaluate a quantitative method based on (99m)Tc-DMSA renal planar scintigraphy performed during acute pyelonephritis (APN) to detect kidneys at risk of scarring. METHODS A total of 43 children (5.8 +/- 3.6 y old [mean +/- SD]) were examined by (99m)Tc-DMSA scintigraphy during (DMSA 1) and 8 +/- 2 mo after (DMSA 2)(More)
OBJECTIVE To compare the characteristics of prenatally and postnatally diagnosed ureteropelvic junction obstruction (UPJO) in children. PATIENTS AND METHODS We reviewed the records of 74 children who underwent pyeloplasty or nephrectomy for UPJO between 1995 and 2000. The patients were divided into 2 groups: prenatally and postnatally diagnosed UPJO. In(More)
OBJECTIVE To evaluate whether contralateral meatal advancement based on the technique described by Gil Vernet decreases the risk of postoperative contralateral reflux, which may occur after a unilateral reimplantation. PATIENTS AND METHODS From January 1986 to 1997, 321 reimplantations were performed for unilateral vesico-ureteric reflux (VUR) using the(More)
MR urography (MRU) has been widely accepted as a substitute to intravenous urography for investigating children with a dilated urinary tract after preliminary assessment by US and voiding cystourethrography. Hydronephrosis is by far the main indication for MRU because upper tract dilatation is a frequent condition in infants and children. Recent advances in(More)
PURPOSE To analyze the prevalence of genitourinary malformations associated with multicystic dysplastic kidney (MCDK). PATIENTS and method: A retrospective analysis of medical and imaging records of 54 neonates who had the prenatal diagnosis of MCDK was carried out. All infants had the following examinations during their first month of life: ultrasound,(More)
To evaluate the performance of diffusion-weighted imaging (DWI) against the reference standard of gadolinium-enhanced T1-weighted imaging (Gd-T1-WI) in children. Thirty-nine consecutive patients (mean age 5.7 years) with suspected acute pyelonephritis underwent magnetic resonance imaging (MRI) including DWI and (the reference standard) Gd-T1-WI. Each study(More)
PURPOSE To describe the findings and limitations of color doppler ultrasound (CDUS) compared to enhanced CT in the evaluation of pediatric renal trauma and to determine the indications for first line imaging work up. PATIENTS AND METHODS 17 children (9 girls) aged 3 to 18 years were shown to have one or multiple post-traumatic renal lesions. All renal(More)
