INTRODUCTION: Symptomatic pediatric ureterocele has diverse manifestations, making evidence-based management impractical. Thus, detailed visualization of ureterocele anatomy prior to first surgical incision is invaluable. Retrograde ureterocelogram (RUC) is a simple, underutilized radiologic technique that can be performed during cystoscopy. This study sought to determine whether RUC changes surgical management by more accurately depicting the complex ureteral and ureterocele anatomy, compared with renal ultrasound (US) and voiding cystourethrography (VCUG)...

OBJECTIVE: Our institutional protocol for the treatment of exstrophy-epispadias complex includes routine endoscopic and cystographic evaluation of the bladder with the child under general anesthesia. The protocols briefly described in the literature include a cystographic evaluation and the measurement of bladder capacity, but there are no reports on concurrent endoscopic findings and the value of examinations in this setting. Our objective is to evaluate the role and necessity of our management protocol by reviewing the findings in our patients' medical charts...

Urine dipsticks have to be used more frequently for the screening of urinary tract infections (UTI) in febrile infants and children (grade A). Confirmation of the UTI by urine culture should prefer other methods of sampling than the urine bag: sampling jet, urethral catheterization, or pubic puncture (grade A). The percentage of Escherichia coli producing extended-spectrum beta-lactamases (ESBL) in children accounts for less than 10 % in France and does not justify revising the 2007 recommendations (grade B)...

Pyelonephritis is a common bacterial disease in young children and is a serious infection because of its potential to produce renal scarring. One of the concerns of physicians is therefore the diagnosis of uropathy at risk for recurrence of pyelonephritis, especially high-grade reflux. There are no French recommendations on imaging evaluation after a first episode of pyelonephritis. Voiding cystography was systematically proposed years ago and recommended by the American Academy of Pediatrics until 1999. This systematic strategy exposed all children to a painful, irradiating exam, and exposed them to urinary tract infection...

INTRODUCTION: Both, fluoroscopic voiding cystourethrography (fVCUG) and direct isotope cystography (DIC) are diagnostic tools commonly used in pediatric urology. Both methods can detect vesicoureteral reflux (VUR) with a high sensitivity. Whilst the possibility to depict anatomical details and important structures as for instance the urethra in boys or the detailed calyceal anatomy are advantages of fVCUG, a lower radiation burden is thought to be the main advantage of DIC. In the last decade, however, a rapid technical evolution has occurred in fluoroscopy by implementing digital grid-controlled, variable rate, pulsed acquisition technique...

The upper urinary tract forms as a consequence of the reciprocal inductive signals between the metanephric mesenchyme and ureteric bud. A clue to the timing of events leading to an abnormality of the upper urinary tract can be the presence also of associated anomalies of internal genitalia since separation of these systems occurs at about the 10th week of gestation. Prenatal sonography has facilitated the detection of urological abnormalities presenting with hydronephrosis. Hydronephrosis suggests obstruction, but by itself cannot be equated with it...

Conventional pediatric cystography, which is based on diagnostic X-ray using a radio-opaque dye, suffers from the use of harmful ionizing radiation. The risk of bladder cancers in children due to radiation exposure is more significant than many other cancers. Here we demonstrate the feasibility of nonionizing and noninvasive photoacoustic (PA) imaging of urinary bladders, referred to as photoacoustic cystography (PAC), using near-infrared (NIR) optical absorbents (i.e. methylene blue, plasmonic gold nanostructures, or single walled carbon nanotubes) as an optical-turbid tracer...

OBJECTIVE: To evaluate the yield, economic, and radiation costs of 5 diagnostic algorithms compared with a protocol where all tests are performed (ultrasonography scan, cystography, and late technetium(99)dimercaptosuccinic acid scan) in children after the first febrile urinary tract infections. METHODS: A total of 304 children, 2 to 36 months of age, who completed the diagnostic follow-up (ultrasonography, cystourethrography, and acute and late technetium(99)dimercaptosuccinic acid scans) of a randomized controlled trial (Italian Renal Infection Study 1) were eligible...

Urinary tract infections (UTIs) are one of the most common sources of bacterial infections among young febrile children. Accurate diagnosis of acute pyelonephritis (APN) and vesico-ureteral reflux (VUR) are important because of their association with renal scarring, sometimes leading to long-term complications. However, the gold standard examinations are either a DMSA scan for APN and scarring, or cystography for VUR, but both present limitations (feasibility, pain, cost, etc.). Procalcitonin, a reliable marker of bacterial infections, was demonstrated to be a good predictor of renal parenchymal involvement in the acute phase and in late renal scars, as well as of high-grade VUR...

Management of urinary tract infections (UTI) in children is at a crossroads both in regard to the diagnostic methods used, the need to detect vesico-ureteral reflux, the benefit of prophylactic antibiotics and the emergence strains of multiresistant E. coli. The Groupe de Pathologie Infectieuse Pédiatrique of French Society of Pediatrics takes position : (i) to utilize more frequently urinary dipsticks and for urinary cultures, other methods of urine sampling than bag (sample jet, urethral catheterization, supra-pubic puncture) ; (ii) do not alter the initial therapeutic proposals of the former AFSSAPS (despite the percentage of E...

Residual giant-cystic craniopharyngiomas are amenable to intracavitary bleomycin treatment. Radiologic identification of potential cyst leaks is of paramount for treatment decisions. This report describes our experience in the use of intracystic Gadolinium (Gd)-enhanced MR imaging to determine potential communications between the tumoral cysts and other intra-axial spaces in 4 pediatric patients with residual giant-cystic craniopharyngiomas in whom intracavitary bleomycin treatment was planned after the injection of ...

BACKGROUND: Predicting vesico-ureteral reflux (VUR) ≥3 at the time of the first urinary tract infection (UTI) would make it possible to restrict cystography to high-risk children. We previously derived the following clinical decision rule for that purpose: cystography should be performed in cases with ureteral dilation and a serum procalcitonin level ≥0.17 ng/mL, or without ureteral dilatation when the serum procalcitonin level ≥0.63 ng/mL. The rule yielded a 86% sensitivity with a 46% specificity...

BACKGROUND: Urolithiasis is a frequent complication in a heterotopic reservoir and the surgical management could be a difficult problem. Open surgery is not recommended in patients with multiple previous surgeries. A less invasive technique, such as the endourologic procedures, would allow high stone-free rate and low surgical morbidity. INTRODUCTION: Stone formation in the reservoir is a well-known complication of urinary diversion. The incidence of lithiasis in patients with continent urinary diversion is reported as 12-52...

Posterior urethral valves represent a congenital barrier at the level of the posterior urethra, which opposes miction. They are located near the prostatic urethra, originating at the verumontanum level, affecting male patients. The ureters are inconstantly dilated; vesicoureteral reflux is met in 2/3 of the cases. The reflux can be secondary to the sub-bladder barrier, but it can also be considered primitive, determined by the intra bladder ectopy of the ureter. The presence of the reflux is interpreted as a severe associated factor...

BACKGROUND AND OBJECTIVES: Primary vesicoureteric reflux (VUR) can coexist with reflux nephropathy (RN) and impaired renal function. VUR appears to be an inherited condition and is reported in approximately one third of siblings of index cases. The objective was to establish a DNA collection and clinical database from U.K. families containing affected sibling pairs for future VUR genetics studies. The cohort's clinical characteristics have been described. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Most patients were identified from tertiary pediatric nephrology centers; each family had an index case with cystography-proven primary, nonsyndromic VUR...

Anton J Bueschen, Mark E Lockhart
The evolution of urological imaging has had a major impact on the diagnosis and treatment of urological diseases since the discovery of the X-ray by Roentgen in 1895. Early developments included plain films of the abdomen, retrograde urographic techniques, development of contrast media, excretory urography, renal mass puncture, renal angiography, cystography and nuclear medicine procedures. These procedures led to the maturation of the specialties of diagnostic radiology and urology, and the development of the subspecialties of pediatric urology and urological radiology during the first seven decades of the 20th century...

Kassa Darge
Voiding urosonography (VUS) entails the intravesical administration of US contrast agent (USCA) for the diagnosis of vesicoureteric reflux (VUR). VUS is now recognized as a practical, safe, radiation-free modality with comparable or higher sensitivity than direct radionuclide cystography (DRNC) and voiding cystourethrography (VCUG), respectively. An extensive review of the literature regarding both the procedural aspects and comparative diagnostic values of VUS has been published (Darge Pediatr Radiol 38:40-63, 2008a, b)...
