PURPOSE Recently, several studies have suggested that distal ureteral dilatation is an important factor influencing the spontaneous resolution of primary vesicoureteral reflux (VUR). We evaluated the relationship between distal ureteral dilatation and the spontaneous resolution of primary VUR. MATERIALS AND METHODS The medical records of 114 patients with primary VUR maintained on prophylacti...

INTRODUCTION Vesico-ureteric reflux (VUR), reflux of urine from the bladder into the ureter and towards the kidney, is an important cause of end-stage renal failure in both children and adults. Primary VUR is considered to be a result of a disruption of the normal anti-reflux mechanism of the ureterovesical junction (UVJ). VUR is common, occurring in approximately 1% to 2% of newborns in Caucas...

We compared newly developed radionuclide cystography with conventional contrast voiding cystography (VCG) with regard to their diagnostic usefulness of intrarenal reflux (IRR) in children. Based on the imaging findings, we assessed the role of IRR in the pathogenesis of reflux nephropathy (RN). Among the ureters which revealed IRR diagnosed by radionuclide cystography, 38.9% (7 out of 18 ureter...

FIGURE 8-12 International system of radiographic grading of vesicoureteral reflux (VUR). The severity of VUR is most frequently classified according to the International Grading System of Vesicoureteral Reflux, using a standardized technique for performance of voiding cystourethrography. The definitions of this system are illustrated in Figure 8-4 and are as follows. In grade I, reflux only int...

PURPOSE Our aim was to determine association of vesicoureteral reflux (VUR) and idiopathic hypercalciuria in children with recurrent and single episode of urinary tract infection (UTI). MATERIALS AND METHODS The study group consisted of 45 children with VUR and recurrent UTI, and 2 control groups: 45 normal healthy children (control group 1) and 45 children with VUR and single episode of UTI ...

BACKGROUND The purpose of the present study is to determine the accuracy of magnetic resonance voiding cystourethrography (MRVCUG) for diagnosis of vesicoureteral reflux (VUR) in children and adolescents with recurrent urinary tract infection (UTI). MATERIALS AND METHODS During the cross-sectional study from May 2009 to June 2011, 30 patients' (60 kidney-ureter units) MRVCUG findings by 1.5 T...

PURPOSE The association of age, sex and renal parenchymal damage (RPD) in vesicoureteral reflux (VUR) is well known. We compared various factors between infants and children in a cohort of patients with primary VUR. MATERIALS AND METHODS Medical records of 147 patients diagnosed as VUR between 1997 and 2010 were reviewed. Of these children 91 (61.9%) were boys and 56 (38.1%) were girls. 99 (6...

PURPOSE The aim of this study was to evaluate the efficacy of single injection of a new non-biodegradable agent (Vantris(®)) Manufactured by Promedon, Cordoba, Argentina for treatment of vesicoureteric reflux (VUR). PATIENTS AND METHODS 38 children (11 males and 27 females) with a mean age of 5.3 ± 3.8 years underwent endoscopic treatment of VUR using Vantris. VUR was unilateral in 17 and bil...
