BACKGROUND Endoscopic correction of vesicoureteral reflux (VUR) in children offers minimally invasive management and is widely used as a first-line procedure for all grades of reflux. However, there is debate about which tissue-augmenting substance is the best to use. The aim of this study was to evaluate the efficacy of two bulking substances, Deflux (Dx/HA) and Vantris (PPC), for endoscopic t...
Vesicoureteral reflux (VUR) is one of the most common diseases in pediatric urology and classified into primary and secondary VUR. Although posterior urethral valve (PUV) is well known as a cause of the secondary VUR, it is controversial that minor urethral deformity recognized in voiding cystourethrography represents mild end of PUV spectrum and contributes to the secondary VUR. We have been s...
Background: Routine diagnostic methods of Vesicoureteral reflux (VUR) are invasive and can cause exposure to radiation and may increase risk of urinary tract infections. Therefore, introducing reliable, non invasive methods might be more interested in pediatric nephrology. The objective of this perspective case control study was to evaluate the prognostic value of urinary neutrophil-gelatinase ...
OBJECTIVES The objective of this monograph is to familiarize the reader with dynamic hydrodistention classification of the ureter and Hydrodistention Implantation Technique (HIT) methodology for the endoscopic correction of vesicoureteral reflux (VUR). The indications, current success rates, complications, and potential future applications of these methods are reviewed. METHODS Hydrodistentio...
Background: Imaging modalities such as voiding cystourethrography (VCUG), direct radionuclide cystography (DRNC), and renal cortical scintigraphy (RCS) with technetium-99m dimercaptosuccinic acid (Tc-99mDMSA), are helpful in detecting possible abnormalities of urinary tract such as vesicoureteral reflux (VUR). However, there are confounding data regarding the preference of these modalities. In ...
OBJECTIVE To evaluate the frequency of urinary tract infections (UTIs) and degree of renal parenchymal damage as well as the parameters of growth, development and nutritional status in antenatal hydronephrosis cases with vesicoureteral reflux (VUR). METHODS Infants, whose antenatal ultrasonography (US) showed a fetal renal pelvic diameter of 5 mm or greater were investigated. Of the 277 infan...
PURPOSE The aim of this study was to investigate the urinary concentration of epidermal growth factor (EGF) and monocyte chemotactic protein-1 (MCP-1) as reflux nephropathy (RN) biomarkers before and after endoscopic treatment of moderate to severe vesico-ureteral reflux (VUR). MATERIALS AND METHODS A prospective study was carried out on 72 children with moderate to severe VUR. All patients u...
RET, a tyrosine kinase receptor essential for kidney development, has recently been shown to be important for the formation of the urinary tract. When RET is overexpressed in the HoxB7/Ret transgenic mouse, kidneys are small and cystic, and in some of the mice, the ureters are grossly dilated. Here, we report that the observed ureteral dilatation is associated with the urinary tract abnormality...
BACKGROUND Vesico-ureteral reflux (VUR) is a dynamic event in which a retrograde flow of urine is present into the upper tracts. VUR may occur isolated or in association with other congenital abnormalities or as part of syndromic entities. We present a patient with a bilateral primary VUR, syndromic disease caused by a large deletion of 18q (18q21.3-qter) and terminal duplication of 1p (1p36.32...
OBJECTIVE To evaluate an outcome of endoscopic correction of vesicoureteral reflux (VUR) using Vantris (Promedon, Cordoba, Argentina) in terms of its effectiveness and morbidity in a multicenter study. MATERIALS AND METHODS From 2009 to 2013, 611 patients (210 boys and 401 girls) with a mean age of 3.56 years (range, 1 month-18 years) were treated at 7 centers worldwide endoscopically with Va...
