Data were analyzed using the chi-square test. Criteria to select patients with vesicoureteral reflux for observation off continuous antibiotic prophylaxis remain poorly defined in the literature. Three hundred twenty-four patients underwent antibiotic prophylaxis with co-trimoxazole, with cephalexin, 44 with cefaclor, and 71 with alternative monotherapy in one hospital and 96 children underwent co-trimoxazole prophylaxis in the other hospital.

Description of technique, parental satisfaction and applications. In patients with congenital megaureter and VUR, ureters can be visible with 99mTc-DMSA scintigraphy and further imaging modalities are recommended for these patients. Published by Elsevier Inc. The plasma disaapearance clearance of DTPA, calculated using one compartement model with two late blood samples, gave similar resusults with the clearance estimated from the body disappearance curves.

Mures during the last 10 years and children diagnosed and operated with posterior urethra valves at the Surgical Clinic of the “M. UDR was computed by measuring largest ureteral diameter within the pelvis and dividing by the distance between the L1 and L3 vertebral bodies Figure. This study demonstrates for the first time in Iran. The Journal of Urology.

The recommendation for follow-up of these patients was one voiding cystoureterography VCUG each year. Voiding cystourethrogram in the diagnosis of vesicoureteric reflux in children with antenatally diagnosed hydronephrosis. Unfortunately, endoscopic treatment is not always successful and sometimes requires more than one trial to achieve similar results to that of an open reimplantation surgery.

Bacterial isolations in the urine cultures corresponded to E. A second-generation US contrast medium such as SonoVue, if available, should be the first choice as the dose required for one examination is much lower and consequently significant reduction of contrast agent cost is possible. The occurrence of IRR is dependent of the papillary morphology, intrapelvic pressure and urine flow.

Abnormalities on DMSA scan for detecting the presence of high-grade vesicoureteric reflux on MCUG examination had sensitivity, specificity, positive and negative predictive values of Prediction of vesico-ureteral reflux in children from intravenous urography films.

Of the kidneys evaluated, showed slight hydromephrosis in the echography. The aim of this study is to assess the accuracy of a new US examination: Full Text Available Objective: The”top-down approach” TDA aims at restricting the number of voiding cystourethrograms VCUGs and its associated morbidity while identifying patients with clinically-significant reflux. We hypothesized that reflux occurring earlier during bladder filling increases the duration of exposure of the kidneys to bacteria, and, therefore, increases the risk of pyelonephritis.

Hydronephrosis, ureter dilatation, and VUR were then compared between the two groups.

The association between the presence and grade of vesicoureteral reflux with the causal microorganism of the urinary tract infection was analyzed. In 64 children mean age 6. Because we now understand that sterile VUR is benign and most reflux spontaneously resolves over time, the initial approach in majority of children is non-surgical with continuous antibiotic prophylaxis CAP and correction of bladder and bowel dysfunction.

Children with VUR group 1 vs. Vesicoureteral reflux as a cause of hypertension, while commonly described in pediatric populations, is less prevalent in the adult population especially in the absence of proteinuria. Whether to give prophylactic antibiotics or not would ultimately need a shared decision-making involving both the treating physician and the parents assessing both the risks and the benefits.

As it becomes more apparent that there is tremendous clinical variation within grades of VUR, the need to distinguish clinically significant from insignificant disease grows. One- and vesicourreteral graft survival vesicoureterral patients with VUR was The studied group comprised male children diagnosed with vesicoureteral reflux their ages ranking between 0 years, admitted to the Pediatric Clinic, Tg.

The review included results of radiological investigations and kidney function tests. Management vesicoureteraal screening of primary vesicoureteral reflux in children. Histological findings confirmed inflammation at treated side. The significant difference was found among the curves using the log rank p vesicoureteral reflux only after the occurrence of urinary tract infection in our country. However, the use ve novel fuels and complex flows have increased the concern about flashback, especially for the use of syngas and highly hydrogen enriched blends.

Linear regression showed a significant downward trend in the average total number of antireflux operations per institution during the study period. In the evaluation of the remaining 17 ureters of patients, congenital reflujp was present in three patients.

Evaluation of renal function in children with vesicoureteral reflux. Data of vdsicoureteral who were examined by dimercaptosuccinic acid DMSA scintigraphy between and were evaluated retrospectively. We retrospectively evaluated 9 females and 61 uncircumcised males diagnosed with primary vesicoureteral reflux before age 1 year who had persistent reflux on followup voiding cystourethrogram and were subsequently followed under active surveillance without continuous antibiotic prophylaxis.

Full Text Available Purpose. In order to improve the accuracy of the grading of vesicoureteral reflux VURreference values for vesicouretteral diameter at micturition cystourethrography MCUG were established in infants and children with low-risk VUR.

The degree of dilatation in Barrett’s esophagus is currently unknown.
