NCT ID: NCT02986477 Withdrawn - Clinical trials for Vesico-Ureteral Reflux

Clinical Applications of Contrast-Enhanced Ultrasonography in Pediatric Population - Intravesicle Administration

Start date: January 1, 2017
Phase: N/A
Study type: Interventional

In children, specifically the intravesicle administration to study vesicoureteral reflux in children already catheterized and scheduled for voiding cystourethrogram (VCUG). Contrast-enhanced ultrasonography is a tremendous advancement from conventional B-mode and color Doppler ultrasonography, as it permits noninvasive, non-ionizing delineation of physiology and pathophysiology with higher resolution and accuracy in children. The technique is particularly useful in pediatric population whose lifetime risk of cancer significantly increases with higher frequency of ionizing radiation. Voiding cystourethrogram is a fluoroscopy technique that can study reflux real time but at the risk of radiation side effects. In this regard, intravesicle administration of ultrasound contrast agent can help avoid radiation in children and potentially replace the conventionally used voiding cystourethrogram.

NCT ID: NCT01137929 Withdrawn - Clinical trials for Vesicoureteral Reflux

Bacterial and Host Genetic Risk Factors in Acute Pyelonephritis

Start date: November 2014
Phase: N/A
Study type: Observational

No single host or pathogen trait identified by previous research can be correlated with all cases of childhood acute pyelonephritis or APN (i.e., kidney/upper urinary tract infections) and APN-associated renal scarring (the outcome with the highest morbidity), making it difficult for physicians to determine which patients will be affected. Our proposal is to comprehensively study the relationships between the clinical manifestations of urinary tract infections (UTIs), the host risk factors and immune response, and the microbial species that cause these conditions. The result of the study will be a clinical severity score to personalize diagnostic and treatment strategies for infants with UTI, with the goal of decreasing the morbidity of APN/renal scarring and improving patient outcomes.

NCT ID: NCT00830479 Withdrawn - Clinical trials for Vesicoureteral Reflux

Study of Endoscopic Versus Open Surgery for Urinary Reflux

STRETCH
Start date: January 2009
Phase: N/A
Study type: Interventional

This study seeks to compare outcomes after anti-reflux surgery (ARS) for correction of low-grade vesicoureteral reflux (VUR). It is a randomized controlled open-label trial of conventional open anti-reflux technique versus endoscopic anti-reflux technique with injection of dextranomer/hyaluronic acid copolymer (Deflux). Primary endpoint will be resolution of VUR at initial cystogram after ARS. Secondary outcomes will include incidence of postoperative UTI, resolution of VUR at 1-year cystogram after ARS, surgical complications, and quality of life measures after ARS.

NCT ID: NCT00752375 Withdrawn - Pyelonephritis Clinical Trials

Antibiotic Prophylaxis in Children With Pyelonephritis

Start date: February 2009
Phase: Phase 3
Study type: Interventional

Children who present with pyelonephritis undergo many investigations, and long term care to prevent renal damage. The focus is primarily on preventing renal failure however along the way and particularly with children, other issues arise which impact their lives, as well as their family's lives. Parents are concerned about subjecting their children to invasive procedures and long term antibiotic use, particularly if they are not sure of the benefit. This study seeks to provide information on the impact of investigation and long term antibiotic treatment in reference to long term health and quality of life in children who present with febrile urinary tract infections in the absence of anatomic abnormalities.
