A Randomized Controlled Trial on Antibiotic Prophylaxis in Children With Vesico-Ureteral Reflux...
PyelonephritisRenal ScarsThe aim of this study is to assess the effectiveness of antibiotic prophylaxis in preventing pyelonephritis and in avoiding the appearance of new scars in a sample of children under 36 months with vesico-ureteral reflux (VUR).
Randomized Intervention for Children With Vesicoureteral Reflux (RIVUR)
Vesicoureteral RefluxUrinary Tract InfectionsIn this 2-year, multisite, randomized, placebo-controlled trial involving 607 children with vesicoureteral reflux that was diagnosed after a first or second febrile or symptomatic urinary tract infecton, we evaluated the efficacy of Trimethoprim-Sulfamethoxazole (TMP-SMZ) prophylaxis in preventing recurrences (primary outcome). Secondary outcomes were renal scarring, treatment failure (a composite of recurrences and scarring), and antimicrobial resistance.
CeVUS With Intravesical Administration of OPTISON TM (Trademark) in Children
Vesico-Ureteral RefluxIn this clinical trial the investigators aim to evaluate the diagnostic feasibility and safety of ceVUS with the intravesical use of OPTISON for vesicoureteral reflux detection and urethral imaging in children.
Antibiotic Prophylaxis in Children With Pyelonephritis
PyelonephritisChildren 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.
Study of Endoscopic Versus Open Surgery for Urinary Reflux
Vesicoureteral RefluxThis 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.
Effects of Parental Holding on Pain Response in Young Children During Cystometry
Vesico-Ureteral RefluxFilum Terminale LipomaCystometry is essential for diagnosis and treatment plans by identifying the causes of lower urinary tract symptoms and objectively evaluating bladder functions in diseases such as neurogenic bladder, voiding dysfunction, and vesicoureteral reflux. Children may experience pain during this invasive procedure of inserting the urethra catheter. Furthermore, infants aged ≥ 6 months may feel pain from an unfamiliar and unnatural environment as they experience stranger anxiety. This experience can have a negative physical and emotional impact on children, and uncooperative behavioral reactions caused by pain can hinder the procedure. In this regard, parental holding is known as effective non-pharmacological procedural pain management in children. Although the International Children's Continence Society has advised performing cystometry while holding the infant as an effective non-pharmacological pain management method, there is insufficient evidence to support this. So, this study aimed to analyze the effect of parental holding on reducing pain in children during cystometry.
DVD-Based Training Program in Self-Hypnosis for Children
Vesicoureteral RefluxThe proposed study is designed to utilize a self-hypnosis DVD home-training program for parents to use with their children to teach self-hypnosis techniques for inducing relaxation and hypnotic analgesia. These relaxation techniques can be employed to manage anticipatory anxiety, distress, and pain during an invasive medical procedure, for example, voiding cystourethrography (VCUG). The study will examine the efficacy of this intervention for children undergoing VCUG procedures.
Evaluation of the Efficiency of Autologous Adipocytes Graft in Endoscopic Treatment in Vesico-Renal...
Vesico-Ureteral RefluxUrinary tract infection (UTI) is a common problem in childhood associated with vesico-renal reflux (VRR) in 25-40% of children. A persistent VRR and repeated pyelonephritis may predispose to renal scarring and chronic renal failure with an end-stage renal failure in up to 3% of children.Defining a standard behaviour facing VRR in children is not easy because of the lack of reliable evidence. Numbers of studies compare prospectively or retrospectively, medical, endoscopical and surgical treatment.Surgical techniques are effective but invasive and not free of complication. Medical treatment is submissive to a good observance. The introduction of endoscopic techniques permits to prevent UTI and new renal failure by VRR elimination. Since the beginning of the endoscopic treatment, several bulking agents have been proposed. The ideal agent should be easy to inject, stable in time and should be safe. Of course it should be at least as efficient as actual bulking agent. The use of Teflon was the first wave of success of endoscopic treatment. But sudden passion of Teflon has been darkened by the notion of migration. Since, others substances have been proposed, autologous or exogenous, resorbable or not. But none was ideal and no solutions were found facing problem of biocompatibility or long-term stability.Using adipose tissue as a bulking agent is ancient in plastic surgery and indications had known a leap forward in the last century with Coleman who introduced a new technique called "lipostructure". This technique has known a growing interest in the restoration of all volume defects in plastic surgery because of the stability of the graft. We propose to apply this technique to VRR management in children in order to combine innocuousness and efficiency.
Phase III Study of Chondrocyte Alginate Gel Suspension in Pediatric Patients With Vesicoureteral...
Vesicoureteral RefluxOBJECTIVES: I. Determine the safety and efficacy of chondrocyte alginate gel suspension in pediatric patients with vesicoureteral reflux. II. Determine the long term efficacy of this treatment regimen in this patient population. III. Evaluate the short and long term avoidance of surgery or antibiotic therapy after this treatment regimen in this patient population. IV. Estimate the risk:benefit ratio of this treatment regimen in these patients.
Clinical Applications of Contrast-Enhanced Ultrasonography in Pediatric Population - Intravesicle...
Vesico-Ureteral RefluxIn 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.
