Current Primary Outcome Measures
 (submitted: August 17, 2013)
Rate of Treatment success [ Time Frame: 3 months, 1 year ]
Rate of complete resolution of VUR on follow-up VCUG at 3 months and 1 year.
Original Primary Outcome Measures Same as current
Change History
Current Secondary Outcome Measures
 (submitted: August 17, 2013)
  • Rate of renal scar development [ Time Frame: at 3 months, 1 year ]
    The rate of Renal scarring is defined as consistent decreased tracer activity noted in follow-up DMSA scan.
  • Length of VUR treatment related hospital stay [ Time Frame: 1 year ]
    Number of hospital days incurred related to VUR treatment, such as hospital admission on treatment period, recovery period, and subsequent admissions for complicated UTI secondary to VUR.
  • Rate of failed treatment response [ Time Frame: 3 months, 1 year ]
    Rate of VUR with resoultion noted on 3 month follow-up; however, VUR noted on 1 year VCUG follow-up. Failed treatment defined as persistent VUR or VUR grade progressed despite treatment.
Original Secondary Outcome Measures Same as current

Descriptive Information
Brief Title Polyacrylate Polyalcohol Copolymer for Vesicoureteral Reflux
Official Title Tissue Bulking Agent -Polyacrylate Polyalcohol Copolymer for Endoscopic Correction of Vesicoureteral Reflux in Children: A Comparative Study
Brief Summary Endoscopic correction of VUR has gained its popularity due to its less invasiveness, associated low morbidity and short hospital stay. Although short term follow-up had justified their efficacy; however, long term recurrence and complications following endoscopic correction were also being reported in the literatures (6). Currently, there are insufficient evidences on the efficacy and safety of biocompatible tissue augmenting materials used for endoscopic correction of VUR; particularly on the new tissue bulking agents. (6) Polyacrylate polyalcohol copolymer (PPC)-Vantris ® (Promedon, Cordoba, Argentina) is the newest tissue augmenting biocompatible Acrylics used for endoscopic correction of VUR.

Study Type Observational
Study Design Observational Model: Cohort
Time Perspective: Retrospective
Target Follow-Up Duration Not Provided
Biospecimen Not Provided
Sampling Method Non-Probability Sample
Study Population children diagnosed with primary VUR grade 2-4 from 2006-2012 treated by a single urologist with different treatment modalities- conservative continuous antibiotic prophylaxis, endoscopic correction with PPC and open ureteral re-implantation with Cohen technique.
  • Vesicoureteral Reflux (VUR)
  • Urinary Tract Infection
Intervention Not Provided
Study Groups/Cohorts
  • Vantris
    Patient who categorized as who underwent endoscopic correction procedure, were patients who under general anesthesia performed by a single experienced surgeon using a 10Fr Storz® cystoscope with PPC (Vantris®) subureteral or intraureteral injection, or a combination of both techniques, depending on the anatomy of the ureteral meatus and VUR grade.
  • Cohen reimplantation
    Patient underwent surgical management were all had ureteral re-implatation with Cohen technique done by single experienced pediatric urologist.
  • Continuous Antibiotic Prophylaxis
    Group of patient treated with conservative management were children treated with culture guided antibiotics and maintained on 1st or 2nd generation cephalosporin as continuous antibiotic prophylaxis until time of 1 year follow-up.
