Abstract
Endoscopic implantation of dextranomer/hyaluronic acid has proved to be an effective minimally invasive technique for correcting vesicoureteral reflux in children. There is some evidence suggesting that in addition to being less invasive, successful dextranomer/hyaluronic acid implantation compared to successful antireflux surgery is associated with fewer febrile and nonfebrile urinary tract infections. We review the clinical outcomes of 2 groups of children cured of reflux with open surgery and dextranomer/hyaluronic acid implantation to determine if a difference in clinical outcomes exists. We reviewed the charts of 43 patients who underwent dextranomer/hyaluronic acid implantation and 33 who underwent open surgery for vesicoureteral reflux. Data collected included age, gender, preoperative and postoperative grades of reflux, and urinalysis and urine culture results. Urinary tract infection was defined as any culture that grew more than 10(5) colonies of a single organism, with symptoms typical of cystitis (urgency, frequency, dysuria). A febrile urinary tract infection was defined as an infection accompanied by a temperature greater than 101.5F. Any hospitalizations for febrile episodes were also recorded. The incidence of urinary tract infection after successful open surgery (38%) was significantly higher than that observed following successful dextranomer/hyaluronic acid treatment (15%, p = 0.03). Febrile urinary tract infections occurred in 24% of the children who underwent open surgery and in 5% of those who underwent dextranomer/hyaluronic acid implantation (p = 0.02). Hospital readmissions occurred only in the group undergoing open surgery. Children successfully cured of vesicoureteral reflux with dextranomer/hyaluronic acid implantation have a lower incidence of febrile and nonfebrile urinary tract infections compared to those cured with open surgery. These findings suggest that dextranomer/hyaluronic acid implantation, when successful, may result in more favorable clinical outcomes.
