The RIVUR trial: a factual interpretation of our data.
Vesicoureteral reflux (VUR) increases the risk of urinary tract infection (UTI) and renal scarring. Many prospective studies have evaluated the role of antimicrobial prophylaxis in the prevention of recurrent UTI and renal scarring in children with VUR. Of these, the RIVUR trial was the largest, randomized, placebo-controlled, double blind, multicenter study, involving 607 children aged 2-72 months with grade I-IV VUR and a first or second symptomatic UTI. ⋯ No significant difference was seen in renal scarring between the two groups. However, this does not invalidate the role of prophylaxis in preventing renal scars because RIVUR and other recent prospective studies were not designed to address renal scarring as a primary study endpoint. In view of the RIVUR Trial and other studies that showed similar results, albeit in selected groups of patients, the debate on antimicrobial prophylaxis should shift from "no prophylaxis" to "selective prophylaxis" in children with VUR.
