title: [Prognostic parameters of scar progression, new scar formation and maturation in primary vesico-ureteral-renal reflux].
abstract: We analysed the data recorded for 901 children (1357 kidneys) treated for primary vesicoureteral reflux between 1973 and 1988 at our institution. The retrospective study showed a rate of 7.3% for new renal scarring and progression; analysis by reflux grade revealed progression and new scarring in reflux, 10.9% of cases with grade IV and 16.5% of cases with grade V whereas low grades (I and II) were followed by no scarring at all. A close correlation of new scarring with urinary tract infection and bladder function was demonstrated. Spontaneous resolution of reflux was observed in 33.6% of all patients and in only 2.6% of patients with grade V reflux, as against a 85.5% resolution rate in patients with grade I or II reflux. A different sex distribution was revealed in the age group under 1 year, in which 80% of the patients were boys and the resolution rate was higher than in any other age group.
