Asymptomatic bacteriuria in schoolgirls. VII. A follow-up study of the urinary tract in treated and untreated schoolgirls with asymptomatic bacteriuria

Abstract

The urinary tracts of 116 schoolgirls with asymptomatic bacteriuria detected at screening were investigated by excretory urography and micturition cystourethrography. Three years later the studies were repeated in 11 patients with scarred kidneys, 11 patients with unscarred kidneys plus reflux, and 14 untreated patients with radiologically normal urinary tracts. Exceptionally small scarred kidneys showed little growth. Unscarred kidneys with vesico-ureteral reflux exhibited normal growth, as did unscarred kidneys in untreated patients. The risk of kidney damage developing as a result of asymptomatic bacteriuria in a schoolgirl with a radiologically normal urinary tract seems to be small.
