[Localizationstudies in female patients with recurrent urinary tract infection. I. Patients without ureterovesical...

In 16 girls and 12 women with recurrent urinary tract infection without ureterovesical reflux we performed 75 bladder washout-tests. 52 (72%) tests indicated a vesical, 19 (27%) of supravesical bacteriuria. The 16 girls had less often (18%) supravesical bacteriurias than the 12 women (58%). If follows that in the absence of reflux, ascension of bacteria from the bladder to the upper tract is a relatively frequent phenomenon, the pathogenic importance of which is not yet clear. Clinical manifestations and urographic aspect correlated rather poorly with the results of the bladder-washout-test.
