[Localizationstudies in female patients with recurrent urinary tract infection. I. Patients without ureterovesical reflux (author's transl)].

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.
