Vesico-ureteral reflux. I. Renal function and morphology in relation to anamnestic and urodynamic parameters

Hundred and one children aged 12 years or less were consecutively referred with non-neurogenic vesico-ureteral reflux. None of the patients were previously operated for reflux. Based on the degree of reflux and the degree of nephropathy judged from urograms or renoscintigrams the patients were assigned an index defined as the sum status of both nephro-ureteric units. We found no correlation between VUR index, nephropathy index and GFR on one side, and bladder function parameters (spontaneous voiding, cystometry, bladder activity during sleep) on the other. Further, no correlation was found to history concerning urinary tract infections or enuresis the year before admittance. Possible reasons for the lack of correlation are discussed.
