[|Human|] during pyloneprotis stage or severe UTI infection dmsa test done and it was came that left kidney functioning 7% but now after antbiotic treatment through IV uti fully cleared now doctor told to do dmsa test again to confirm the improvement in left kidney function, female child 7 years age
[|AI|]  It depends on 2 factors :1. In what stage of the disease the earlier DMS TEST was done? Interpretation of acute scan is different from post treatment or delayed scan. 2. whether the infection was chronic or recurrent? Size of the kidney and presence of any scars influence long term management. So, after the second DMS study, you can discuss with a pediatric nephrologist about the prognosis. Also, in some cases, there may be a need to rule out vesico-ureteric reflux ;if clinically suspected.
