Hi Doc, I had a transparent stone 1.7 cm in the kidney 4 months ago and it moved till it obstructs the ureter making mild hyderonephrosis, I underwent an operation to fix a DJ scent and taking URALYTE U granules for 2 months, after two months, I suffered from constant bleeding and the Urologist told me that I should remove the scent because it made cystitis in the bladder . I already got it removed, and after two weeks i made an ultrasound which indicates that there is mild fullness of the same kidney confirming that there is improvement and no blockage. now I d like to know reason for such a mildness especially that I drink much water and boiled barely and have some tolerable pain on both sides !!!!Following up after the Doc s answer!!!! I had the stone in my right kidney, and after the removal operation, Ultrasound specialist said I have mild fullness within the pelviccalyceal and proximal part of ureter with much improvement... my questions now: what should I do and how to know accurately the reason for this fullness? is such fullness dangerous on my kidney? Should I make IVR image? Thanks much
