I was recently in the ER with stomach pain in my right side. bloodwork showed high wbc and the dr said ct showed lymphnodes in abdomen swollen. I went and picked up my cat scan report and it didnt say anything about lymphnodes but it did say i had a right extrarenal pelvis in borderline mild right hydronephrosis without a clear etiology. I was told i had this about ten years ago and since then I have had this re-occur several times. Should I be concered about this being ongoing for so long?
You should get a radionuclide scan like DTPA Venography before and after lasix (diuretic injection to know if the enlarged renal pelvis is due to obstruction or is just an extra renal pelvis without obstruction which doesn't require any treatment.
