<s>[INST] I had a Hysterectomy in August of 2009, which resulted in a stitched off Ureter and subsequent Nephrostomy bag and Ereteral repair/replace.  I'ts been 1 1/2 years of repeated urinary Strep B infections (about every 4-6 weeks).  Just a few weeks ago, the right kidney became very tender, I have been purely exhausted, swelling of hands and tingling. Urologist performed renal ultrasound and VCUG which confirmed Grade 3 Reflux and mild Hydronephrosis of BOTH kidneys. The subsequent Mag 3 Renal scan with Lasix showed as "normal".  My question is...I've asked the doctor for blood tests to make sure my kidneys are functioning normally and he is refusing.  Am I way off base for asking for the blood test? (i.e. Creatinine level, GFS, metabolic panel, etc).  Please help [/INST] You may have undergone ureteral reimplantation , which causes some degree of VUR but severe VUR is not good . You may need to undergo repeat surgery with better technique . Serum creatinine usually rises  very late. </s>
