Hi there! I have a lower back pain and pulling in my bladder. I believe its a UTI but no results yet just a dipstick test (leukocyte 2+). Have a UTI almost every month for 15 months (no UTI in the culture only blood or leukocytes actually)... Having an MRI with contrast for abdomen scheduled tomorrow. My question is
Dear patient Recurrent UTI may affect your kidney and may lead to glomerulonephritis.  Sensitivity of ultrasound depends on experience and may not pick up renal pathology.  Before going for contrast your serum urea and creatinine must be done and allergy to contrast dye must be ruled out. If serum urea and creatinine are normal then there is no harm In doing contrast MRI. Take opinion from urologist before going for contrast MRI with serum urea and creatinine report.
