Hi, it was discovered I had hematuria at my routine gyn exam, and mild hypertension. Referred to my family dr who repeated and found microscopic and dipstix +. No gross hematuria noted. Sonogram showed bilateral cortical thinning of kidneys. Did cmp, sed rate, cbc, 24 hr urine for Protein and creatinine....all perfectly within normal limits, What is the renal cortical thinning from? Dr said it might be congenital? but wants to send me to urologist for cysto, but during this time, I was also diagnosed with breast ca and she wants me to have breast sx first? What do you think ?
