Have 9 mm cortical thickness of left kidney, occasional flank pain on both sides, blood clots in urine, sudden absence of menstruation since blood in urine/blood clots began, but no kidney stones. Ultrasound in January was unremarkable. However, Ive had the above listed symptoms frequently in past three months. Could this be a sign of renal failure?
Hi, Welcome to Chat Doctor forum.  The symptoms have nothing to do with the kidney failure, there will be the moon face edema of the face, generalized body swelling, Núria are usually seen.  Clots in the urine may be due to the problem with the bladder, and cortical swelling may be due to the HY Chat Doctor.  Absence of the periods may be due to the anemia, or pre menopause.  I advise you to consult a urologist for diagnosis and treatment.  Wishing for a quick and complete recovery. Thank you.
