I am female am bleeding and clotting from my right kidney have had all tests including a biopsy and renal angiogram. Bleeding started 6 months ago with no relief just kept getting worse no pain at first but having kidney pain sporatic and sometimes burning in bladder while trying to pass urine with a blood clot . No stones or cancer from tests that have been taken. Cystiscopes show only right kidney involved. Had biopsy on area not receiving blood (shows as dark spot) negative for cancer but tested as cronic infection. Took antibiotics for three weeks but condition just increased. I am really concerned that the doctor has not found the cause yet and doesn t seem concerned about the continued symptoms and their increase? What should I do? She is planning a procedure that will go through the bladder to the kidney to hopefully find a cause that can be corrected at that time and insert a stint that will be removed in office at a later date. I am 68 and had several kidney infections in my early years. Had a kidney lift in my 20 s where they reattached the affected kidney that had fallen and was creating serious pain and urine backup. Since that surgery I have been healthy until Dec 2013 to the present. Any input would be helpful.
