[|Human|] My mother in law had a kidney biopsy about 4 weeks ago and today she walked quite fast to catch a bus then had tummy ache and is now plowing a lot of blood from where u wee out of? Its not the first time this has happened she had it before the biopsy but it wasnt as hard as now
[|AI|]  Hi. Thanks for your query and an elucidated history. Noted the history of kidney biopsy, hematuria in past and now after 4 weeks after the kidney biopsy. The most probable cause looks to be your Mother in Law is having cancer of the kidney. I would advise urgent CT scan / MRI for the urogenital system to find the cause of bleeding, the extent of involvement of the tissues, the nature of spread of the cancer is this is so and to get an appropriate treatment. She may need an admission to the hospital and blood transfusion if the bleeding is severe.
