hi all- looking for some help/advice/etc. my father (age 72) had a stem cell transplant for large B cell lymphoma on 10/10/06. over the course of the past week, his serum creatinine has been steadily bumping up every single day. he has great urine output, but the number continues to rise. unfortunately, he has low-grade temps and a kidney biopsy can't be done. anyone out there experienced anything similar? or just post-chemo serum creatinine increase? thanks...
