I had surgery November 20 for squamous cell carcinoma on my right cheek. Two weeks ago, it became infected and found a small hairlike substance  in the wound and was treated with Keflex. Today, found wound infected again and went to the doctor. They cultured wound, guessing now is MRSA, and gave me Antibiotics. Now, found letter in mail saying my doctor wants new labs as my kidney function showed concern. This is the second time post surgery, my kidneys showed something high (I forgot what) after surgery. I am 48. I am an athlete and health care professional. You may speak in medical terms. Thank you.
Hello and welcome to Chat Doctor, The squamous cell carcinoma is not directly related to the kidney function tests. Kidney diseases do not show up early in the course of disease because the kidney compensates it. The normal kidney takes over the functions of diseased kidney tissue. The renal function tests turn abnormal only when the disease becomes advanced. You have mentioned that you acquired wound infection for which you took some antibiotic. There are some groups of antibiotics which affect the renal functions. The compromise seen in renal functions could be due to these antibiotics. You need to consult your doctor for management of the compromised renal functions. Thanks and take care Chat Doctor.
