 Thank you very much for that opportunity to present. I just have a case presentation that will hopefully highlight the issues for our session here. It's actually one of the first patients I saw. So this is a four-year female who came to see me for grocery material and left-flank pain. She had previously been seen in the ER after she passed a small left renal calculus. Her past model is notable for hypertension, some moderate obesity, and her surgical history is listed there. In the physical exam, essentially as a benign exam, she's mildly obese. Her urine cytology was negative. She had normal hemoglobin. Her sermon creatinines 0.8, her liver function tests were normal. And given the renal mass, I'm about to show you her CT, the chest was negative. So here are some representative images of the CT scan. She had an approximately 7 to 8 centimeter left upper pole renal mass. There was no associated lymph adenopathy. So in summary, this is a four-year female who I saw for a localized left renal mass, 8, 7, 8 centimeters in size. It was considering for renal cell carcinoma. Some of the treatment options were partial frectomy, arachnal frectomy, and arachnal frectomy with recuperative lymph node dissection, given her young age. She really wanted minimally invasive surgery. She underwent a laparoscopic left arachnal frectomy in September of 2013. She discharged home on post-up day two. Her histology actually was quite aggressive as clear cell renal cell carcinoma from in grade four, 8 centimeters in size. There were four lymph nodes in the hyalum that were all negative. It extended to renal sinus fat and perinephric fat. She has a T3A N0 renal cell carcinoma. Her scimocrani at return bit was 0.9. Thank you.
