LAPAROSCOPIC RADICAL NEPHRECTOMY Urology Clinic GW Medical Faculty Associates The George Washington University 2150 Pennsylvania Avenue, NW Washington, DC 20037 PURPOSE Laparoscopic Radical Nephrectomy is a minimally invasive technique to remove the entire kidney and surrounding fat that is usually used as a treatment for primary renal tumors. GENERAL INFORMATION Radical nephrectomy or removal of the entire kidney and surrounding fat was traditionally the treatment of choice for most solid renal tumors.
The VQ scan does not hurt. You will feel a prick when the liquid is injected. How long will the test take? A VQ scan will take about 1 hour to complete. A VQ scan is a nuclear medicine exam performed to evaluate the airflow and blood flow in the lungs. The airflow is evaluated by breathing in an oxygen mixture containing a radioactive tracer that a special camera can detect.
VQ Ratio can therefore be defined as: the ratio of the amount of air reaching the alveoli to the amount of blood reaching the alveoli. These two variables, V & Q, constitute the main determinants of the blood oxygen (O2) and carbon dioxide (CO2) concentration. The V/Q ratio can be measured with a ventilation/perfusion scan. A V/Q mismatch can cause a type 1 respiratory failure.
