The standard therapy of kidney tumors is partial or total resection of the kidney depending on the tumor size and place, among other factors. Both are considered major surgeries. To decrease the side effects and complications of these surgeries, laparoscopy is now used. In cases of partial nephrectomy - removing only part of the kidney which harbors the tumor- the blood vessels of the kidney should be closed up temporarily to control bleeding. Nevertheless, bleeding can occur alongside the adverse effect of that vessel closure on the kidney function. The advantage of laser resection of this tumor is clear enough here as it is done through the laparoscope, avoiding open surgery, closure of the kidney vessels, and bleeding.
