摘要

The authors of the preceding article report on a retrospective series of percutaneous nephrolithotomy procedures spanning a 7-year timeframe, and they divided the patients into groups on the basis of whether they underwent general (GA) or spinal (SA) anesthesia. Their conclusions importantly suggest a decreased bleeding and transfusion risk with SA vs GA, which the authors suggest might be because of a decreased central venous pressure that results from the peripheral vasodilation associated with SA.
