An hour before nephrectomy 10 patients with hypernephroma and 2 with pyonephrosis underwent occlusion of the renal arteries with gelfoam via selective catheterization, using the Seldinger percutaneous technique. This technique facilitated the operation by collapsing the renal and perirenal veins, decreased blood loss and prevented the dissemination of tumor cells or septic emboli from organ manipulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
