Impact of nephron sparing on kidney function and non-oncologic mortality
ABSTRACT The surgical management of kidney tumors has significantly evolved over the past decade. Partial nephrectomy and nephron sparing surgery have emerged as the treatments of choice for most newly diagnosed kidney tumors at tertiary care centers. The trend towards an organ sparing approach is largely due to an improved understanding of the global importance of kidney function as well as the impact that kidney surgery may have on non-oncologic morbidity and mortality. In addition to reviewing the methods of evaluating kidney function, this article discusses the effectiveness of various nephron sparing techniques in preserving kidney function and improving non-oncologic outcomes.

Conference Paper: Limit surface and moment function descriptions of planar sliding[Show abstract] [Hide abstract]
ABSTRACT: The authors present two geometric descriptions of the frictional properties of a rigid body sliding on a planar surface. The limit surface from classical plasticity theory, is the boundary of the set of all possible frictional forces and moments that can be sustained by the frictional interface. Zhukovskii's moment function is the frictional moment as a function of the instantaneous center of rotation's location. Both of these descriptions implicitly contain the full relationship between slip motion and frictional load for an object that makes contact governed by a useful class of friction laws that includes Coulomb friction. These surfaces can be used to deduce results concerning the overall frictional motion behavior of rigid bodies, such as the existence of characteristic final slip motion directionsRobotics and Automation, 1989.

ABSTRACT: The majority of kidney cancer tumors are small renal masses (SRMs). Partial nephrectomy is now established as the preferred treatment modality. In some patients the potential morbidity may outweigh the oncologic risk. Based on active surveillance studies, restriction of radical therapy to patients with aggressive tumors has been proposed. This has spurred renewed interest in development of radiologic and biopsy-based diagnostic techniques that can identify high-risk disease. This article discusses the natural history and pathologic features of SRMs, the evolving role of biopsy, and provides an overview of outcomes of various treatment approaches and current recommendations for management.Hematology/oncology clinics of North America 08/2011; 25(4):717-36.
