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.

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 directions

ABSTRACT: Since the introduction of nephron-sparing surgery, patients with small renal masses and diseases affecting overall renal function have greatly benefited.
We present the case of a 62-year-old male with a 6-cm left renal tumor in the medial parahilar segment with right renal unit functionally excluded, secondary to chronic obstruction due to ureteral lithiasis. Right ureteroscopy was performed with pneumatic lithotripsy. Despite localization and size of the tumor, left nephron-sparing surgery was performed in order to preserve renal function. Follow-up of the patient demonstrates no tumor activity.
Open nephron-sparing surgery has been the standard treatment for small renal masses with peripheral localization; however, in specific cases with deteriorated renal function and tumors >5 cm close to the renal hilum, certain risk must be taken in order to perform this procedure that has proven to be highly effective in preserving renal function. Open nephron-sparing surgery represents a highly effective procedure in small renal masses with a nonfunctional contralateral kidney.
