kidney tumor nephron-sparing operation

summary

Objective. In all more fre±uently performed nephron-sparing operations, in
patients with renal tumours while deciding about operational treatment, tumor
localization and its relation to the arterial yessels should be of major importance.
Material and methods. Precise kidney angioarchitecture knowledge allows
vessel-sparing incisions choice. Vessels and pelveo-calyceai system of 9 kidneys
were filled up with plastic mass. Specimens have been exposed to sodium alkali
reactions. Experimental renal parenchyma incisions have been performed and
then we analysed and described the number and size of cut arteries and the
reduction of renal tissue.
Results. Ischaemic effect of the sphenoid resection is the same as in the case
of the transversal resection of kidney parenchyma. Radial incisions near the
kidney hilus destroyed large part of kidney parenchyma. Longitudinal incisions
destroyed the higher number of the interlobar arteries than radial incisions.
Conclusions. Exact knowledge concerning intrarenal vascularity is usefull
in nephron-sparing surgery of renal tumors and allows to diminish intraopera-
tive bleeding and the area of ischaemic necrosis.
