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.
