[Elaboration of organ-sparing operations in cavernous tuberculosis of the kidneys].

A clinico-experimental study was performed in 132 rabbits and 8 patients. The formation of so-called "giant caverns" is thought by the authors to be due to disturbed vascularization of proximal portions of the tubules resulting in their gradual destruction and fusion. The necessary removal of not only the superficial retention structures erroneously called "giant cavern" but also the somewhat deeper caseous-cavernous tuberculosis focus is stressed.
