[Spontaneous ruptures of allotransplants of human cadaveric kidneys]

On the basis of morphological data it was established that spontaneous ruptures of allotransplanted kidneys of man were connected mainly with juxtamedullar shunting of their blood flow; Impairment of the blood flow was apparently caused both by immune and nonimmune endogenous humoral factors. The pathomorphological picture in spontaneous ruptures of transplants differed from structural changes observed in traumatic damage of the kidney.
