[Possibility of renal vascularization by means of a jejunal flap]

An animal experimental model for the additional vascularisation of the kidney is represented by means of an excluded demucosed small intestine segment. The immediate clinical signification is to be seen in lowering the hypertension in case of pyelonephritic renal shrinkage. Histologic investigations do not show any vascular communication between intestine and kidney and not any ingrowing of intestinal vessels in the kidney. If the improvement of reno-intestinal shunts could be particularly stimulated in case of a primary restricted blood offer must remain unsolved.
