[Experimental kidney preservation for 30 hours in Collins' solution: angiographical and isotope nephrographical findings after autotransplantation].

In experiment canine kidneys preserved in Collins' solution can be kept vital for 30 hours. Angiography after autotransplantation of these kidneys shows good circulation during the immediate postoperative period. Isotope nephrography reveals reversible damage of tubuli which disappears till the 28th day after operation. This procedure of preservation causes tubular damage but does not impair the parenchymatous blood supply. Tubular regeneration therefore is possible.
