title: [Comparison of 2 methods of diagnosis of changes in transplanted kidneys in the early postoperative period: biopsy vs dynamic scintigraphy of the graft].
abstract: Renal transplantation is at present a standard therapeutic method in chronic renal insufficiency. For a favourable development of the graft some investigated criteria are of basic importance: basic diagnosis which led to renal failure, period of dialyzation treatment, high standard collection and perfusion and early diagnosis of the rejection episode. Non-invasive diagnostic methods of the rejection episode are always indirect and correlate with histologically confirmed rejection, depending on the period of transplantation in 10-90% patients. Indirect diagnosis is based in particular on a rise of the creatinemia, decline of glomerular filtration, fluid retention variations of blood pressure and increase of the Doppler assessed index of resistance (IR) in the peripheral veins of the graft [1]. For many years the role of nuclear diagnostics are tested. The disadvantage of direct diagnosis--biopsy--is increased haemorrhage and loss of the graft [1, 2, 3, 4]. The greatest problem is the differentiation of acute (cellular) rejection as compared with acute tubular necrosis during the initial days after transplantation. The authors describe their experience with 81 biopsies in the course of 3 years in patients during the first 10 days after transplantation, comparison with dynamic scintigraphy of the graft. Their attention is focused on the technique and risks of renal biopsy.
