Analysis of urine sediments after kidney transplantation.
We applied multiparameter flow cytometry for the first time to the classification of cells and particles of urine sediments after kidney transplantation. After fluorescent staining with acridine orange, cells and particles were checked for their size and their peak intensity of green and red fluorescences, known to be related to the amounts of intracellular DNA and intracellular RNA, respectively. Urine sediments were tested daily during a period of up to three weeks. Occurrence and disappearance of certain classes of cells and particles were found to be similar among different patients during normal healing. The results from patients without rejection of the graft are suggested as baseline data, differences from which should be detectable with high sensitivity due to the large number of cells being examined.
