title: The effect of short-term high-dose treatment with methenamine hippurate of urinary infection in geriatric patients with indwelling catheters. I. The preparation and morphology of a quantified urine sediment.
abstract: A quantified sediment of the urine from patients with indwelling catheters was prepared by fixation of 0.1 ml urine in 0.9 ml 2% glutaraldehyde immediately after sampling. Slide preparations were then made from 0.2 ml of the glutaraldehyde suspensions by means of a cytocentrifuge. Bacteria and epithelial cells were properly contrasted by the May-Grünwald-Giemsa stain but haematoxylin-eosin and the Papanicolaou stain were superior as regards leukocyte morphology. It is suggested that glutaraldehyde-cytocentrifuge preparations of the urine cytology may be useful in the evaluation of urinary infection and in the evaluation of the therapy of urinary infection.
