EFFECT OF SHORT-TERM HIGH-DOSE TREATMENT WITH METHENAMINE HIPPURATE OF URINARY-INFECTION IN GERIATRIC-PATIENTS WITH INDWELLING CATHETERS .1. PREPARATION AND MORPHOLOGY OF A QUANTIFIED URINE SEDIMENT

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 suspension by a cytocentrifuge. Bacteria and epithelial cells were properly contrasted by the May-Gruenwald-Giemsa stain but hematoxylin-eosin and the Papanicolaou stain were superior as regards leukocyte morphology. 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.
