Renal biopsy in the normal cat: an examination of the effects of a single needle biopsy.
Eleven healthy cats were subjected to a single, percutaneous renal biopsy with a disposable biopsy needle and thereafter monitored clinically and by means of laboratory analyses of blood and urine until euthanasia at intervals up to two months after biopsy. Biopsy specimens were obtained at each attempt and the specimen length and numbers of glomeruli compared favourably with results from normal dogs biopsied with Franklin-Silverman needles. At necropsy radiographic studies demonstrated renal vascular changes and histological examinations of the biopsied kidneys revealed lesions varying from barely discernible linear scars to extensive haemorrhage and wedge-shaped infarcts. A direct relationship was established between the severe renal lesions in seven cats and biopsy specimens containing medullary tissue and major renal blood vessels.
