Comparative examinations of different renal biopsy techniques in dogs.

摘要

The purpose of the experiment was to compare renal biopsy techniques for dogs as well as to evaluate the usefulness of manual needles in comparison to automatic needles. Renal biopsy was performed on a group of 25 mixed-breed dogs of both sexes, aged 6 to 14 years, divided into four groups. On group I (5 dogs), percutaneous biopsy was performed using Tru-cut manual needles with the aid of kidney localisation by palpation in the area of paralumbar fossa. On group II (5 dogs), percutaneous biopsy was performed using Monopty automatic needles. On group III (10 dogs) a "keyhole" technique was performed using Monopty automatic needles. Laparoscopy-guided biopsy of the kidney was performed using Monopty automatic needles on group IV (5 dogs). Considering factors such as the quality of biopsy specimen, precision, grade of safety and operator's comfort, the study has demonstrated that the best results were obtained with the use of the laparoscopy-guided technique in connection with Monopty automatic needle.
