Plain-English summary
Ten healthy cats underwent a new kidney biopsy technique that involved immobilizing the kidney for better sample collection. After the procedure, some cats showed a temporary drop in red blood cell levels, blood in the urine, and minor bleeding around the kidney, but these issues resolved within 48 hours without any serious complications. The biopsies were successful, with 95% of the samples containing kidney tissue and all samples being of good quality for diagnosis. This method appears to be safe and effective for obtaining kidney tissue in cats.

Abstract
PURPOSE: Evaluate a new immobilization kidney method for collecting blind percutaneous renal biopsies (RB) in healthy cats. METHODS: Ten cats were biopsied by a modified blinded percutaneous technique using semi-automated needles. Were evaluated the operational aspects of the technique, its complications, and the quality of the obtained samples. The evaluation included physical examination, hemogram, urinalysis, abdominal ultrasound, renal function, and histopathology of the biopsy specimens. RESULTS: The developed technique was fast and easy to perform; it required two operators, and the right kidney was elected for specimen collection. After the RB, a decrease in hematocrit levels was observed in addition to hematuria and perirenal transient hematoma; however, no clinical consequences were observed, and normal parameters were restored within 48 hrs. There were no major complications or deaths, alterations in the physical examination or renal function, or signs of infection. Of the samples, 95% revealed the presence of renal tissue, and in 100% of the cats the samples were of diagnostic quality. CONCLUSION: The technique was easily performed, provided adequate material for diagnosis with minimal transient complications.
