Abstract: Percutaneous needle biopsy of the kidney may be helpful in formulating prognoses and treatment plans for some disease of kidney. Ultrasound guidance for renal biopsy improves the efficacy of the procedure. Complications of renal biopsy include hematuria, hemorrhage, infection, local peritonitis and severe circulatory dysfunction. The purpose of this study was to evaluate the accuracy of the technique and the possible complications of biochemical, hematological, radiological, ultrasonographical and pathological changes after ultrasound-guided needle biopsy of the kidney. Ten adult dogs were used, an 18 gauge Vim Tru Cut biopsy needle was introduced into the cranial pole of the right kidney using sonographic guidance. Clinical, ultrasonography and radiology, hemathological, biochemical and pathological changes were evaluated after biopsy procedure. All the biopsy samples contained renal tissue. Clinical evaluations showed that changes were all within normal reference ranges. Ultrasonographically and radiologicallly evaluations showed that no changes in kidney sizes. The results of hematological and biochemical evaluations showed that no statistically significant difference (p>0.05) between blood samples performed pre-biopsy and post-biopsy was found during the study. The results of this study indicate that the ultrasound-guided renal biopsy can be safely obtained from healthy dogs using 18-gauge Vim Tru Cut biopsy needle. Our study suggests that ultrasound-guided renal needle biopsy procedure has a minimal complication in dogs.
