Use of artisanal simulators in the ultrasound training for invasive procedures in nephrology: venous access and renal biopsy

INTRODUCTION: Vascular access and renal biopsy are common procedures in nephrology. In this study, two artisanal simulators of very low cost and excelent image quality are (prented) presented to guide, by ultrasound, the venous access and renal biopsy. METHODS: The simulators are constructed using chicken breast slices, Penrose drain, plastic milk shake straw and pig kidney. RESULTS: Both simulators enable immediate identification of the anatomical structures of interest, vessels and kidney, and enable spatial orientation and hand-eye coordination, essential for the development of the necessary skills to safely carry out invasive procedures. CONCLUSION: The simulators described, were extremely useful for simulating venous access and renal biopsy guided by ultrasonography, enabling training to reduce the failure rate in punctures and the potential complications associated with the described procedures.
