Abstract

Objective: To determine if a simulation lab using lightly embalmed cadavers would improve diagnostic medical sonography (DMS) students’ perceived competence in ultrasound-guided native renal biopsy examinations. Methods: Subjects included DMS students (n = 49) enrolled in academic years 2012 to 2018. Each DMS student performed a native renal biopsy with a nephrology fellow. Skills practiced included machine setup, inferior renal pole localization, biopsy guide preparation, needle visualization, and communication skills. Pre- and postlab surveys assessed DMS students’ perceived competence. Results: Prelab, 12% (n = 6) of students felt competent to assist in the procedure. Postlab, 61% (n = 35) of students felt competent, a statistically significant (P <.001) change. All students viewed the lab as a valuable experience. Hands-on experience (53%), student/physician collaboration (33%), and low-stress environment (13%) were reported themes. Additional resources (50%) and scheduling (22%) were areas for improvement. Conclusion: A renal biopsy simulation lab using lightly embalmed cadavers is an effective method to improve DMS students’ perceived competence in this procedure.
