Background & aims : Kidneys are the main excretory organs in our body. About one-fifth of the total cardiac output is supplied to the kidneys via renal arteries. This study focusses on renal artery branching pattern which is very useful for various surgical procedures. This study is done by taking a cast of vascular segments of kidney by injecting a silicone rubber into the renal arteries using RTV 116 silicone rubber. Materials and metbods : Kidney specimens from well embalmed cadavers were taken and a flowable silicone rubber is injected into the renal arteries via a cannula. Then the arteries were ligated and kept aside to solidify. Next step was to bring about degradation of the kidney tissue to leave behind the silicone rubber residue of the branching pattern by immersing the organ in KOH solution. Result: Branching pattern was observed and documented in all 20 specimens. Conclusion: Knowledge of the branching pattern of renal artery is instrumental in surgeries for it to be a success and more so in renal transplants. Thus, this study would help to provide a better picture of vascularization of the kidney along with its segmental pattern.
Background: Knowledge of anatomy, one of the core preclinical subjects, is very important for medical undergraduates to have a thorough understanding of various clinical conditions. The traditional method of learning anatomy involves dissection of human cadavers. Medical education system is entering an era in which the traditional teaching methods are being supplemented by newer technological teaching techniques. Simulation based teaching like virtual dissection table “Anatomage” can enhance the understanding and retaining capacity of the subject. The aim of the study is to determine the perception of virtual dissection, among students and staff and to compare the knowledge acquired through simulation based teaching and traditional teaching method. Material and Method: The study comprised of 150 first-year MBBS students who attended regular theory class on ‘joints of musculoskeletal system’ and answered pre-test. The students were divided into two groups, based on teaching method, one which involved the use of a virtual dissection table, and the other, involving the use of cadaveric dissection. The students were made to attempt the post-test. The students were then assessed based on their responses to the pre- and post-tests. Feedback on the overall utility of the table from both students and staff was taken. Results: The mean post-test scores were significantly higher than the mean pre-test scores, irrespective of the teaching method used. (p<0.001) However, the students who were exposed to the virtual dissection table scored comparatively better in the post-test than those exposed to cadaveric dissection. (p<0.001) 100% of the faculty and 93.3% of the students agreed that three-dimensional visualization improves understanding of anatomical structures. Conclusion: The findings of this study suggest that though cadaveric dissection and virtual dissection enhance learning, the students tend to perform better with virtual dissection. The incorporation of simulation-based teaching into the Anatomy curriculum is essential to supplement traditional cadaveric dissection and ensure engaging as well as high impact delivery of the curriculum.
