Our objective in this next phase, was to test the validity of this new partial nephrectomy bench model. METHODS A questionnaire evaluating face and content validity was distributed to urology staff, fellows and residents at a single institute. The questionnaire assessed the utility of the model as a surgical education tool using a 5-point scale. It asked participants to score the anatomical representation of the kidney model and the cutting, suturing, knot-tying and tissue tearing characteristics compared to a human kidney. Participants' opinion of the model's value as a training tool was also assessed. Participant level of training and clinical experience in performing laparoscopic and open surgery were collected. RESULTS Twenty participants assessed the model and completed the questionnaire (8 staff, 4 fellows, 5 senior residents and 3 junior residents). Eighteen participants (90%) agreed or strongly agreed that the model was a good representation of a human kidney and tumor and two (10%) participants were neutral in opinion. Sixteen participants (80%) agreed or strongly agreed that cutting through the model was similar to that of human kidney tissue, two (10%) were neutral and two (10%) disagreed in opinion. The median suturing score (out of 5) on the model were as follows: needle insertion=4, needle driving=3.5, knot/tying=4 and tissue tear strength=4. Overall, 19 participants (95%) agreed or strongly agreed that the model would help in laparoscopic training and 15 (75%) agreed or strongly agreed it would help in open surgical training. All participants would recommend use this model for resident training. We compared the responses of residents versus staff for all the above parameters and found no statistically significant difference (p>0.05). CONCLUSIONS Our partial nephrectomy model engineered using actual measures of tear strength and resistance of a real kidney demonstrates good face and content validity. Both experts and novice felt that this model was realistic and had potential educational utility. Validation of training utilizing this model will be the next step in our research. © 2012 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 187Issue 4SApril 2012Page: e608 Peer Review Report Advertisement Copyright & Permissions© 2012 by American Urological Association Education and Research, Inc.MetricsAuthor Information Abdulaziz Alamri Hamilton, Canada More articles by this author Alym Abdulla Hamilton, Canada More articles by this author John Madjeruh Hamilton, Canada More articles by this author Edward D.
