An update on aspects and use of different experimental models applied in kidney transplant research is presented . This paper includes qualities, as long as similarities between most frequently used animal models and human clinical standards. Contributions of those models based on microsurgical or laparoscopic techniques are revised. The physiological consequences (hemodynamic, immunologic) of surgical technique (laparoscopy), applied in experimental models as long as non-heart beating organ donor models and organ preservation methods are also reviewed. Finally, an update of those models applied in research in prothocols of either immunosupression or xenotransplant is done.

ABSTRACT: To determine the current state of kidney transplantation (KT) training in a country that is leader in organ donation and transplantation. We conducted an online survey by e-mail to 138 urology residents. The survey contained 5 sections: affiliation, training in KT, interest in KT, residents of transplant centers and residents of nontransplant centers. Sixty-five residents responded, 47.1% of the urologists in training surveyed, representing 28 cities and 15 provinces. Fifty-five percent (n=36) of the respondents deemed the KT training offered during their residency as insufficient, and 85% (n=55) demanded more resources. More than half were not confident in their abilities to perform transplantation surgery over the course of their residency (n=35). Nineteen percent of the residents considered KT an important discipline in their residency, with a mean score of 56.2 (1-100). Among the residents of the transplant centers (69.2%, n=45), 73% (n=33) considered KT when choosing a center for their residency. Of the surveyed residents from nontransplant centers (30.7%, n=20), 45% (n=9) do not perform an external rotation in KT. The surveyed residents demand more training in KT. The most common situation is to end a residency without having performed a complete KT. KT is considered an asset when selecting a resident medical intern position and commonly they are part of the transplantation team. The majority of residents are trained in centers with less than 75 transplants/year. External rotations in KT are not the rule in centers where transplantation is not performed. Copyright © 2014 AEU.

ABSTRACT: To describe a novel cadaver-based model for practicing renal transplant (RT) surgery. A simulating model using cadavers preserved by Thiel's method is developed to teach surgical anatomy and operative skills in RT surgery. Participants were asked to complete a voluntary, anonymous survey evaluating perceptions of the model and comparing cadaver sessions to other types of learning (rating questions from 0-10). Large university teaching hospital. A total of 28 residents, junior transplant surgeons, and faculty members were participants in the cadaver simulation. Overall, 9 cadavers were used with 17 grafts transplanted. Kidney procurement in human cadavers preserved using Thiel's embalming technique was performed following the conventional protocol; en bloc nephrectomy with the trunk of aorta and inferior vena cava. Bench surgery was performed, perfusing artery with saline and checking vascular permeability. Once suitability is established, RT was performed as is done in clinical practice. This embalming method enables tissue dissection that is comparable to the living body and provides suitable conditions for realistic RT simulation; handling human tissues and vessels in the same surgical field as the clinical scenario. This experimental model approximates to in vivo RT, providing a realistic and interesting learning to inexperienced surgeons. Overall, participants held a positive view of the cadaver sessions, believed them to be useful in their daily practice, and felt that the proposed model was similar to the clinical setting. Trainees believed that these practices improved skills and confidence in performing an RT. The proposed method of kidney procurement and RT in human cadavers preserved by Thiel's embalming technique is a promising, realistic, and reproducible method of practicing RT surgery.
