Abstract
BACKGROUND The safety of laparoscopic donor nephrectomy (LDN) has been widely documented, but its challenging learning curve (LC) requires an insightful assessment to expand its application. The aim of this study was to evaluate LC of LDN in a high-volume transplant center. METHODS Three hundred forty-three LDNs performed from 2001 to 2018 were evaluated. CUSUM analysis based on the operative time was used to assess the number of cases required to reach mastery in the technique for both the entire surgical team and for the 3 main surgeons considered separately. Analysis of association between demographics, perioperative characteristics, and complications within the different LC phases was conducted. RESULTS Mean operative time was 228.9 minutes. Mean length of stay was 3.8 days and mean warm ischemia time (WIT) was 170.8 seconds. Surgical and medical complication rates were 7.3% and 6.4%, respectively. The CUSUM-LC showed a requirement of 157 cases (for surgical team) and 75 cases (for single surgeons) to reach competence in the procedure. Patient baseline characteristic showed no differences among the LC phases. Compared with the initial LC phase, hospital stay was significantly lower at the end of the LC whereas WIT results were longer in the LC descendent phase. CONCLUSIONS This study confirms the safety and efficacy of LDN, with a low rate of complications. This analysis suggests that about 75 procedures are required to reach competence and 93 cases to achieve mastery level of skill for a single surgeon. It can be hypothesized that, in a high-volume transplant enter, the time to guarantee training in LDN is compatible with the duration of a clinical fellowship.

Abstract
BACKGROUND The surgical learning curve is an observable and measurable phenomenon. Operative experience targets are well established as a proxy measure for operative competence in surgical training across jurisdictions. The aim of this study was to critique the available evidence regarding the relationship between operative experience in surgical training and trainee competence. METHODS A systematic review of the PubMed, Embase, Web of Science, and Cochrane library databases was conducted in accordance with the Preferred Items for Systematic Reviews and Meta-Analyses guidelines. Articles were sought that defined the relationship between procedural volume in surgical training and trainee competence, proficiency, or mastery. The educational impact of included studies was evaluated using a modified Kirkpatrick model. RESULTS Of 3,672 records identified on database searching, 30 papers were ultimately included. Fourteen studies defined operative experience thresholds using operative time as a surrogate measure of competence, whereas another 8 used trainer assessments of operative performance (Kirkpatrick level 3). A further 5 studies were able to determine the relationship between trainee case volumes and subsequent patient outcomes (Kirkpatrick level 4b). CONCLUSION Many studies have recorded competent trainee performance in key index procedures after reaching experience threshold numbers in excess of currently mandated targets across jurisdictions. The evidence relating current operative experience targets to patient outcomes across a range of surgical subspecialties of surgical subspecialties is lacking. This review supports a move toward criterion-based referencing of operative performance targets in surgical training.

Abstract
BACKGROUND Little is known about the outcome of living-donor kidney transplantation (LDKT) performed in low-volume centers lacking the services of full-time transplant surgeons. This retrospective cohort study assessed the outcome of LDKT performed in a low-volume center by visiting transplant surgeons from a high-volume center and managed perioperatively by transplant nephrologists. METHODS We compared Japanese adult patients who had no donor-specific antibodies and underwent LDKT between 2006 and 2015 either in a low-volume (n = 31) or high-volume (n = 481) center. In the low-volume center, visiting transplant surgeons from the high-volume center conducted LDKT and transplant nephrologists managed the recipients peri- and postoperatively. The primary outcome was the composite of infection, cardiovascular disease, or cancer during 1-year follow-up. The outcomes of the low- and high-volume centers were compared using 1:2 propensity score matching. RESULTS After matching, 9 of 29 patients in the low-volume center (31.0%) and 16 of 58 patients in the high-volume center (27.6%) experienced the primary composite outcome (risk ratio = 1.13; 95% confidence interval, 0.57-2.23). There were no significant differences between the 2 groups in graft function at 1 year, all-cause graft loss, biopsy-proven rejection, and urological complications. However, the median duration of post-LDKT hospitalization was significantly longer in the low-volume center than in the high-volume center (23 and 16 days, respectively). CONCLUSIONS Among Japanese patients without preformed donor-specific antibodies, LDKT conducted at a low-volume center by visiting transplant surgeons from a high-volume center and managed clinically by transplant nephrologists was not associated with significantly higher risk of postoperative complications.

Abstract
The introduction of laparoscopic donor nephrectomy caused a shift toward' left donor nephrectomy. Some centers report a significantly low rate of endoscopic right donor nephrectomy. Hand-assisted retroperitoneoscopic donor nephrectomy (HARP-DN) was introduced as a novel surgical technique, which aims to avoid intra-abdominal complications. It was also reported to provide technical advantages for right-sided DN. In this retrospective single-center study, we evaluated the impact of HARP-DN technique on utilization of right-sided DNs. After the implementation of HARP-DN on February 2009, a total of 565 DNs were performed until December 2015. The introduction of HARP-DN technique resulted in an immediate increase in the utilization of right kidneys from 6.1% to an average of 19.6% annually. The donors 'outcome was similar to the left-sided and right-sided DN groups, excluding the increased incidence of incisional hernias in left kidney donors. None of the donors developed intra-abdominal complications. In conclusion, the implementation of HARP technique significantly increased the use of right-sided DNs, which enables a more liberal use of donors in LDKT.

Abstract
Objective: To evaluate if “state-of-the-art” 3D- versus 4K-display techniques could influence surgical performance. Background: High quality minimally invasive surgery is challenging. Therefore excellent vision is crucial. 3D display technique (3D) and 2D-4K technique (4K) are designed to facilitate surgical performance, either due to spatial resolution (3D) or due to very high resolution (4K). Methods: In randomized cross-over trial the surgical performance of medical students (MS), non-board certified surgeons (NBC), and board certified surgeons (BC) was compared using 3D versus 4K display technique at a minimally invasive training Parkour. Results: One hundred twenty-eight participants were included (February 2018 through October 2019, 49 MS, 39 NBC, 40 BC). The overall Parkour time (s) 3D versus 4K was 712.5 s ± 17.5 s versus 999.5 s ± 25.1 s (P < 0.001) for all levels of experience. It was (3D vs 4K) for MS (30 tasks) 555.4 s ± 28.9 s versus 858.7 s ± 41.6 s, (P < 0.0001), for NBC (42 tasks) 935.9 s ± 31.5 s versus 1274.1 s ± 45.1 s (P =< 0.001) and for BC (42 task) 646.3 s ± 30.9 s versus 865.7 s ± 43.7 s (P < 0.001). The overall number of mistakes was (3D vs 4K) 10.0 ± 0.5 versus 13.3 ± 0.7 (P < 0.001), for MS 8.9 ± 0.9 versus 13.1 ± 1.1 (P < 0.001), for NBC 12.45 ± 1.0 versus 16.7 ± 1.2 (P < 0.001) and for BC 8.8 ± 1.0 versus 10.0 ± 1.2 (P = 0.18). MS, BC, and NBC showed shorter performance time in 100% of the task with 3D (significantly in 6/7 tasks). For number of mistakes the effect was less pronounced for more experienced surgeons. The National Aeronautics and Space Administration-task load index was lower with 3D. Conclusion: 3D laparoscopic display technique optimizes surgical performance compared to the 4K technique. Surgeons benefit from the improved visualization regardless of their individual surgical expertise.

Abstract
Background Both laparoscopic surgery and computer games make similar demands on eye-hand coordination and visuospatial cognitive ability. A possible connection between both areas could be used for the recruitment and training of future surgery residents. Aim The goal of this study was to investigate whether gaming skills are associated with better laparoscopic performance in medical students. Methods 135 medical students (55 males, 80 females) participated in an experimental study. Students completed three laparoscopic tasks (rope pass, paper cut, and peg transfer) and played two custom-designed video games (2D and 3D game) that had been previously validated in a group of casual and professional gamers. Results There was a small significant correlation between performance on the rope pass task and the 3D game, Kendall’s τ(111) = -.151, P = .019. There was also a small significant correlation between the paper cut task and points in the 2D game, Kendall’s τ(102) = -.180, P = .008. Overall laparoscopic performance was also significantly correlated with both the 3D game, Kendall’s τ(112) = -.134, P = .036, and points in the 2D game, Kendall’s τ(113) = -.163, P = .011. However, there was no significant correlation between the peg transfer task and both games (2D and 3D game), P = n.s.. Conclusion This study provides further evidence that gaming skills may be an advantage when learning laparoscopic surgery.

Abstract
OBJECTIVE Living kidney donation is a unique operation, as healthy patients are placed at risks inherent with major surgery without physical benefit. The ethical implications associated with any morbidity make it a high-stakes procedure. Fellowships are faced with the dilemma of optimizing fellow training in this demanding procedure while providing safe outcomes to donors. The Laparoscopic Living Donor Nephrectomy (LDN) Workshop is a resource that can provide intense instruction to help bridge the training deficit. Our aim was to examine the course's effectiveness in improving fellows' skill and confidence related to implementing LDN into future practice. METHODS From 2017 to 2018, 36 abdominal transplant surgery fellows participated in a 2-day workshop consisting of live surgery observation, cadaver lab, and didactic sessions. Surveys were completed precourse, postcourse, and at 3-month postcourse follow-up. RESULTS Preworkshop, 61% of participants reported less than 50% confidence in independent performance of LDN. Following workshop completion, 95% reported improved confidence. At 3-month follow-up, there was a 30% (p < 0.05) increase in median confidence level. Immediately following the course, 67% reported improved ability to analyze kidneys prior to donation, 74% changed the way donor candidates were evaluated, and 67% reported enhanced ability to risk stratify donors. Eighty-five percent felt it strengthened operative techniques with 70% implementing new diagnostic treatments and surgical strategies. Seventy percent of participants felt it improved their communication with colleagues and 67% had enhanced communication with patients. These trends were maintained at 3-month follow-up. CONCLUSION These results indicated that the LDN Workshop improves confidence and increases fellows' skillset in a high-stakes procedure. The LDN Workshop is a useful adjunct to fellowship training to optimize successful, efficient, and safe performance of a demanding procedure in a uniquely healthy donor population.

Abstract
Background Several difficulty grading systems have been developed as a useful tool for selecting patients and training surgeons in laparoscopic procedures. However, there is little information on predicting the difficulty of laparoscopic donor nephrectomy (LDN). The aim of this study was to develop a grading system to predict the difficulty of LDN. Methods Data of 1741 living donors, who underwent pure or hand-assisted LDN between 1994 and 2018 were analyzed. Multivariable analyses were performed to identify factors associated with prolonged operative time, defined as a difficulty index with 0 to 8. The difficulty of LDN was classified into three levels based on the difficulty index. Results Multivariable analyses identified that male (odds ratio [OR] 1.69, 95% CI 1.37–2.09, P < 0.001), BMI > 28 (OR 1.36, 95% CI 1.08–1.72, P = 0.009), pure LDN (OR 1.99, 95% CI 1.53–2.60, P < 0.001), multiple renal arteries (OR 2.38, 95% CI 1.83–3.10, P < 0.001) and multiple renal veins (OR 2.18, 95% CI 1.52–3.16, P < 0.001) were independent risk factors influencing prolonged operative time. The difficulty index based on these factors was calculated and categorized into three levels: low (0–2), intermediate (3–5), and high (6–8) difficulty. Operative time was significantly longer in the high difficulty group (225 min) than in the low (169 min, P < 0.001) and intermediate difficulty group (194 min, P < 0.001). The conversion rate was higher in the high difficulty group (4.4%) than in the low (2.1%, P = 0.04) and the intermediate difficulty group (3.0%, P = 0.27). No significant difference in major complications was found between the groups. Conclusion We developed a novel grading system with simple preoperative donor factors to predict the difficulty of LDN. This grading system may help surgeons in patient selection to advance their experiences and/or teach fellows from simple to difficult LDN.

Abstract
Background Robotic assisted nephrectomy for living donation (RANLD) is a rapid emerging surgical technique competing for supremacy with totally laparoscopic and laparoscopic hand assisted techniques. Opinions about the safety of specific techniques of vascular closure in minimally invasive living kidney donation are heterogeneous and may be different for laparoscopic and robotic assisted surgical techniques. Methods We retrospectively analyzed perioperative and short-term outcomes of our first (n=40) RANLD performed with the da Vinci Si surgical platform. Vascular closure of renal vessels was performed by either double clipping or a combination of clips and non-transfixing suture ligatures. Results RANLD almost quintupled in our center for the observed time period. A total of n=21 (52.5%) left and n=19 (47.5%) right kidneys were procured. Renal vessel sealing with two locking clips was performed in 18 cases (45%) Both, clips and non-transfixing ligatures were used in 22 cases (55%). Mean donor age was 53.075±11.68 years (range, 28–70). The average total operative time was 150.75±27.30 min. Right donor nephrectomy (139±22 min) was performed significantly faster than left (160.95±27.93 min, P=0.01). Warm ischemia time was similar for both vascular sealing techniques and did not differ between left and right nephrectomies. No conversion was necessary. Clavien-Dindo Grade ≤IIIb complications occurred in (n=5) 12.5%. Grade IV and V complications did not develop. In particular no hemorrhage occurred using multiple locking clips or suture ligatures for renal vascular closure. Mortality was 0%. Thirteen kidneys (32.5%) were transplanted across the AB0 barrier. Conclusions RANLD is an emerging minimally invasive surgical technique which facilitates excellent perioperative and short-term outcomes also when using multiple locking clips or suture ligatures for renal vascular closure.

Abstract
BACKGROUND Hand-assisted laparoscopic donor nephrectomy (HALDN) has rapidly become the best alternative to open nephrectomy for living kidney donation. As more centers continue to adopt the laparoscopic technique, the safety of the initial transplants must be ensured while ascending the learning curve (LC). This study looks to determine the safety of HALDN and to describe the results of the LC in our center. METHODS We conducted a retrospective review of 500 HALDNs performed in our center from July 2003 to July 2017. We analyzed demographic and perioperative characteristics and complications during the first postoperative month. We divided HALDNs into 2 groups: before and after completing the LC (50 nephrectomies). For each group, we assessed operating room time, estimated blood loss, length of stay, and complication and conversion rates. RESULTS A total of 500 HALDNs were performed in the study period. Of those, 454 were analyzed in the 2 groups. The median operating room time was 2 hours, length of stay was 2 days, and blood loss was 50 cc. The overall rate of complication was 6.8%. There were significant differences between the 2 groups in operating time, blood loss, and length of stay (P < .05). No differences were found in terms of complication (P = .42) and conversion (P = .28) rates. CONCLUSION There was a significant decrease in operating time, blood loss, and length of stay in patients who underwent laparoscopic donor nephrectomy by an experienced laparoscopist. However, no differences were found in complication and conversion rates, which suggests that improvement in surgical training can be accomplished without altering the donor safety.

Abstract
OBJECTIVES Despite the present use ofthe laparoscopic technique for living-donor kidney nephrectomy, a search for alternative techniques continues.The aim of this study was to compare finger-assisted open donor nephrectomy versus laparoscopic donor nephrectomy. MATERIALS AND METHODS This study included retrospective data of 95 consecutive donors in a transplant center who were under going donor nephrectomy RESULTS: Donor demographics and clinical characteristics were generally similar between treatment groups. There were fewer female donors in the finger-assisted open donor nephrectomy treatment group (70.5% vs 29.5%; P = .003), but median body mass index was similar between groups (28 vs 26 kg/m²; P = .032). Patients who received laparoscopic donor nephrectomy had longer operative duration (3.5 vs 1.2 h; P < .001), longer combined length of incision (6 vs 5 cm; P = .001), andshorter median hospital length of stay (3 vs 4 days; P < .001). A left nephrectomy was preferred in both groups. Minor postoperative complications occurred less often in the finger-assisted open donor nephrectomy group (14.7% vs 31.6%; P = .0094). Donors who received laparoscopic nephrectomy had lower glomerular filtration rate at 1 year after donation (60 vs 89 mL/min/1.73 m²; P < .001) than donors who received finger-assisted nephrectomy. However, recipients of donors of both procedures had similar glomerular filtration rate at 1 year after transplant (65 vs 69 mL/min/1.73 m²; P = .5). CONCLUSIONS Our study demonstrated that finger-assisted open donor nephrectomy is a successful and safe alternative versus laparoscopic donor nephrectomy, providing favorable results for patients in terms of complications and outcomes.

Abstract
INTRODUCTION A major goal in living donor kidney transplantation is to reduce the physical burden for the donor. Key-hole surgery for donor nephrectomy is a safe procedure, but concerns regarding donor safety during the learning phase might be the reason for surgeons' reluctance to change to a minimal invasive approach. MATERIAL AND METHODS We analyzed the first 100 retroperitoneoscopic donor nephrectomies (RPDN) performed at our institution and compared the results to the last 50 mini incision donor nephrectomies (MIDN) regarding donor and recipient outcome, and analyzed the learning curves of RPDN. RESULTS The learning phase of RPDN was very short with significantly shorter operative times compared to MIDN (118 vs. 175 min, p < 0.001) and significantly fewer surgical complications (p = 0.03). RPDN patients rated the physical burden (p = 0.01) as lower, and they felt less bothered by the surgical scar (p = 0.03). CONCLUSION Introducing RPDN is safe, even during the learning phase of the surgeons. Changing surgical technique from MIDN to RPDN reduces the surgical burden of the procedure. Our study might encourage more transplant centres to adopt a minimally invasive approach.

Abstract
BACKGROUND While living kidney donation is considered safe in healthy individuals, perioperative complications can occur due to several factors. OBJECTIVE We explored associations between the incidence of perioperative complications and donor characteristics, surgical technique, and surgeon's experience in a large contemporary cohort of living kidney donors. DESIGN Living kidney donors enrolled prospectively in a multicenter cohort study with some data collected retrospectively after enrollment was complete (eg, surgeon characteristics). SETTING Living kidney donor centers in Canada (n = 12) and Australia (n = 5). PATIENTS Living kidney donors who donated between 2004 and 2014 and the surgeons who performed the living kidney donor nephrectomies. MEASUREMENTS Operative and hospital discharge medical notes were collected prospectively, with data on perioperative (intraoperative and postoperative) information abstracted from notes after enrollment was complete. Complications were graded using the Clavien-Dindo system and further classified into minor and major. In 2016, surgeons who performed the nephrectomies were invited to fill an online survey on their training and experience. METHODS Multivariable logistic regression models with generalized estimating equations were used to compare perioperative complication rates between different groups of donors. The effect of surgeon characteristics on the complication rate was explored using a similar approach. Poisson regression was used to test rates of overall perioperative complications between high- and low-volume centers. RESULTS Of the 1421 living kidney donor candidates, 1042 individuals proceeded with donation, where 134 (13% [95% confidence interval (CI): 11%-15%]) experienced 142 perioperative complications (55 intraoperative; 87 postoperative). The most common intraoperative complication was organ injury and the most common postoperative complication was ileus. No donors died in the perioperative period. Most complications were minor (90% of 142 complications [95% CI: 86%-96%]); however, 12 donors (1% of 1042 [95% CI: 1%-2%]) experienced a major complication. No statistically significant differences were observed between donor groups and the rate of complications. A total of 43 of 48 eligible surgeons (90%) completed the online survey. Perioperative complication rates did not vary significantly by surgeon characteristics or by high- versus low-volume centers. LIMITATIONS Operative and discharge reporting is not standardized and varies among surgeons. It is possible that some complications were missed. The online survey for surgeons was completed retrospectively, was based on self-report, and has not been validated. We had adequate statistical power only to detect large effects for factors associated with a higher risk of perioperative complications. CONCLUSIONS This study confirms the safety of living kidney donation as evidenced by the low rate of major perioperative complications. We did not identify any donor or surgeon characteristics associated with a higher risk of perioperative complications.

Abstract
Background Three-dimensional (3D) stereoscopic vision is crucial to perform any kind of manual task. The reduction from real life 3D to virtual two-dimensional (2D) sight is a major challenge in minimally invasive surgery (MIS). A 3D display technique has been shown to reduce operation time and mistakes and to improve the learning curve. Therefore, the use of a3D display technique seems to optimize surgical performance for novice and experienced surgeons. Inspired by consumer electronics, a 4K display technique was recently introduced to MIS. Due to its high resolution and zoom effect, surgeons should benefit from it. The aim of this study is to evaluate if “state-of-the-art” 3D- vs. 4K-display techniques could influence surgical performance. Methods A randomized, cross-over, single-institution, single-blinded trial is designed. It compares the primary outcome parameter “surgical performance”, represented by “performance time ”and “number of mistakes”, using a passive polarizing 3D and a 4K display system (two arms) to perform different tasks in a minimally invasive/laparoscopic training parkour. Secondary outcome parameters are the mental stress load (National Aeronautics and Space Administration (NASA) Task Load Index) and the learning curve. Unexperienced novices (medical students), non-board-certified, and board-certified abdominal surgeons participate in the trial (i.e., level of experience, 3 strata). The parkour consists of seven tasks (for novices, five tasks), which will be repeated three times. The 1st run of the parkour will be performed with the randomized display system, the 2nd run with the other one. After each run, the mental stress load is measured. After completion of the parkour, all participants are evaluated by an ophthalmologist for visual acuity and stereoscopic vision with five tests. Assuming a correlation of 0.5 between measurements per subject, a sample size of 36 per stratum is required to detect a standardized effect of 0.5 (including an additional 5% for a non-parametric approach) with a power of 80% at a two-sided type I error of 5%. Thus, altogether 108 subjects need to be enrolled. Discussion Complex surgical procedures are performed in a minimally invasive/laparoscopic technique. This study should provide some evidence to decide which display technique a surgeon could choose to optimize his performance. Trial registration ClinicalTrials.gov, NCT03445429.

Abstract
BACKGROUND An elevated body mass index (>30 kg/m2) has been a relative contraindication for living kidney donation; however, such donors have become more common. Given the association between obesity and development of diabetes, hypertension, and end-stage renal disease, there is concern about the long-term health of obese donors. METHODS Donor and recipient demographics, intraoperative parameters, complications, and short- and long-term outcomes were compared between contemporaneous donors-obese donors (body mass index ≥30 kg/m2) versus nonobese donors (body mass index <30 kg/m2). RESULTS Between the years 1975 and 2014, we performed 3,752 donor nephrectomies; 656 (17.5%) were obese donors. On univariate analysis, obese donors were more likely to be older (P < .01) and African American (P < .01) and were less likely to be a smoker at the time of donation (P = .01). Estimated glomerular filtration rate at donation was higher in obese donors (115 ± 36 mL/min/1.73m2) versus nonobese donors (97 ± 22 mL/min/1.73m2; P < .001). There was no difference between groups in intraoperative and postoperative complications; but intraoperative time was longer for obese donors (adjusted P < .001). Adjusted postoperative length of stay (LOS) was longer (adjusted P = .01), but after adjustment for donation year, incision type, age, sex, and race, there were no differences in short-term (<30 days) and long-term (>30 days) readmissions. Estimated glomerular filtration rate and rates of end-stage renal disease were not significantly different between donor groups >20 years after donation (P = .71). However, long-term development of diabetes mellitus (adjusted hazard ratio (HR) 3.14; P < .001) and hypertension (adjusted hazard ratio (HR) 1.75; P < .001) was greater among obese donors and both occurred earlier (diabetes mellitus: 12 vs 18 years postnephrectomy; hypertension: 11 vs 15 years). CONCLUSION Obese donors develop diabetes mellitus and hypertension more frequently and earlier than nonobese donors after donation, raising concerns about increased rates of end-stage renal disease.

Abstract
BACKGROUND Laparoscopic live donor nephrectomy has replaced open donor nephrectomy in most patients due to numerous benefits. A live animal model is required to equip surgeons with the necessary skills to perform such a procedure with minimal risk of complications. The aim of this study was to establish the technique for laparoscopic live donor nephrectomy in a porcine (Sus scrofa) model. MATERIALS AND METHODS This study was approved by the Animal Ethics Committee of the university. Forty-four pigs underwent laparoscopic live donor nephrectomy. The left kidney was removed with a standardized four-port technique, with a small suprapubic incision to facilitate kidney delivery. RESULTS All 44 procedures were performed successfully, with no intraoperative complications or conversion to open surgery. There was no apparent damage to any of the kidney grafts. The mean surgical time was 118.3 (±20.7) minutes. There was a small, but statistically insignificant, decrease in surgical time throughout the duration of the study. Several subjects had minor variations in the anatomy of the renal vasculature. CONCLUSIONS This series has developed and proven a training model for laparoscopic donor nephrectomy in pigs. This training model will allow surgeons to develop laparoscopic proficiency in a live donor, to be used in conjunction with human cadaveric training.

Abstract
The 2017 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline on the Evaluation and Care of Living Kidney Donors is intended to assist medical professionals who evaluate living kidney donor candidates and provide care before, during and after donation. The guideline development process followed the Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach and guideline recommendations are based on systematic reviews of relevant studies that included critical appraisal of the quality of the evidence and the strength of recommendations. However, many recommendations, for which there was no evidence or no systematic search for evidence was undertaken by the Evidence Review Team, were issued as ungraded expert opinion recommendations. The guideline work group concluded that a comprehensive approach to risk assessment should replace decisions based on assessments of single risk factors in isolation. Original data analyses were undertaken to produce a "proof-in-concept" risk-prediction model for kidney failure to support a framework for quantitative risk assessment in the donor candidate evaluation and defensible shared decision making. This framework is grounded in the simultaneous consideration of each candidate's profile of demographic and health characteristics. The processes and framework for the donor candidate evaluation are presented, along with recommendations for optimal care before, during, and after donation. Limitations of the evidence are discussed, especially regarding the lack of definitive prospective studies and clinical outcome trials. Suggestions for future research, including the need for continued refinement of long-term risk prediction and novel approaches to estimating donation-attributable risks, are also provided.In citing this document, the following format should be used: Kidney Disease: Improving Global Outcomes (KDIGO) Living Kidney Donor Work Group.
