    Abstract Aims: The objective of this survey was to encompass the full scope of international practice, entailing all technical, non-technical, preoperative stratification and functional maturation (FM) of RCAVF.
    Methods: The survey contained
    Results: FM is independently associated with volume of surgeon per year (procedures performed) (
    Conclusion: FM in RCAVF is independently & incrementally associated with the volume of surgeon per year. There is a diverse inclusion, exclusion and technical approach in RCAVF creation. This survey advocates the importance of international collaboration and/or registry in assimilation, consolidate and development of consensus.

    Abstract Current international guidelines advocate fistula creation as first choice for vascular access in haemodialysis patients, however, there have been suggestions that in certain groups of patients, in particular the elderly, a more tailored approach is needed. The prevalence of more senior individuals receiving renal replacement therapy has increased in recent years and therefore including patient age in decision making regarding choice of vascular access for dialysis has gained more relevance. However, it seems that age is being used as a surrogate for overall clinical condition and it can be proposed that frailty may be a better basis to considering when advising and counselling patients with regard to vascular access for dialysis. Frailty is a clinical condition in which the person is in a vulnerable state with reduced functional capacity and has a higher risk of adverse health outcomes when exposed to stress inducing events. Prevalence of frailty increases with age and has been associated with an increased risk of mortality, hospitalisation, disability and falls. Chronic kidney disease is associated with premature ageing and therefore patients with kidney disease are prone to be frailer irrespective of age and the risk increases further with declining kidney function. Limited data exists on the relationship between frailty and vascular access, but it appears that frailty may have an association with poorer outcomes from vascular access. However, further research is warranted. Due to complexity in decision making in dialysis access, frailty assessment could be a key element in providing patient-centred approach in planning and maintaining vascular access for dialysis.

    Abstract Background-objectives: Current evidence based on retrospective and prospective studies demonstrates that donation after circulatory death (DCD) grafts are more susceptible to delayed graft function (DGF) than donation after brain death (DBD) grafts. The short- and long-term survival outcomes of the two cohorts are unclear. Therefore, we performed a systematic review and meta-analysis to estimate the patient and allograft survival outcomes for DCD and DBD in renal transplant surgery.
    Methods: Systematic literature searches were conducted by searching various databases. Fixed and random effects models were used to assess the accumulation of evidence over time.
    Results: The five-year patient survival rate was significantly better in the DBD than in the DCD cohort. Non-significant differences were observed in 1-, 3- and 10-year patient survival and in the 1-, 3-, 5-, and 10-year graft survival rates between the two cohorts. The acute rejection rate was lower in the DCD cohort than in the DBD cohort. Extended criteria of donor status, delayed graft function and primary non-function were significantly higher in the DCD cohort than in the DBD cohort.
    Conclusions: This study demonstrates that the short- and long-term survival graft and patient benefits are similar between DCD and DBD kidney transplants. Therefore, large, controlled DCD kidney programmes are urgently needed worldwide in order to increase the number of kidney transplants.

  5. Article ; Online: Is there a role of the kidney failure risk equation in optimizing timing of vascular access creation in pre-dialysis patients?

    Abstract Background: The aims of this study were to assess the utility of using the Kidney Failure Risk Equation (KFRE) as an indicator to guide timing of vascular access creation in pre-dialysis patients.
    Materials and methods: Patients referred for vascular access creation had KFRE calculated at the time of assessment and compared to standard criteria for referral. Receiver operating characteristic curves were produced for each parameter. The outcomes at 3 months, 6 months, and 1 year were used as time points for analysis.
    Results: Two hundred and three patients were assessed, and full data sets were available on 190 (94.6%). Access was created in 156 patients (82.1%) with a fistula in 153 (98.7%). Only 65.7% initiated dialysis within the follow up period. Those patients with an AV access created (n = 156) 37 (23.7%) did not reach end stage over the entire follow up period. Of the remaining patients (n = 119) that reached end stage 72.2% (n = 86) started on an AVF/AVG and 27.7% (n = 33) on a CVC. Using ROC analysis for referral eGFR, ACR and KFRE predicting dialysis initiation predictors resulted in C statistics for eGFR, ACR, and KFRE2 of 0.68 (0.58-0.79), 0.75 (0.65-0.84), and 0.72 (0.62-0.81) at 3 months; 0.73 (0.65-0.81), 0.70 (0.62-0.78), and 0.75 (0.67-0.81) at 6 months; and 0.65 (0.57-0.72); 0.67 (0.59-0.75), and 0.68 (0.61-0.77) at 12 months.
    Conclusions: In a group of patients referred for vascular access creation the predictive models are relatively poor when applied to initiation of dialysis. The application of current guidelines to fistula creation appears to result in a high rate of unnecessary fistula formation and non-use. The study requires further evaluation in a test set of patients to confirm these findings and also identify where such risk based approaches may need modification.

    Abstract The quest for suitable conduits for dialysis access has continued since the first patients were dialysed. Whilst synthetic grafts made from expanded polytetrafluoroethylene (ePTFE) have been the main definitive option after autologous arteriovenous fistulas they have a number of drawbacks, which has led to the use and development of biological grafts such as autografts, homografts or xenografts. Technology continues to improve and currently biosynthetic options are available which may combine the benefits of a readily available product without the drawbacks of PTFE. The history and evidence of biological options for haemodialysis access are discussed.

    Abstract Internationally, vascular access (VA) surgery is delivered in a varied and diverse fashion and subsequently, training in vascular access is poorly defined. Experience of VA during surgical training has implications on future practice. The scope of VA procedures is increasing, yet the focus in vascular training remains largely in the technical aspects of surgery rather than the more comprehensive aspects of surgery applied to dialysis and renal care. To achieve special skills in vascular access surgery may require a change to traditional training with an additional focus on developing an extended portfolio of knowledge and skills. A small number of specialized courses and training facilities are developing to address these issues.

    Abstract The timing of referral for creation of vascular access in a patient with declining kidney function is difficult to predict. Current methods may result in patients undergoing unnecessary procedures and subsequent interventions on accesses that are never used. Multiple variables, including time for assessment, surgery and follow-up that considers the likelihood of access failure, and the estimated rate of kidney function decline, make vascular access planning challenging and difficult to balance. Better prediction tools that incorporate the risks of progressive decline in kidney function with the risk of access failure and the competing risk of death would facilitate decision-making in vascular access. The kidney failure risk equation is a validated, simple online tool that estimates the probability of the 2- and 5-year risk of reaching end-stage kidney disease. While the use of the kidney failure risk equation has not been validated as an adjunct to planning vascular access, it has potential and may facilitate more individualised care and more appropriate allocation of resources.
