Abstract
INTRODUCTION Grafts with multiple renal arteries (MRAs) were historically considered a relative contraindication to transplantation due to the higher risk of vascular and urologic complications. This study aimed to evaluate graft and patient survival between single renal artery (SRA) and MRA living-donor kidney transplants. METHODS An electronic literature search was conducted on PubMed, EMBASE, and Scopus for prospective or retrospective studies comparing SRA versus MRA in living donor renal transplantation, with the provision of Kaplan-Meier curves for recipient overall survival (OS) or graft survival (GS). A graphical reconstructive algorithm was used to obtain OS and GS of individual patients, which was then pooled under random-effects individual patient data (IPD) meta-analysis using Cox-models to determine hazard ratios (HRs) and 95% confidence intervals (CIs). Meta-regression of baseline covariates versus HRs of OS and GS was performed for variables reported in 10 or more studies. RESULTS Fourteen studies were retrieved, of which 13 (8400 patients) reported OS and 9 (6912 patients) reported GS. There were no significant differences in OS (shared-frailty HR = .94, 95%CI = .85-1.03, p = .172) or GS (shared-frailty HR = .95, 95%CI = .83-1.08, p = .419) between SRA and MRA. This comparison remained non-significant even when restricted to open- or laparoscopic-only studies. Meta-regression yielded no significant associations of GS with donor age, recipient age, and percentage of double renal arteries within the MRA arm. CONCLUSIONS The similar rates of GS and OS between MRA and SRA grafts suggest that there is no need for discrimination between the two when evaluating donors for nephrectomy.

The effect of single or multiple arteries in the donor kidney on renal transplant surgical outcomes. Ir J Med Sci 2022; 192:929-934. [PMID: 35697967 DOI: 10.1007/s11845-022-03024-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Accepted: 04/26/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND As the number of end-stage renal disease (ESRD) patients is increasing, but there are not enough living donors, it is necessary to broaden the criteria for candidates who can undergo donor nephrectomy. Thanks to surgeons' increasing experience with laparoscopic donor nephrectomy (LND), multiple renal artery grafts, previously considered a relative contraindication to donor nephrectomy, have become candidates for LDN. We aimed to compare the outcomes of donors and recipients with single artery and with multiple arteries in LDN. METHODS A total of 214 patients were included in the study. Patients were divided into two groups according to the number of donor arteries: donors with one artery (group 1) and donors with multiple arteries (group 2). The number of donor arteries, operative time, warm ischemia time (WIT), cold ischemia time (CIT), arterial anastomosis time, venous anastomosis time, the extent of bleeding, and preoperative complications were recorded to evaluate the preoperative data. RESULTS The mean operation time in group 1 was 90.3 ± 11.8 min, while in group 2, it was 102.1 ± 5.5 min (p = 0.000). WIT group 1 was 90.9 ± 4.3 s and group 2 100.6 ± 2.1 s (p = 0.000). Arterial anastomosis time was 12.25 ± 3.8 in group 1 and 22.5 ± 4.5 in group 2 (p = 0.000). No statistically significant difference was found between the two groups in other parameters. CONLUSION Increasing the number of donor arteries in renal transplantation (RT) operations prolonged the operation time on both the donor and recipient sides. Still, it had no negative impact on complications or graft function in the postoperative period.

Creating a Single Inflow Orifice From Living Donor Kidney Allografts With Multiple Renal Arteries. Transpl Int 2022; 35:10212. [PMID: 35497891 PMCID: PMC9046561 DOI: 10.3389/ti.2022.10212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 03/08/2022] [Indexed: 11/15/2022]
Abstract
Background: Multiple renal arteries (MRA) are often encountered during living-donor kidney transplantation (LDKT), requiring surgeons to pursue complex renovascular reconstructions prior to graft implantation. With improvements in reconstruction and anastomosis techniques, allografts with MRA can be successfully transplanted with similar outcomes to allografts with a single renal artery. Here, we describe in detail various surgical techniques for reconstruction of MRA grafts with the intent of creating a single arterial inflow. Methods: We retrospectively reviewed the medical records of all LDKT recipients with laparoscopically procured MRA kidneys between March 2008 and July 2021. Recipient and donor characteristics, operative data, type of reconstruction, and recipient outcomes were analyzed. The primary outcomes were the incidence of developing delayed graft function (DGF) and/or a vascular or urological complication within 12 months post-transplant. Results: Seventy-three LDKT recipients of MRA donor allografts were evaluated. Two renal arteries (RA) were encountered in 62 allografts (84.9%) and three RA in 11 allografts (15.1%). Renal artery reconstruction was performed in 95.8% (70/73) of patients. Eighteen different reconstruction techniques of MRA were utilized, the most common being side-to-side anastomosis in allografts with two RA (N = 44) and side-to-side-to-side anastomosis in allografts with three RA (N = 4). Interposition grafting was performed in seven cases (9.6%). A single ostium was created in 69 cases (94.5%), and the median warm ischemia time was 27 (range 20–42) minutes. None of the patients developed DGF or post-operative vascular or urological complications. Median creatinine at 3, 6, and 12 months post-transplant remained stable at 1.1 mg/dl. With a median follow-up of 30.4 months post-transplant, only one graft failure has been observed–death-censored graft survival was 98.6%. Conclusion: Complex reconstruction techniques to create a single renal artery ostium for graft implantation anastomosis in allografts with MRA show acceptable warm ischemic times, with no increased risk of post-operative vascular or urological complications.

Abstract
Background and Purpose Vascular multiplicity is the most frequent anatomic variation in kidney donors. Despite concerns about risks, these allografts are increasingly used to overcome the shortage of kidney donors. The safety and clinical outcomes in living kidney donors were evaluated with vascular multiplicity after hand-assisted laparoscopic living donor nephrectomy (HALDN). Patients and Methods Data from all living kidney donors who underwent HALDN from 2008 to 2021 was retrospectively reviewed. Patients were divided into two groups as single (SRV) and multiple renal vessels (MRV), and a comparative analysis was done. The primary outcomes include operating room time (ORT), days of hospital stay, estimated blood loss, complications, conversion, and re-operations. Results MRV were present in 166 out of 612 donors (27.1%). Among those, 10 (1.6%) donors had simultaneous multiple arteries and veins. Additionally, the prevalence of artery and vein multiplicity was 21.8% (n = 134) and 3.5% (n = 22), respectively. Warm ischemia time was significantly different among the two groups but not clinically important. The number of conversions to open technique, the mean ORT, the median blood loss, and days of hospital stay were similar between the SRV and MRV groups, without significant differences. According to the modified Clavien-classification system, no differences were found in the complication rates between the two groups (p = 0.29). Complication rates were 3.3% and 3.6% for the SRV and MRV groups, respectively. Conclusion HALDN is a procedure with safe intraoperative results, even with vascular multiplicity. The presence of multiple renal arteries or veins has no negative impact on the outcome of the donor after living donor nephrectomy.

Abstract
Background: The use of living-donor kidney allografts with multiple vessels continues to rise in order to increase the donor pool. This requires surgeons to pursue vascular reconstructions more often, which has previously been associated with a higher risk of developing early post-transplant complications. We therefore wanted to investigate the prognostic role of using living-donor renal allografts with a single artery (SA) vs. multiple arteries (MA) at the time of transplant. Methods: We retrospectively analyzed a cohort of 210 consecutive living-donor kidney transplants performed between January, 2008 and March, 2019, and compared the incidence of developing postoperative complications and other clinical outcomes between SA vs. MA recipients. Results: No differences were observed between SA (N = 161) and MA (N = 49) kidneys in terms of the incidence of developing a postoperative (or surgical) complication, a urologic complication, hospital length of stay, delayed graft function, estimated glomerular filtration rate at 3 or 12 mo post-transplant, and graft survival. Conclusions: The use of live-kidney allografts with MA requiring vascular reconstruction shows excellent clinical outcomes and does not increase the risk of developing postoperative complications or other adverse outcomes when compared with SA renal allografts.

Abstract
Introduction: In kidney transplantation, total laparoscopic live donor nephrectomy (TLLDN) in the presence of multiple renal arteries (MRA) is technically challenging and has traditionally been associated with higher complication rates. We report our experience of using MRA grafts procured by TLLDN. Materials and Methods: Patients undergoing TLLDN at our center (2004–2014) was identified from a prospectively maintained database and divided into single renal arteries (SRA) or MRA groups. Recipient perioperative parameters, postoperative complications, and long-term graft survival were analyzed. Results: Of 465 patients, 106 had MRA and 359 had an SRA. There were six vascular complications in the SRA group and two in the MRA group (1.7% vs. 1.8%). There were eight ureteric complications requiring intervention in the SRA group compared to three in the MRA group (4% vs. 3%; P = 0.45). Acute rejection was observed in 12% of the SRA group compared to 9% in the MRA group (P = 0.23). One-, 5- and 10-year graft survivals were 98.2%, 91.3%, and 89.8% in the MRA group versus 98.0%, 90.4%, and 77.5% in the SRA group (log-rank P = 0.13). Conclusion: The use of MRA grafts procured by TLLDN has comparable complication rates to SRA grafts and should not preclude selection for renal transplantation.

Abstract
BACKGROUND Renal grafts with multiple renal arteries (MRA) are a compelling issue in surgery of kidney transplantation. Transplantations using "grafts with MRA" have conflicting results. Here, we present our experiences on the issue. METHOD This is a single-center, observational, descriptive study. One hundred ninety-nine patients with end-stage renal disease received a kidney graft from their living- or deceased-related donors in our center between July 2016 and May 2017. We included all recipients to the study. Patients were divided into the following 2 groups: Group 1, recipients who received a renal graft with single renal artery, and Group 2, recipients who received a renal graft with MRA. Groups were compared for estimated glomerular filtration rates (months 1-3 and 12), delayed graft function, and graft survival. Data were analyzed by using SPSS for Windows version 15. RESULTS One hundred ninety-five recipients with all documented data were analyzed. Graft function was compared between 2 groups in months 1, 3, and 12 and found both to have similar outcomes. MRA has been indicated to have no impact on delayed graft function, higher risk for vascular injury, and biopsy-proven acute tubular necrosis. Also, anastomosis sides have been found to have no importance on graft function in recipients with MRA (P > .05 between all sides). CONCLUSION Our study indicates grafts with MRA and grafts with a single renal artery have comparable results in the first post-transplant year.

Abstract
PURPOSE To access the current status of the security and feasibility of right kidney (RK) and multiple-renal artery (MRA) laparoscopic living donor nephrectomy (LLDN) which are more challenging compared to left kidney (LK) and single renal artery (SRA) because of a shorter renal vein and more complex vascular anatomy. METHODS We did a systematic review of the literature according to the PRISMA recommendations, reporting RK or MRA donor nephrectomy performed with a laparoscopic technique compared to LK or SRA kidney LLDN. The identified and analyzed primary outcomes of interest were operating time (OT), warm ischemia time (WIT), rate of conversion and transfusion, donor length of stay (LOS), delayed graft function (DGF) and rate of graft loss (GL). RESULTS 16 comparative studies (1397 cases) of RK-LLDN and 12 comparative studies including 15 series (993 cases) of MRA-LLDN were selected. For RK-LLDN review, conversion rate was 0.8% and blood transfusion rate 0.2%, only one case of graft venous thrombosis was reported, OT was shorter in four studies and there was no any difference of DGF and GL rate compared to LK-LLDN. For MRA-LLDN review, conversion rate was 1.3% and blood transfusion rate 1.1%, OT and WIT were longer compared to SRA-LLDN, there were more ureteral complications in two studies, and no difference in terms of vascular complications and graft loss rate. CONCLUSION RK-LLDN and MRA-LLDN would be similar to LK-LLDN and SRA-LLDN in terms of feasibility and safety for the donor as well as graft function results for RK-LLDN.

Abstract
Objectives The aim of our study was to determine the efficacy of preoperative early arterial Computed tomography angiography (CTA) in donor nephrectomy, to assess the renal arterial and venous structures of donor kidneys. Materials and Methods Seventy living donor candidates were included to this study, who had CTA for the assessment of their renal vessels in our hospital between January 2011 and January 2015. Only early arterial phase images were obtained to avoid exposing the patients from high dose of radiation. Scans were reported by two radiologists independently. The number of renal arteries, veins and their tributaries were documented. The donor kidneys were removed by two consultant surgeons, and after back-table perfusion the same details were recorded and taken as the reference findings for the operation side. Results A total of 70 potential live kidney donors underwent renal CTA, among them fifty five patients had donor nephrectomy. A total of 140 kidneys were evaluated by CTA and the vessels of 55 harvested kidneys were compared with CTA findings. There were 40 kidneys that had at least one accessory or polar artery. There were 5 early branching renal arteries, two retroaortic and two circumaortic renal veins. Three kidneys had multiple renal veins. Operation findings were totally consistent with CTA findings in patients who underwent donor nephrectomy. Conclusion Arterial phase CTA is sufficient for evaluation of both arterial and venous vessels of kidneys, and precontrast, venous or late phase imaging should be preserved only for chosen circumstances to avoid high radiation exposure.

Abstract
Living donor kidneys with two arteries can be revascularized using various techniques depending on anatomy. We hypothesized that the revascularization technique could impact long-term outcomes. We retrospectively analyzed 1714 living donor renal transplants at our institution between 1999 and 2015. Three hundred and eleven kidneys had dual arteries, and these were categorized into 5 groups; end-to-side (n = 18), inferior epigastric artery (n = 21), direct anastomosis (n = 65), side-to-side (n = 126) and ligated (n = 81). We then compared the outcomes with that of a control group (single artery, n = 1403) using Kaplan-Meier and Cox regression analyses. Cox regression was adjusted by age, sex and race/ethnicity of donor and recipient, side of kidney, transplant period and recipient surgeon. Compared to the control group, the end-to-side group had increased all-cause graft loss (10 years: 77.2% vs 24.5%, adjusted hazard ratio [aHR] 3.02, 95% confidence interval [CI] 1.30–7.03, p = 0.010) and death-censored graft loss (10 years: 82.0% vs 55.9%, aHR 4.17, 95% CI 1.63–10.68, p = 0.003), whereas the other groups did not. Our study shows that 10-year overall survival and death-censored graft survival were significantly worse for end-to-side arterial reconstruction than for other techniques. Alternative techniques to the end-to-side method should be used for accessory arteries that require revascularization.

Abstract
On the 60th anniversary of the first successfully performed renal transplantation, we summarize the historical, current and potential future status of kidney transplantation. We discuss three different aspects with a potential significant influence on kidney transplantation progress: the development of surgical techniques, the influence of regenerative medicine and tissue engineering, and changes in immunosuppression. We evaluate the standard open surgical procedures with modern techniques and compare them to less invasive videoscopic as well as robotic techniques. The role of tissue engineering and regenerative medicine as a potential method for future kidney regeneration or replacement and the interesting search for novel solutions in the field of immunosuppression will be discussed. After 60 years since the first successfully performed kidney transplantation, we can conclude that the greatest achievements are associated with the development of surgical techniques and with planned systemic immunosuppression.

Vascular Multiplicity Should Not Be a Contra-Indication for Live Kidney Donation and Transplantation. PLoS One 2016; 11:e0153460. [PMID: 27077904 PMCID: PMC4831799 DOI: 10.1371/journal.pone.0153460] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2015] [Accepted: 03/30/2016] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Whether vascular multiplicity should be considered as contraindication and therefore 'extended donor criterion' is still under debate. METHODS Data from all live kidney donors from 2006-2013 (n = 951) was retrospectively reviewed. Vascular anatomy as imaged by MRA, CTA or other modalities was compared with intraoperative findings. Furthermore, the influence of vascular multiplicity on outcome of donors and recipients was studied. RESULTS In 237 out of 951 donors (25%), vascular multiplicity was present. CTA had the highest accuracy levels regarding vascular anatomy assessment. Regarding outcome of donors with vascular multiplicity, warm ischemia time (WIT) and skin-to-skin time were significantly longer if arterial multiplicity (AM) was present (5.1 vs. 4.0 mins and 202 vs. 178 mins). Skin-to-skin time was significantly longer, and complication rates were higher in donors with venous multiplicity (203 vs. 180 mins and 17.2% vs. 8.4%). Outcome of renal transplant recipients showed a significantly increased WIT (30 vs. 26.7 minutes), higher rate of DGF (13.9% vs. 6.9%) and lower rate of BPAR (6.9% vs. 13.9%) in patients receiving a kidney with AM compared to kidneys with singular anatomy. CONCLUSIONS We conclude that vascular multiplicity should not be a contra-indication, since it has little impact on clinical outcome in the donor as well as in renal transplant recipients.

Abstract
As the organ shortage increases, inherently the demand for donor kidneys continues to rise. Thus, live kidney donation is essential for increasing the donor pool. In order to create successful expansion, extended criteria live kidney donors should be considered. This review combines current guidelines with all available literature in this field, trying to seek and establish the optimal extended criteria. Comprehensive searches were carried out in major databases until November 2013 to search for articles regarding older age, overweight and obesity, hypertension, vascular anomalies/multiplicity, nulliparous women, and minors as donors. Of the 2079 articles found, 152 fell within the scope of the review. Five major guidelines were included and reviewed. Based on the literature search, live kidney donation in older donors (up to 70 years of age) seems to be safe as outcome is comparable to younger donors. Obese donors have comparable outcome to lean donors, in short- and mid-term follow-up. Since little literature is available proving the safety of donation of hypertensive donors, caution is advised. Vascular multiplicity poses no direct danger to the donor and women of childbearing age can be safely included as donors. Although outcome after donation in minors is shown to be comparable to adult donors, they should only be considered if no other options exist. We conclude that the analyzed factors above should not be considered as absolute contraindications for donation.

Abstract
PURPOSE To determine which measurement of donor renal size on computed tomographic (CT) angiograms has the greatest correlation with renal function preoperatively in the donor and postoperatively in the transplant recipient. MATERIALS AND METHODS Informed consent was waived for this retrospective HIPAA-compliant study approved by the institutional review board. Renal length, total volume, and cortical volume were measured on renal donor CT angiograms in 111 patients. Preoperative serum creatinine values for donors and postoperative creatinine values for recipients at hospital discharge and 6, 12, 24, and 36 months after transplant were collected, and estimated glomerular filtration rate (eGFR) was calculated. Correlation coefficients with 95% confidence intervals (CIs) were obtained for renal measures and donor eGFR and for renal measures adjusted to recipient body habitus and posttransplant creatinine level in the recipient. Thresholds were set for adjusted length and volumes, and the odds ratio (OR) for creatinine level less than 1.5 mg/dL at 36 months was calculated. RESULTS Renal volumes and length were correlated with donor eGFR (r=0.58 [95% CI: 0.44, 0.69] for cortical volume, 0.56 [95% CI: 0.42, 0.68] for total volume, and 0.43 [95% CI: 0.27, 0.57] for renal length). All three measures, adjusted to recipient body habitus, were correlated with recipient renal function from discharge (r=-0.41 to -0.43) up to 36 months after transplantation (r=-0.33 to -0.41). By using a threshold of 1.5 for cortical volume to recipient weight, 2.25 for total volume to recipient weight, and 0.175 for renal length to recipient weight, the odds of creatinine level greater than 1.5 mg/dL were four times as great for smaller kidney-to-recipient weight ratios, a statistically significant pattern for cortical volume (OR, 4.07; 95% CI: 1.10, 15.09) but not total volume (OR, 4.24; 95% CI: 0.90, 20.01) or renal length (OR, 4.08; 95% CI: 0.48-34.29). CONCLUSION Renal length and volumes correlated with recipient renal function up to 36 months after transplant. A low ratio of cortical volume to recipient weight was associated with diminished renal function at 36 months after transplant.
