Incisional Hernia Repaired Using Thigh Muscle Fascia After Kidney Transplantation: A Case Report

BackgroundAlthough monofilament mesh-based repair is a safe and effective procedure for incisional hernia (IH) in organ transplant patients, there is no definite evidence of IH treatment for patients with graft rejection and enhanced immunosuppressive therapy. We report a successful case of large IH repair using an autologous thigh muscle fascia sheet in a kidney transplant patient.Case PresentationA 69-year-old man had IH from the incision of kidney transplantation, which was performed 6 years ago. He had a large right lower abdominal distension hanging down to the inguinal portion. A computed tomography scan revealed a large IH with a maximum abdominal defect diameter of 15 cm. The hernia sac contained the intestine, colon, and transplanted kidney, which had pulled out along with the retroperitoneum and protruded into the abdominal wall. He had chronic active acute antibody-mediated rejection, which required frequent steroid pulse therapy and additional or adjusted immunosuppressive drugs. After total circumferential exposure of the hernia sac and abdominal fascia, the abdominal wall defect was closed using a horizontal mattress suture. The sutured line was covered with a thigh muscle fascia sheet harvested from the patient's right femur and attached to the closed fascia. He was discharged on postoperative day 13 without any complications, and no IH recurrence was observed 10 months after surgery.ConclusionsHernia repair using autologous tissue could be a treatment option for post-transplant IH with a higher risk of infection.     

Kidney Transplantation for a Patient With Protein C Deficiency Using Activated Protein C Concentrate: A Case Report

BackgroundThrombophilia causes thrombosis after kidney transplantation (KT). Protein C deficiency is a rare form of hereditary thrombophilia. To our knowledge, there are few reports on KT for patients with protein C deficiency, and there are no reports of KT in patients with protein C deficiency administered with activated protein C concentrate.MethodHere we reported the case of a patient with protein C deficiency who underwent KT without the occurrence of any fresh thrombosis after administration of an activated protein C concentrate. The patients was a 49-year-old woman diagnosed with immunoglobulin A nephropathy at 20 years of age. During pregnancy, she experienced deep vein thrombosis of the lower extremities and pulmonary embolism for which she was started on warfarin.After a thorough examination, the patient was diagnosed with protein C deficiency. The patient had end-stage kidney disease and received a preemptive living donor kidney transplant from her mother.ResultsTo prevent thrombosis, we switched from oral warfarin to continuous heparin 7 days before surgery. Heparin was discontinued 6 hours before surgery, and continuous activated protein C concentrate was administered 12 hours before surgery. Heparin administration was resumed 6 hours after the surgery. Warfarin administration was restarted 3 days after the surgery, and heparin was discontinued 11 days post-surgery. The surgery was performed without complications. After the KT, the patient's renal function steadily improved, and no fresh thrombosis were observed.ConclusionsThrombosis can cause graft loss and pulmonary embolism, thus appropriate administration of activated protein C concentrate may help prevent thrombosis.     

Strategies for prevention and control of the 2019 novel coronavirus disease in the department of kidney transplantation

To summarize measures for the prevention and control of the 2019 novel coronavirus disease (COVID-19) in the department of kidney transplantation. We retrospectively analyzed the clinical data of outpatients and inpatients in the department of kidney transplantation from January 20 to March 1, 2020, and followed up the in-home kidney transplant recipients and those waiting for kidney transplantation through the Internet platform. Our department had formulated detailed prevention and control measures, mainly including kidney transplant outpatient management, kidney transplantation ward management, management of kidney transplant surgery, dialysis management of patients waiting for kidney transplantation, personal protection of medical staff, and follow-up management of discharged patients after kidney transplantation. During the epidemic period, there were no COVID-19 cases among 68 outpatient examined kidney transplant recipients, 32 hospitalized kidney transplant recipients, 19 patients waiting for kidney transplantation in hospital, and 30 medical staff. There were no COVID-19 cases among 160 follow-up recipients after kidney transplantation and 60 patients waiting for kidney transplantation. During the epidemic period, we implemented strict prevention and control measures and adjusted working methods and procedures to ensure safe and orderly work of the department.     

Policies to promote timely referral for kidney transplantation

There are numerous patient, provider, and health system barriers to accessing kidney transplantation. Patient barriers such as sociocultural and clinical characteristics and provider factors such as provider knowledge and awareness of transplantation play important roles in facilitating transplant. Health system factors like misaligned incentives and quality metrics for dialysis facilities and transplant centers also influence transplant access. While numerous studies have documented the impact of these barriers on wait-listing and transplant, few studies have examined referral from a dialysis facility to a transplant center and start of the transplant evaluation process. While the Centers for Medicare and Medicaid Services (CMS) require that dialysis facilities educate patients about transplant, there are no guidelines for the content and objectives for this education. In addition, policies to require timely referral for transplantation have been considered by CMS but are difficult to implement without national data on referral. Federal policies should be amended to mandate transplant center submission of referral data—while decreasing the unfunded mandate to collect other unusable data currently collected as part of regulatory monitoring of transplant centers—to promote timely access to transplant, increased transplant rates, and to better understand the multilevel barriers and facilitators to transplant referral.     

Dialysis facility referral and start of evaluation for kidney transplantation among patients treated with dialysis in the Southeastern United States

Variability in transplant access exists, but barriers to referral and evaluation are underexplored due to lack of national surveillance data. We examined referral for kidney transplantation evaluation and start of the evaluation among 34 857 incident, adult (18‐79 years) end‐stage kidney disease patients from 690 dialysis facilities in the United States Renal Data System from January 1, 2012 through August 31, 2016, followed through February 2018 and linked data to referral and evaluation data from nine transplant centers in Georgia, North Carolina, and South Carolina. Multivariable‐adjusted competing risk analysis examined each outcome. The median within‐facility cumulative percentage of patients referred for kidney transplantation within 1 year of dialysis at the 690 dialysis facilities in Network 6 was 33.7% (interquartile range [IQR]: 25.3%‐43.1%). Only 48.3% of referred patients started the transplant evaluation within 6 months of referral. In multivariable analyses, factors associated with referral vs evaluation start among those referred at any time differed. For example, black, non‐Hispanic patients had a higher rate of referral (hazard ratio [HR]: 1.22; 95% confidence interval [CI]: 1.18‐1.27), but lower evaluation start among those referred (HR: 0.93; 95% CI: 0.88‐0.98), vs white non‐Hispanic patients. Barriers to transplant varied by step, and national surveillance data should be collected on early transplant steps to improve transplant access.     

Breathlessness and Respiratory Disability After Kidney Transplantation

BackgroundDyspnea is a common symptom in patients with end-stage kidney disease being treated with dialysis. This study aimed to ascertain the level of respiratory disability in patients after kidney transplantation through assessing a cohort of kidney allograft recipients for respiratory compromise and thereby identifying a potential target for therapeutic intervention.MethodsKidney transplant recipients who were under active observation in a single tertiary referral center were invited to take part in this prevalence study at the time of clinic follow-up. All patients agreed to take part in the study, which involved completing a Medical Research Council (MRC) dyspnea scale, completing the St George's Respiratory Questionnaire, and performing basic spirometry. An MRC score of ≥2 and/or a forced expiratory volume in 1 second <90% predicted prompted formal clinical assessment by a respiratory physician.ResultsThis study enrolled 103 patients; 35% of all patients reported breathlessness, and 56% of all patients warranted formal respiratory medicine review. After completion of their investigations, 33 patients were found to have an underlying condition accounting for their symptoms.ConclusionOur study highlights the issues of respiratory disability and breathlessness in patients who have undergone kidney transplantation. Although extensive cardiologic evaluation is performed routinely and can rule out many causes of dyspnea, respiratory assessment is not a preoperative prerequisite. This study could suggest that a formal pulmonological evaluation and basic spirometry should be part of the pretransplant evaluation of the kidney transplant recipient.     

Hip Arthroplasty Outcomes in the Presence of Kidney Failure: A National Data Linkage Study

BackgroundPatients who have kidney failure are at higher risk of requiring total hip arthroplasty (THA) and are at higher risk of complications. This study compared the rate of revision surgery and mortality following THA between patients who have kidney failure receiving long term dialysis or who had a kidney transplant and those who did not have kidney failure.MethodsA data linkage study was performed using data from 2 national registries: a registry of dialysis and kidney transplant patients and a registry of THA procedures. Both registries had coverage of almost all procedures or treatments in Australia. Data from September 1999 to December 2016 were used. Mortality and revision surgery were compared between patients receiving dialysis, those who had a functioning kidney transplant, and patients who did not have kidney failure using Cox and Fine-Gray (competing risk) regression models. A total of 383,478 primary THA procedures were identified as people receiving dialysis (n = 490), who had a functioning kidney transplant (n = 459), or who did not have kidney failure (n = 382,529).ResultsThere was no significant difference in the overall rate of revision surgery between the groups (dialysis versus no kidney failure HR = 1.20; 95% CI 0.76, 1.88, transplant versus no kidney failure (hazard ratio) HR = 1.01; 95% (confidence interval) CI 0.66, 1.53). The risk for death after surgery was significantly higher in the dialysis group compared to both the functioning transplant group (HR = 3.44; 95%CI 1.58, 7.5), and in those without kidney failure (HR = 4.13; 95%CI 3.25, 5.25).ConclusionThe rate of mortality after THA in patients on dialysis is higher than in patients who have a functioning transplant or those who do not have kidney failure, but there is no early excess mortality to suggest a difference in this metric due to the surgery.     

Clinical Practice of Steroid Avoidance in Pediatric Kidney Transplantation

Steroid‐avoidance protocols have recently gained popularity in pediatric kidney transplantation. We investigated the clinical practice of steroid avoidance among 9494 kidney transplant recipients at 124 transplant centers between 2000 and 2012 in the Organ Procurement and Transplantation Network database. The practice of steroid avoidance increased during the study period and demonstrated significant variability among transplant centers. From 2008 to 2012, 39% of transplant centers used steroid avoidance in <10% of all discharged transplant recipients. Twenty‐one percent of transplant centers practiced steroid avoidance in 10–40% of transplant recipients, and 40% of transplant centers used steroid avoidance in >40% of discharged patients. Children receiving steroid avoidance more frequently received induction with lymphocyte‐depleting agents. Repeat kidney transplants were the least likely to receive steroid avoidance. Children who received a deceased donor kidney, underwent pretransplant dialysis, were highly sensitized, or had glomerular kidney disease or delayed graft function were also less likely to receive steroid avoidance. The variation in practice between centers remained highly significant (p < 0.0001) after adjustment for all patient‐ and center‐level factors in multivariate analysis. We conclude that significant differences in the practice of steroid avoidance among transplant centers remain unexplained and may reflect uncertainty about the safety and efficacy of steroid‐avoidance protocols.     

Wünderlich Syndrome in Renal Transplant Recipients: A Case Report and Literature Review

BackgroundWünderlich syndrome, or spontaneous atraumatic renal hemorrhage, is a clinical entity rarely described in the native kidney of patients who have undergone renal transplant. Although its manifestation is quite similar in reported cases, it may present few symptoms, from bleeding of unidentified etiology to dramatic pictures associated with hypovolemic shock. There are few reports of spontaneous hemorrhage of a native kidney after kidney transplantation.Case reportWe present a 38-year-old male patient who developed hemorrhage of a ruptured native kidney after a late renal transplantation. We analyze what has been reported in the literature and highlight the possibility of this complication after kidney transplantation. Imaging exams and surgical specimen demonstrated the presence of ruptured angiomyolipoma in the patient's native right kidney. The postoperative period was not complicated, with a benign clinical evolution.ConclusionAlthough rare in patients who have undergone renal transplant, it is justified to suggest Wünderlich syndrome in the presence of acute flank pain, abdominal tenderness, and signs of internal bleeding (Lenk's triad), with unexplained hemoglobin drop.     

Lactated Ringer as Preservation Solution in Living Donor Renal Transplantation

BackgroundOptimal organ preservation remains a critical hallmark event in renal transplantation as it is the supply line. Previous studies have shown that the choice of preservation solution may affect transplant outcomes. In this study, we aimed to present the early follow-up results of the graft and patients, using lactated Ringer to preserve kidney allografts with living donors.MethodsThe results of 97 living donor transplant operations performed in Sanko University Hospital were evaluated retrospectively. The patient's evaluation included demographics, dialysis time duration, renal replacement method, primary disease, comorbidity, surgical and clinical complications in the acute period, graft functions, blood levels of calcineurin inhibitor drugs, anastomotic renal artery, warm ischemia, and cold ischemia times.ResultsDonor (49 men, 50.5%) and recipient (58 men, 59.7%) demographics, HLA compatibility (mismatch), hospitalization days, and length of warm and cold ischemic time are summarized in Table 1. Primary nonfunction was not defined in any patients, but delayed graft function was observed during the follow-up of 3 patients (3.09%), who were all hypotensive in the post-transplantation period, and positive inotropic infusion was needed for hemodynamic stability.ConclusionsLactated Ringer demonstrated efficacy in terms of patient and graft survival, and its lower cost represents a financial advantage, so it can be used in living donor kidney transplantation because it is safe, effective, and inexpensive. Standard preservation solutions may still be recommended in cases with long cold ischemia times, such as paired exchange transplants and cadaveric transplants. Thus, randomized controlled studies are needed for further investigation.     

Treatment of severe lactic acidosis during the pre-anhepatic stage of liver transplant surgery with intraoperative hemodialysis

Severe uncompensated lactic acidosis manifesting during the pre-anhepatic stage of orthotopic liver transplant surgery is an uncommon event, but it poses serious concern because of the additional lactate production and impaired elimination by the liver that develops during the anhepatic and allograft reperfusion stages of the procedure. A man with end-stage liver disease secondary to hepatitis C and hemochromatosis and normal renal function, who developed severe lactic acidosis in the pre-anhepatic stage of liver transplantation, was treated successfully with intraoperative, continuous venovenous hemodialysis. Hemodialysis effectively corrected the patient's lactic acidosis and removed lactate, which contributed to hemodynamic stability during the anhepatic and graft reperfusion stages of his liver transplant surgery.     

Lung Transplant as a Treatment for Patients with End-Stage Respiratory Failure Due to COVID-19

BackgroundCOVID-19 may lead to development of irreversible acute respiratory distress syndrome. Some patients sustain severe respiratory failure after infection subsides. They may require lung transplant as a last resort treatment. The aim of the study is to assess the effect and feasibility of lung transplant as a treatment for patients with severe irreversible respiratory failure due to COVID-19.MethodsThis retrospective study pertains to analysis of 119 patients in critical condition who were referred to Lung Transplant Ward (Zabrze, Poland). between July 2020 and June 2021 after developing respiratory failure requiring extracorporeal membrane oxygenation, invasive ventilation, or both, as well as a few patients on high-flow oxygen therapy. Inclusion criteria for referral were confirmed lack of viral disease and exhaustion of other therapeutic options.ResultsOf the referred patients, 21.84% were disqualified from such treatment owing to existing contraindications. Among the suitable patients, 75.8% died without transplant. Among all patients who were qualified for lung transplant, only 9 patients became double lung transplant recipients. Intraoperative mortality for this procedure was 33%. Four patients were discharged after the procedure and are currently self-reliant with full respiratory capacity.ConclusionsPatients with severe irreversible respiratory failure after COVID-19 present significantly high mortality without lung transplant. This procedure may present satisfactory results but must be performed in a timely fashion owing to critical condition and scarcity of lung donors, only aggravated around the time of peak infection waves.     

A Case Report of Successful Renal Transplantation After Surgically Treated Type A Aortic Dissection

BackgroundAortoiliac lesions can influence the results of kidney transplantation and increase technical difficulties during surgery. Aortic dissection (AD) is a rare and infrequently reported event before transplantation, whereas immediate optimal perfusion is paramount for kidney transplantation. Thus, adequate blood flow imposed by the flow from the true lumen must be considered when choosing a target inflow vessel.Case presentationA 67-year-old man on dialysis with end-stage renal disease caused by immunoglobulin A nephropathy was referred for kidney transplantation. He had successfully undergone conventional Stanford type A AD surgery 3 years ago. Pretransplant contrast-enhanced computed tomography angiography revealed termination of the distal intimal flaps within the common iliac arteries. Dilation of the descending aorta was also observed. Based on the meticulous vascular assessment, including consultation with the cardiovascular surgery department, the right internal iliac artery (IIA) was considered usable for anastomosis. He underwent living unrelated kidney transplantation from his 66-year-old wife. The patency and blood flow in the right IIA were also verified using intraoperative findings. Without any special procedure, we used a side-to-end arterial anastomosis between the donor renal artery and recipient IIA. After vascular clamp removal, the allograft was perfused homogeneously and immediately functioned.ConclusionPatients receiving previous surgery for type A AD can successfully undergo kidney transplantation if the patency of the iliac arteries from the true lumen is confirmed by perioperative evaluation, and the artery can be carefully clamped to avoid possible further dissection.     

Endometrial Cancer After Pancreas-After-Kidney Transplantation: A Case Report and Review of the Literature

BackgroundAs the number of long-term survivors after organ transplantation increases, malignancy has become a problem as a late complication. We herein report a case of endometrial cancer during the follow-up of pancreas transplantation after kidney transplantation.Case PresentationA 49-year-old woman was diagnosed with endometrial cancer. The patient had developed type 1 diabetes at 8 years old and started insulin treatment, and at 29 years old, she started hemodialysis for diabetic nephropathy. At 31 years old, she received living donor kidney transplantation and withdrew from dialysis. Hypoglycemia unawareness began to occur frequently from around 36 years old, and at 48 years old, the patient underwent deceased donor pancreas transplantation after kidney transplantation and achieved insulin independence. At 49 years old, she was diagnosed with endometrial cancer. Surgical treatment (total abdominal hysterectomy with left salpingo-oophorectomy) was performed. The pathologic diagnosis was confirmed as stage 1A uterine endometrioid carcinoma grade 1. The postoperative course was uneventful. She was discharged from our hospital on postoperative day 8. There has been no evidence of recurrence and/or metastasis of endometrial cancer for 16 months since the surgery.ConclusionsCarcinogenesis after pancreas transplantation may be a lethal late complication. It is important to carry out regular screening examinations with carcinogenesis in mind.     

Efficacy and Safety of Machine Perfusion for Brain Death Marginal Donor Kidney Transplantation: A Report of 2 Cases

BackgroundAfter the revised organ transplant law came into effect in Japan, donations of organs under brain death have been increasing; however, because of the expansion of donor indications, donations from expanded criteria donors and cardiac arrest donors (donation after cardiac death) have also increased. In kidney transplantation, ischemia-reperfusion injury results in a high rate of delayed graft function, which adversely affects patients’ long-term prognoses. Hypothermic machine perfusion preservation results in superior postoperative function and survival rates compared with cold storage preservation. We used an organ preservation device for kidneys and performed a graft viability evaluation before to kidney transplantation.MethodsWe used the CMP-X08 perfusion device (Chuo-Seiko Co, Ltd, Asahikawa, Hokkaido, Japan) and Belzer MPS solution to preserve the donated organ. The perfusion pressure and temperature were monitored during cold storage with continuous perfusion. Standard renal transplantation protocols were followed. A renal biopsy was performed 1 hour after transplantation and the renal function was evaluated. This study followed the principles of the Declaration of Helsinki.ResultsThe first presented case is of a 63-year-old woman who received a kidney from a middle-aged man with brain death due to hypoxic encephalopathy. The creatinine at the time of admission was 0.9 mg/dL and at the time of excision was 2.86 mg/dL. The total perfusion time was 120 minutes. The total ischemia time was 7 hours and 15 minutes. The recipient urinated 115 minutes postoperatively, and no dialysis was required. The second presented case is of a 47-year-old man with a 15-year history of dialysis who received a kidney from a middle-aged woman with brain death due to subarachnoid hemorrhage. The creatinine at the time of admission was 0.8 mg/dL and at the time of excision was 0.77 mg/dL. The total perfusion time was 240 minutes. The total ischemia time was 13 hours and 14 minutes. The recipient urinated 38 minutes postoperatively, and no dialysis was required.ConclusionsMechanical perfusion storage performed for 2 to 4 hours resulted in a viable organ that was successfully transplanted in both cases.     

Bariatric surgery prior to transplantation and risk of early hospital re-admission,graft failure,or death following kidney transplantation

Bariatric surgery has been shown to be safe in the dialysis population. Whether bariatric surgery before kidney transplantation influences posttransplant outcomes has not been examined nationally. We included severely obese (BMI >35) dialysis patients between 18 and 70 years who received a kidney transplant according to the US Renal Data System. We determined the association between history of bariatric surgery and risk of 30-day readmission, graft failure, or death after transplantation using multivariable logistic, Fine-Gray, and Cox models. We included 12 573 patients, of whom 503 (4%) received bariatric surgery before transplantation. Median age at transplant was 53 years; 42% were women. Overall, history of bariatric surgery was not statistically significantly associated with graft failure (HR 1.02; 95% CI 0.77–1.35) or death (HR 1.10; 95% CI 0.84–1.45). However, sleeve gastrectomy (vs. no bariatric surgery) was associated with lower risk of graft failure (HR 0.39; 95% CI 0.16–0.95). In conclusion, history of bariatric surgery prior to kidney transplantation was not associated with allograft or patient survival, but findings varied by surgery type. Sleeve gastrectomy was associated with better graft survival and should be considered in severely obese transplant candidates receiving dialysis.     

Lack or insufficient predialysis nephrology care worsens the outcomes in dialyzed patients – call for action

The phenomenon of patients with advanced renal failure accepted for dialysis at a late stage in the disease process (late referral [LR]) is known almost from the beginning of dialysis therapy. It may also be associated with worse outcomes. The aim of the study was to assess the effect of referral time on the outcomes, such as number of hospitalizations, length of stay, kidney transplantation, and mortality. A study of 1303 patients with end-stage renal failure admitted for dialysis in the same period in Fresenius Nephrocare Poland dialysis centers was initiated. The type of vascular access during the first dialysis was accepted as the criterion differentiating LR (n = 457 with acute catheter) from early referral (ER; n = 846). The primary endpoint was the occurrence of death during the 13-month observation. By the end of observation, 341 (26.2%) of patients died. The frequency of death was 18.1 for ER and 37.9 for LR per 1000 patient-months. It can be estimated that 52.1% (95% CI: 40.5–61.5%) of the 341 deaths were caused by belonging to the LR group. Patients from LR group had longer hospitalizations, more malignancies, lower rate of vascular access in the form of a–v fistula, higher comorbidity index. It seems that establishing a nephrological registry would help to improve the organization of care for patients with kidney disease, particularly in the pandemic era.     

Staged versus concurrent native nephrectomy and renal transplantation in patients with autosomal dominant polycystic kidney disease: A systematic review

BackgroundPatients with Autosomal Dominant Polycystic Kidney Disease (ADPKD) frequently undergo native nephrectomy before transplantation. The nephrectomy may be a staged procedure or undertaken simultaneously with transplantation. When performed simultaneously, the transplant procedure is more prolonged, involves a larger operative field and incision. There is also a concern of a greater risk of graft loss with simultaneous nephrectomy and transplantation. Moreover, staged surgery may allow nephrectomy to be performed before immunosuppression introduction via a smaller incision or involving a minimally invasive approach. However, staged nephrectomy may require a period of dialysis not otherwise necessary if a transplant and nephrectomy were simultaneous. Moreover, only a single procedure is needed, implying the avoidance of a prior nephrectomy and its attendant morbidity in a patient with chronic renal insufficiency. To account for these issues, this study aims to compare the cumulative morbidity of two-staged procedures versus a single simultaneous approach in term of morbidity and graft outcomes.ObjectivesThis study aims to systematically review the literature to determine whether a staged or simultaneous approach to native nephrectomy in ADPKD is the optimal approach in terms of morbidity and graft outcomes.MethodsA literature search of MEDLINE and EMBASE was conducted to identify published systematic reviews, randomized control trials, case-controlled studies and case studies. Data comparing outcomes of staged and simultaneous nephrectomy for patients undergoing kidney transplantation was extracted and analyzed. The main outcomes analyzed were length of hospitalization, blood loss, operative time, other early postoperative complications and risk of graft thrombosis. Meta-analysis was conducted where appropriate.ResultsSeven retrospective cohort studies were included in the review. There was a total of 385 patients included in the analysis, of whom 273 patients underwent simultaneous native nephrectomy and kidney transplantation. Meta-analysis showed an increased cumulative operative time in staged procedures (RR 1.86；95% CI 0.43–3.29 p = 0.01) and increased risk of blood transfusions (RR 2.69; 95% CI 1.92–3.46 p < 0.00001). For the transplant procedure, there were no significant difference in the length of stay (RR 1.03; 95% CI -2.01-4.14 p = 0.52), major postoperative complications (RR 0.02; 95% CI -0.15-0.10 p = 0.74) and vascular thromboses (RR 1.42 95% CI 0.23–8.59 p = 0.7).ConclusionThe results suggest that staged nephrectomy followed by kidney transplantation is associated with a longer cumulative operative time and increased cumulative risk of blood transfusions. There is no evidence to suggest that performing a simultaneous nephrectomy and kidney transplant procedure increases the perioperative mortality rate, major postoperative complication rates or risk of vascular thrombosis.
