Despite advances in surgical techniques, the surgical procedure itself is associated with a risk of postoperative complications, with an incidence rate of 5-25%. The aim of this retrospective analysis was to identify risk factors for surgical complications after kidney transplantation. MATERIAL AND METHODS The study included 283 patients who underwent kidney transplantation at our center over an 11-year period (2013-2023). Baseline characteristics of the recipients (age, sex, and type of donor) and factors influencing the development of surgical complications (type of induction therapy, diabetes mellitus, BK positivity) were recorded. Patients who developed a surgical complication (bleeding, lymphocele, ureteral stenosis) were identified and analyzed in relation to potential independent risk factors. RESULTS Surgical complications occurred in 15.8% of patients (n=45), with ureteral stenosis comprising 60% of all surgical complications. The average time to surgical complication onset ranged from 5.4 to 8.6 months. By using Cox proportional-hazard regression multivariate analysis, none of the parameters that were looked at were found to be independent risk factors for the development of surgical complications (endpoints: surgical complications itself, bleeding, ureteral stenosis, lymphocele/lymphorrhea). CONCLUSIONS Kidney transplantation significantly improves quality of life and survival in patients with end-stage kidney disease. Surgical complications remain a significant post-transplant challenge, with urological, vascular, and parietal complications being most common. While we found no independent risk factors among the parameters studied, minimizing these complications is essential to reduce the need for reinterventions and to improve outcomes.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e948531"},"PeriodicalIF":1.1,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12166661/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144257173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it has been suggested that donor-recipient race-matching could improve kidney transplant outcomes, findings of previous studies are inconsistent. Therefore, the objective of this study was to conduct a systematic review examining the relationship between Black and White donor-recipient race-matching and graft and patient survival in adult primary kidney transplant recipients. MATERIAL AND METHODS Ovid Medline and Embase literature searches were conducted from earliest index date through October 2024. The following data were extracted and summarized: study characteristics, patient population characteristics, and findings associated with graft and patient survival. Quality assessment and magnitude of effects were evaluated, and Grading of Recommendations Assessment, Development and Evaluation (GRADE) was used to determine evidence certainty. RESULTS Of 4676 citations, 7 studies met inclusion criteria. Two studies reported Black-Black donor-recipient pairings, 2 studies reported Black-White donor-recipient pairings, and 3 studies reported White-Black donor-recipient pairings were at significantly higher risk for graft failure than the reference group; however, effect magnitude was small. Studies found the relationship between race-matching and patient survival was not statistically significant. Per GRADE, evidence concerning graft and patient survival is of low certainty or quality. CONCLUSIONS Studies generally found no differences in patient survival, and although Black-Black, Black-White, and White-Black donor-recipient pairings were associated with decreased graft survival in some studies, effects were small and likely clinically irrelevant. Further investigation of modifiable factors influencing graft survival is needed.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e947720"},"PeriodicalIF":1.1,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12144921/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144207463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moderate steatosis (30-60%) is particularly problematic, often leading to donor exclusion and reducing the available donor pool. Preoperative interventions aiming to reduce hepatic fat content have emerged as a potential strategy, but data regarding their safety and efficacy remain limited. MATERIAL AND METHODS This retrospective, single-center study evaluated 34 living liver donors between June 2023 and August 2024. Fourteen donors received preoperative treatment for moderate hepatic steatosis, while 20 donors with mild or no steatosis served as controls. Pre- and post-treatment assessments included body mass index (BMI), liver fat assessment via computed tomography (CT), liver function tests, and perioperative outcomes. RESULTS Preoperative treatment significantly reduced hepatic fat content, with all treated donors achieving steatosis levels below 30% (P<0.001). BMI and GGT levels also decreased significantly after treatment (P=0.01 and P=0.04, respectively). Postoperative liver function, intensive care unit stay, and hospital discharge times were comparable between the treated and control groups (P>0.05). No donor experienced serious complications during the early postoperative period or the first year of follow-up. All donors maintained satisfactory graft and remnant liver function, and no treatment-related adverse events were observed. CONCLUSIONS Preoperative management of moderate hepatic steatosis in living liver donors is effective in reducing liver fat to acceptable levels without compromising donor safety. This approach offers a promising strategy to expand the LDLT donor pool. Further large-scale, multicenter studies with extended follow-up are necessary to validate these findings.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e947772"},"PeriodicalIF":1.1,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12125959/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the trajectory and potential classes of the prognostic nutritional index (PNI) in kidney transplant recipients using a latent class growth model (LCGM), and assessed their predictive role in renal allograft function. MATERIAL AND METHODS This retrospective study included 257 kidney transplant recipients who received treatment in a tertiary hospital in Anhui Province from January 2019 to November 2020. Their data were collected at each 4 timepoints: T0 (pre-surgery, using the results of the recipient's most recent laboratory test prior to transplant), T1, T2, and T3 (1, 6, and 12 months, respectively after transplant surgery). The LCGM was conducted using Mplus 8.4, and a multiple linear regression model was employed to examine the ability of PNI trajectory to predict renal allograft function. RESULTS Using LCGM, 2 classes of PNI patterns best fit the sample: the low PNI slow growth group (C1, n=122,47.5%) and the high PNI fast growth group (C2, n=135, 52.5%). The linear regression showed that being a woman and being in the high PNI fast growth group were negative predictors of a high creatinine level (B=-35.946, P<0.001; B=-15.147, P=0.023). CONCLUSIONS There were 2 trajectories of PNI in the sample, with lower creatinine values 1 year after transplantation in the high PNI fast growth class. The initial level and developmental rate of PNI can positively predict renal allograft function. PNI may serve as a prognostic marker for renal allograft function in kidney transplant recipients.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e947388"},"PeriodicalIF":1.1,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12103085/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

POAF has been associated with serious long-term outcomes such as thromboembolic events, stroke, heart failure, and even graft instability. MATERIAL AND METHODS We assessed potential clinical, biochemical, and ECG predictors of POAF in LT recipients between 2012 and 2024.The patients were divided into 2 groups: POAF and non-POAF (34.5%, n: 38 and 65.4, n: 72, respectively). RESULTS Basal characteristics and comorbidities of the 2 groups were similar. Patients in the POAF group had significantly higher heart rates (81.16±18.62 bpm vs 65.11±12.47 bpm, P<0.01) and longer maximal P-wave durations (169.47±20.41ms vs 145.06±33.99 ms, P<0.01). Maximal P-wave duration, PR interval, P-wave peak time in lead II (PWPT-II), QRS duration, and QTc interval were also significantly longer in the POAF group compared to the non-POAF group. With these consistent findings, we may consider that changes or abnormalities in P-wave indices are significant indicators of atrial conduction delay, even before the development of LA enlargement. CONCLUSIONS Our results are valuable in providing the prediction of POAF, which may be associated with major adverse outcomes such as mortality in LT recipients, using a simple and inexpensive tool like ECG. Such risks can be minimized by strategies such as optimization of beta-blocker therapy, fluid and electrolyte balance, and intraoperative temperature regulation.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e948243"},"PeriodicalIF":1.1,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12085100/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Portal flow modulation techniques, such as splenic artery ligation (SAL), have been used to avoid complications like small-for-size syndrome (SFSS). However, the effects of SAL on portal flow, splenic function, and hematologic outcomes remain underexplored. MATERIAL AND METHODS This retrospective study analyzed 60 LDLT recipients treated at a single center from January 2023 to December 2024. Thirty patients underwent SAL (SAL+) while 30 did not undergo SAL (SAL-). Data on demographic and clinical characteristics, portal flow dynamics, spleen volume, hematologic parameters, and postoperative complications were collected and analyzed using IBM SPSS 20.0. Statistical significance was set at P<0.05. RESULTS SAL significantly reduced portal flow from 3148±989 mL/min to 1949±830 mL/min (P<0.001), optimizing the portal flow/graft weight ratio. SAL also decreased splenic volume by 21% and alleviated thrombocytopenia, with postoperative platelet counts increasing 3.8-fold compared to preoperative levels (P<0.001). There were fewer complications in the SAL+ group, with significant reductions in biliary complications and improved graft function. No severe ischemic splenic changes or thromboembolic events were observed in the SAL+ group. CONCLUSIONS SAL is an effective strategy for portal flow modulation in LDLT, significantly reducing portal flow to optimal levels and improving hematologic outcomes. By preserving splenic function and minimizing complications, SAL is a safe and beneficial approach to managing SFSS and improving graft performance in LDLT patients.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e947760"},"PeriodicalIF":1.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12065420/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143961407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MATERIAL AND METHODS We performed a retrospective 20-year observational follow-up study subsequent to a prior prospective study to evaluate the long-term outcomes following ligation of the proximal left renal vein (LRV). Between October 2001 and January 2005, 44 liver cirrhosis patients underwent LDLT with LRV ligation. These patients were followed up until April 2024 or patient death. RESULTS Portal flow was significantly increased after LRV ligation. Renal function recovered uneventfully after LDLT in 40 patients. Eighteen patients died due to cancer recurrence (n=6), pneumonia (n=3), and other causes (n=9), thus 1-, 5-, 10-, and 20-year overall patient survival rates were 95.5%, 86.4%, 81.8%, and 59.1%, respectively. Solitary atrophy of the left kidney was not observed. SSRS was completely resolved in 20 patients, but the other 20 patients showed persistently identifiable SSRS of variable extents to date or at patient death. The LRV was reopened to make large SSRS in another 4 patients, in which retrograde transvenous obliteration was performed in 2 for variceal bleeding control and in another 2 for portal flow augmentation.

Currently, direct ligation of the SSRS is preferred, but LRV ligation still can be a good therapeutic option when direct access to SSRS is not feasible.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e947492"},"PeriodicalIF":1.1,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11992949/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
