Objective: Paired-exchange kidney transplantation (PKD) has gained in importance because of the difficulty to obtain suitable organs. The aim of this study was to compare the biochemical and clinical parameters of PKT with those of living-related kidney transplantation (LD).
Method: We compared 272 PKD performed in 3 transplant centers with 1885 LD. The 2 groups were compared for graft and patient survivals, rejection episodes, serum creatinine levels, and other biochemical parameters.
Results: The median human leukocyte antigen, mismatch was similar: PKD, 4 (95% confidence interval [CI], 3-4) and LD; 3 (95% CI, 3-4; P = .1292). The mean creatinine level among the PKT group of 1.07 ± .37 was lower then the LD group 1.17 ± .56 (P = .0043), but after the second year it was lower in the LD group (1.39 ± 0.61 and 1.16 ± 0.43; P < .0001). The rates of patient death (PKT, 3.31% vs LD 3.58; P = .9603), graft loss (2.74% vs 2.71%; P = .8647) and acute rejection episodes (19.48% vs 19.36%; P = 0.9719), were similar between the 2 groups.
Conclusions: Paired donation expands the living donor pool and decreases the number of waiting list patients. It is cost effective according to ABO incompetible transplantation.

Ureteral stenosis is a frequent complication after kidney transplantation, causing significant morbidity and potential graft function impairment. Treatment options include conservative management, endourological procedures, surgical interventions and percutaneous nephrostomy (PCN). While PCN effectively relieves obstruction, it comes with its own complications.

Long-term survival after lung transplantation is limited due to chronic lung allograft dysfunction (CLAD), which encompasses two main phenotypes: bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS). Donor-derived cell-free DNA (dd-cfDNA) is a biomarker for (sub)clinical allograft injury and could be a tool for monitoring of lung allograft health across the (pre)clinical spectrum of CLAD. In this proof-of-concept study, we therefore assessed post-transplant plasma dd-cfDNA levels in 20 CLAD patients (11 BOS and 9 RAS) at three consecutive time points free from concurrent infection or acute rejection, during stable condition, preclinical CLAD, and established CLAD ( = 3 × 20 samples).

PyVAN and PyVHC occurs in immunosuppressed (e.

Background: Proteinuria is associated with worse allograft outcomes in kidney transplant recipients (KTRs) and treatment strategies are limited. We examined the outcomes of calcineurin inhibitor (CNI) to belatacept conversion in proteinuric KTRs.
Methods: In a pilot phase II single-arm multicenter prospective trial, we recruited adult KTRs >6 months post-kidney transplantation with an estimated glomerular filtration rate (eGFR) ≥30 ml/min/1.

Background: We aimed to assess the rates of urethral stricture in transplant recipients, analyse patients with urethral strictures and present the posttreatment follow-up outcomes.
Methods: Between 2004 and 2023, a retrospective examination was conducted on kidney transplant recipients who underwent removal of ureteral catheters through retrograde cystoscopy at our facility or referred from external centres. The collected data encompassed patient demographics, pre- and posttransplant maximum urinary flow rate, specifics of stenosis, surgical interventions and outcomes from a 1-year follow-up.
