The selection process for kidney transplantation versus dialysis reflects complex clinical decision-making that has not been systematically characterized. Methods: This retrospective observational study analyzed all lung transplant recipients who developed ESRD at our center from 2010 to 2024 (n=32), comparing those receiving kidney transplantation (n = 18) versus those remaining on dialysis (n = 14). We developed an exploratory Clinical Selection Score to retrospectively characterize observed selection patterns and calculated E-values to assess robustness to unmeasured confounding. Results: Kidney transplant recipients were younger (35.7 \u00b1 12.9 vs. 48.4 \u00b1 14.8 years, p = 0.013) with better selection characteristics quantified by our Clinical Selection Score (4.1 \u00b1 0.8 vs. 1.6 \u00b1 1.1 points, p &lt; 0.001). The score showed excellent discrimination (C-statistic 0.82). Living donors were available for 88.9% of transplanted patients versus 0% of dialysis patients. In our selected cohorts, mortality was 22.2% in kidney transplant recipients vs. 78.6% in dialysis patients (p = 0.002), with median survival of 161.6 vs. 126.6 months (p = 0.021). After adjustment for age, kidney transplantation was observed to be associated with 72% lower mortality risk (HR 0.28, 95% CI 0.09\u20130.89, p = 0.031), though selection bias limits causal interpretation. The E-value of 6.61 suggests robustness to unmeasured confounding. Conclusions: This observational study describes real-world selection patterns and their associated outcomes in lung transplant recipients with ESRD. While carefully selected patients receiving kidney transplantation experienced favorable results, many patients were appropriately managed with dialysis based on medical and non-medical factors. Our analysis provides transparency about selection criteria and outcomes to inform clinical decision-making. Larger multicenter studies are needed to validate these findings and develop prediction tools.<\/jats:p>","DOI":"10.3390\/jcm14197017","type":"journal-article","created":{"date-parts":[[2025,10,3]],"date-time":"2025-10-03T14:18:28Z","timestamp":1759501108000},"page":"7017","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Selection Patterns and Outcomes of Kidney Transplantation Versus Dialysis in Lung Recipients with End-Stage Renal Disease: A Single-Center Retrospective-Observational Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9754-5028","authenticated-orcid":false,"given":"Fahim","family":"Kanani","sequence":"first","affiliation":[{"name":"Department of Transplantation, Beilinson Medical Centre, Gray Faculty of Medicine, Tel Aviv University, Petah Tiqwa 4941492, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mordechai","family":"R.
