Donor-gifted nephrolithiasis: case-based analysis and comparative study.
Article in The Canadian journal of urology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesDonor-gifted nephrolithiasis-the presence of a stone in a donor kidney at the time of transplantation-is rare. Research is limited, and no consensus high-quality evidence guidelines exist, leaving selection criteria and management to individual provider discretion. We aimed to estimate the frequency and analyze patient and graft outcomes of deceased donor (DD) transplant recipients with stones in their kidneys at Wake Forest Baptist Medical Center.
methodsAll DD renal transplants or patients receiving most of their care postoperatively after DD renal transplantation at our institution from 1979 to 2025 were reviewed. Stones were considered donor-gifted if discovered during transplantation or on imaging within two weeks of the transplant date. Patient, stone, and graft outcomes were followed over time. Stone size on imaging was compared between patients who were treated versus surveyed for their donor-gifted stones using an independent samples t-test.
resultsOf 4723 patients who underwent DD renal transplant, eight were found to have a graft with stones at transplant (0.2%). The median stone size was 8 mm. Three (38%) patients underwent treatment for stones, and five (62%) underwent surveillance. Two (25%) patients experienced graft failure, and one of these patients received stone treatment.
conclusionsThe frequency of donor-gifted nephrolithiasis is extremely low in DD transplant patients. Despite a small sample set, these results demonstrate favorable outcomes and provide support for the feasibility of intentionally performing DD renal transplantation in grafts with known stones.
