Machine Perfusion as a Temporal and Resuscitative Bridge in Emergent Renal Autotransplantation: A Novel Case Report.

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
BACKGROUND Renal autotransplantation is a well-described but infrequently used alternative to nephrectomy, complex renal or ureteral reconstruction, and allograft transplantation. While commonly performed and reported in the elective setting, it can be limited by ischemia, hemodynamic stability, and operative timing. Its use in the emergent setting can be limited by the patient's clinical stability and by the inability to safely perform immediate reimplantation. Hypothermic machine perfusion has been well described as a tool to improve outcomes following deceased donor transplantation. However, the role of hypothermic machine perfusion in autologous transplantation has not been clearly defined. CASE REPORT We describe a novel case of emergent renal explantation in a 56-year-old woman followed by delayed autotransplantation after a period of hypothermic machine perfusion. Reimplantation was performed following resuscitation and stabilization of the patient. After a period of postoperative delayed graft function, the patient experienced recovery of her native renal function and was ultimately able to discontinue hemodialysis. CONCLUSIONS This case demonstrates the safety and viability of renal autotransplantation following preservation with hypothermic machine perfusion. Machine perfusion can function as a temporal bridge in emergent situations when immediate reimplantation is unsafe, expanding the indications for organ preservation beyond deceased donation. This approach enables staged reconstruction in patients who may otherwise not be appropriate transplant candidates.
