Robot-assisted versus open kidney transplantation in patients who previously underwent an open kidney transplant.
Article in World journal of urology, 2026. 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
INTRODUCTION AND
objectivesThe safety of robot-assisted kidney transplantation (RAKT) in patients with end-stage renal disease (ESRD) who underwent an open kidney transplantation (OKT) in the past is unknown. We tested the hypothesis that intraoperative and postoperative complication rates are similar between RAKT and OKT in this patient population. MATERIALS AND
methodsThis was a multicenter retrospective cohort study including 78 patients with ESRD who received RAKT or OKT from living donor between 2015 and 2023 in 7 European academic centers. All patients had received an OKT in the past. The primary outcome was to assess perioperative safety in terms of intra- and postoperative complications, described using the Clavien-Dindo classification. Secondary outcomes included dialysis-free survival (DFS), surgical reintervention-free survival (RFS) and renal function at discharge. Kaplan Meier estimates and log-rank test were used to compare DFS and RFS according to the surgical approach.
resultsAmong 78 patients who previously underwent OKT, 29 (37%) patients subsequently underwent RAKT and 49 (63%) OKT. Patients' baseline characteristics were comparable between groups. The site of transplantation was the left iliac fossa in 24 (83%) and 30 (61%) patients undergoing RAKT and OKT, respectively (p = 0.07). Cold ischemia time was shorter in the RAKT group (60 vs. 114 min, p = 0.005), as was total vascular anastomosis time (33 vs. 38 min, p = 0.01). Estimated blood loss, rewarming time and intraoperative complications were similar in both groups. Early and late postoperative complications were similar in RAKT and OKT (respectively: 17% vs. 33%, p = 0.1; and 14% vs. 10%, p = 0.7). Over a median follow-up of 42 (IQR: 20-74) months, DFS was similar between RAKT and OKT, whereas RFS was higher in the RAKT group (100% vs. 84%, p = 0.02). Main limitations are represented by patient selection and the small sample size.
conclusionsIn selected patients undergoing kidney re-transplantation after a previous OKT, RAKT appears to be technically feasible and provides perioperative outcomes comparable to the open approach. In this challenging surgical setting, RAKT may represent a valuable option in experienced centres.
