Feasibility and Safety of Repeat Robot-Assisted Partial Nephrectomy for Ipsilateral Local Recurrence: A Case Series.

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
objectivesTo evaluate the feasibility, safety, and short-term oncological and functional outcomes of repeat robot-assisted partial nephrectomy (RAPN) for ipsilateral local recurrence of renal cell carcinoma after partial nephrectomy (PN) and describe the relevant surgical strategies.
methodsWe retrospectively evaluated eight consecutive patients who underwent repeat RAPN between April 2019 and January 2026. Patient characteristics, perioperative outcomes, renal function, pathological findings, and adhesion severity were analyzed. Intraoperative adhesions were graded as minor or severe based on the surgeon's assessment.
resultsEleven ipsilateral recurrent tumors were analyzed in eight patients. Repeat RAPN was successfully performed in all patients without conversion to open surgery or radical nephrectomy. The median operative time, warm ischemia time, and estimated blood loss were 157 min, 15 min, and 50 mL, respectively. No major (Clavien-Dindo grade ≥ III) complications occurred. All malignant tumors were pT1a with negative surgical margins. At the median follow-up of 17.5 months, no local recurrence or distant metastasis was observed. The median eGFR values at 1 and 3 months were 57.1 and 55.7 mL/min/1.73 m
conclusionsRepeat RAPN may be a feasible and safe salvage option for ipsilateral recurrence after PN, with acceptable early oncological and functional outcomes. Our findings suggest that anti-adhesion agent use during the initial PN may be associated with reduced adhesion-related difficulty during subsequent reoperations, although further validation is needed.
