Renal functional and surgical outcomes after robot-assisted partial nephrectomy for hilar
Article in World journal of nephrology, 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
backgroundRobot-assisted partial nephrectomy (RAPN) is well-suited for managing complex renal tumors, including those located in the renal hilum. However, studies directly comparing RAPN outcomes for hilar and non-hilar tumors, particularly in terms of comprehensive measures, such as trifecta and pentafecta, are still limited.
aimTo evaluate whether tumor location in the renal hilum independently influences surgical and renal functional outcomes after RAPN, as assessed by trifecta and pentafecta criteria.
methodsThis single-center retrospective cohort study evaluated outcomes of RAPN for hilar and non-hilar renal tumors treated from April 2016 to June 2023. Eligible patients had tumors ≤ 7 cm, no metastasis, and at least one year of follow-up. Propensity score matching was applied. Primary endpoints were trifecta and pentafecta achievement. All procedures were performed under ischemia without early unclamping. Multivariate logistic regression identified predictors of outcome achievement.
resultsOf 350 patients, 324 met the inclusion criteria, consisting of 60 hilar and 264 non-hilar tumors. Trifecta achievement was similar between hilar (63.3%) and non-hilar groups (64.0%), with no significant differences in ischemia time, positive margins, or major complications. Pentafecta achievement rates were also similar (20.0% hilar
conclusionRAPN achieved comparable trifecta and pentafecta outcomes for hilar and non-hilar tumors, supporting its viability for complex hilar tumors when appropriate patient selection and surgical experience are ensured.
