Renal arterial pseudoaneurysm after robotic-assisted partial nephrectomy: a single-center analysis.
Article in World journal of urology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo determine the incidence of renal artery pseudoaneurysm (RAP) after robotic-assisted partial nephrectomy (RaPN), identify predictive factors, and evaluate endovascular management.
methodsThe institutional RaPN database was retrospectively reviewed, and data from December 2009 to June 2021 were used. Computed tomography angiography was used to diagnose RAP. Patients who underwent embolization for RAP after RaPN were compared with those without RAP or with RAP managed conservatively. Data on patient demographics, tumor characteristics, and operative outcomes were evaluated, and the predictive factors for RAP after RaPN were determined.
resultsOf the 544 patients who underwent RaPN, 14 developed RAP after surgery, of which 12 underwent embolization. Most patients experienced gross hematuria and were diagnosed using computed tomography angiography. No patient exhibited recurrent RAP during follow-up. The following was found for patients who underwent embolization for RAP: a higher proportion of men (91.7% vs. 59.4%, p = 0.024), higher RENAL nephrometry scores (median: 9.0 vs. 8.0, p = 0.02), longer operative times (mean: 349.6 vs. 283.7 min, p = 0.046), and longer postoperative hospital stays (median: 6.0 vs. 5.0 days, p = 0.031). The N score in the RENAL nephrometry score was significantly higher in the embolization group (p = 0.031) than in the nonembolization group. Univariate analysis revealed that RENAL nephrometry scores and total operative time were significant predictors of RAP occurrence.
conclusionThe occurrence of RAP was associated with higher RENAL nephrometry scores and longer operative times.
