Robotic Vessel Sealer vs. Robotic Bipolar Grasper in Partial Nephrectomy.
Article in Cancers, 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
backgroundRobotic-assisted partial nephrectomy (RAPN) is widely used for nephron-sparing surgery. Vessel sealing technologies play a crucial role in these procedures, influencing ischemia time, blood loss, and surgical outcomes. This study compares the efficacy and safety of using a robotic vessel sealer (VS) versus conventional bipolar energy in robotic partial nephrectomy.
methodsA retrospective analysis was conducted on patients (n = 112) undergoing RAPN using either a robotic VS or bipolar energy grasper between 2023 and 2025. Parameters analyzed included ischemia time, estimated blood loss (EBL), postoperative complications, and functional outcomes. Statistical comparisons were performed to assess differences in perioperative and postoperative metrics.
resultsThe vessel sealer (VS) group (n = 54) had significantly lower blood loss (40 mL vs. 132.5 mL,
conclusionsBoth techniques seem to be used for tumors of comparable size and complexity, suggesting no strong selection bias. Future research should prioritize randomized controlled trials assessing long-term renal function, cost-effectiveness, and potential refinements of robotic vessel sealing technology. A broader, multicenter analysis could provide further insight into optimal device selection for robotic partial nephrectomy.
