Renal vascular patterns assessment before robot-assisted partial nephrectomy: a video-based correlation with hilum dissection.
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
purposeSurgical video review (SVR) is an emerging tool for assessing patient outcomes, especially in complex surgeries such as robot-assisted partial nephrectomy (RAPN). Adhesive probability and morphological scores are used to evaluate fat management and warm ischemia, respectively; however, the factors influencing renal hilum control (RHC) during RAPN have not yet been assessed. The aim of this study is to use SVR to identify the renal vascular patterns and factors that influence RHC.
methodsWe evaluated 60 surgical video recordings of patients undergoing RAPN in 2023-2024, and measured the time to hilum control (THC) and total operation time (TOT) using a stopwatch. Patient and surgical factors were recorded and SPSS software was used to identify the correlation of these factors and vascular patterns with THC.
resultsWe observed a median THC of 22.7 min representing 15.1% of TOT. A significant correlation was found between previous renal surgery (p = 0.033), complex vascular anatomy on the right side (artery bifurcation behind IVC) or left side (more than one artery) (p = 0.02) and a longer THC. No significant difference was found between surgeons (p = 0.753) or surgical approach (transperitoneal vs. retroperitoneal, p = 0.87).
conclusionTHC represents a relatively short part of the total RAPN time. Previous renal surgery and a complex vascular pattern with artery bifurcation behind IVC on the right side and more than one main renal artery on the left side, can lead to longer THC. A detailed understanding of renal vascular patterns can provide a patient-specific surgical planning and optimise strategies for RAPN.
