Impact of Narrow Anvil Stapler on Graft Vein Length in Right-sided Living-donor Nephrectomy.

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
Background: Right-sided living donor nephrectomy presents a challenge because of the shorter renal vein length, which may complicate vascular anastomosis during transplantation. We hypothesized that the use of a narrow anvil stapler could optimize vein preservation by allowing safer and more effective transection closer to the inferior vena cava. This study aimed to compare the effectiveness of the Signia Small Diameter Reload Short with Curved Tip (SDR) and the Tri-Staple 2.0 Reload (TSR) in preserving renal vein length and to evaluate their impact on donor and recipient outcomes. Methods: We conducted a retrospective observational cohort study of 39 right-sided donor nephrectomies performed at 2 institutions between May 2019 and December 2024. Patients were divided into 2 groups based on the stapler used: TSR (n = 16) and SDR (n = 23). Inverse probability of treatment weighting was applied to adjust for baseline differences, resulting in a final analysis of 11 TSR and 23 SDR cases. We evaluated renal vein length and overall surgical outcomes. Results: The SDR group had significantly longer renal vein lengths than the TSR group (23.0 ± 4.0 versus 17.5 ± 3.9 mm, Conclusions: The SDR stapler provided a significant technical advantage in preserving renal vein length in right-sided donor nephrectomy. However, this did not translate into improved recipient outcomes, suggesting that surgical precision and vascular adaptation play a more critical role in transplantation success than vein length alone. Nonetheless, the ability to preserve greater vein length remains a potential advantage, particularly in challenging cases.
