Selective by design: early adoption patterns of single-port off-clamp robotic partial nephrectomy in a high-volume center.

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
backgroundIntroduction of single-port (SP) technology into centers with a consolidated multi-port experience in robot-assisted partial nephrectomy (MP-RAPN) represents a conceptual shift rather than a natural transition. We analyzed the early institutional adoption of the SP platform, assessing its impact on case complexity, perioperative outcomes, and determinants of surgical selection within a purely off-clamp RAPN framework compared with the established MP standard. MATERIAL AND
methodsAll consecutive RAPN performed at our tertiary referral center between May 2024 and October 2025 were analyzed (n = 372). All procedures were performed using a standardized off-clamp technique, irrespective of tumor features. After SP platform introduction, cases were stratified as multi-port (MP, n = 294) or single-port (SP, n = 78). Baseline, anatomical, and perioperative variables were prospectively collected. Tumor complexity was graded using the RENAL score, and renal function was assessed through serial eGFR measurements. Continuous and categorical variables were analyzed with Mann-Whitney U and χ²/Fisher tests; SMD > 0.20 denoted clinical imbalance. Univariable and multivariable Firth logistic regression identified independent predictors of SP adoption.
resultsBaseline characteristics were similar (each p > 0.2), except for tumor size and RENAL score, which were lower in SP cases (2.8 vs. 4.1 cm; 6.4 vs. 7.8; each p < 0.001). Perioperative outcomes-including hemoglobin drop, transfusion rate, complications, and hospital stay-were equivalent (each p > 0.05). SP tumors showed higher Fuhrman 1 (20.5% vs. 4.9%, p = 0.008) and pT1a stage (78.8% vs. 52.9%, p = 0.003). A lower RENAL score (OR 0.64, p < 0.001) independently predicted SP selection (C-index = 0.77).
conclusionsIn a center routinely performing purely off-clamp RAPN, adoption of the single-port robotic platform proved technically feasible and oncologically safe, achieving perioperative and functional outcomes equivalent to the multi-port approach during its early institutional phase.
