Safety and effectiveness of robot-assisted partial nephrectomy in ambulatory mode: a single-center retrospective cohort study.
Article in Journal of robotic surgery, 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
To compare short-term outcomes and resource use between ambulatory and conventional inpatient robot-assisted partial nephrectomy (RAPN). This single-center retrospective cohort included 143 consecutive adults with localized renal tumors who underwent RAPN from June 2021 to December 2024. The ambulatory group (n = 75) followed a standardized pathway with planned discharge within 48 h and structured post-discharge nursing follow-up; the conventional inpatient group comprised 68 patients. Perioperative recovery, hospital resource use, renal function, and 30-day safety outcomes were compared. Baseline, tumor, operative, and renal-function measures did not differ significantly between groups. The ambulatory group had shorter drainage-tube duration, earlier ambulation, oral intake, catheter removal, and return to normal activity, shorter hospital stay [29.0 (27.5-30.5) vs. 87.5 (80.8-99.0) h], and lower hospitalization cost [45,860 (44,876 - 46,806) vs. 62,096 (60,452 - 63,862) CNY] (all P < 0.001). Planned discharge was completed by 67 of 75 ambulatory patients (89.3%); 8 (10.7%) had delayed discharge. No statistically significant between-group differences were detected in transfusion, positive margins, readmission, reoperation, 30-day complications, wound infection, or eGFR through 3 months. The ambulatory group had more follow-up calls and messages within 7 days (both P < 0.001). In selected patients at an experienced center, ambulatory RAPN was associated with shorter hospitalization, lower in-hospital cost, and earlier recovery without a statistically detectable increase in short-term adverse outcomes. The retrospective single-center design and low event counts preclude causal or equivalence conclusions.
