A Novel Technique of Traction Pre-Bladder Suturing in Single-Position Robot-Assisted Nephroureterectomy: Simplifying the Management of the Intramural Ureter.
Article in The international journal of medical robotics + computer assisted surgery : MRCAS, 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
objectiveTo evaluate the feasibility and preliminary perioperative outcomes of a traction pre-bladder suturing technique for managing the intramural ureter during single-position robot-assisted laparoscopic nephroureterectomy (RALNU) in patients with early-stage upper tract urothelial carcinoma (UTUC).
methods10 consecutive patients with early-stage UTUC underwent RALNU (Oct 2022-Aug 2023). The technique involves four steps: mucosal tenting, a purse-string suture for containment, en bloc resection of the protruding mucosa and ureter, and reinforced double-layer bladder closure.
resultsAll procedures were successful. Mean operative time was 145 min, with 38 min dedicated to the intramural segment. Mean blood loss was 35 mL, with no conversions or major complications. Pathology confirmed R0 resection of low-grade noninvasive carcinoma. Two metachronous bladder recurrences occurred during a median 12-month follow-up.
conclusionThis technique appears to be a feasible approach in patients with early-stage UTUC, with the potential to minimise urine spillage and facilitate secure bladder closure during RALNU.
