First Prospective Multicenter Evaluation of Robotic-assisted Partial Nephrectomy Using the DEXTER Robotic Surgery System.
Article in European urology open science, 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
Background and objective: Robot-assisted partial nephrectomy (RAPN) is a standard treatment for small renal tumors due to its precision and nephron-sparing properties. The DEXTER Robotic Surgery System is an open, sterile, compact, three-arm multiport system. This study evaluated the intraoperative and early postoperative safety and clinical performance of DEXTER in RAPN. Methods: A prospective observational study was conducted at two hospitals in France. Seven surgeons performed surgeries using DEXTER. The primary endpoints were major complications (Clavien-Dindo grades III-V) and procedural success rate. The secondary endpoints included perioperative outcomes and 30-d follow-up assessment.Key findings and limitationsThirty-three patients with a median age of 70 yr (interquartile range [IQR] 60-74) and a body mass index of 26.2 kg/m Conclusions and clinical implications: RAPN with DEXTER is feasible, and the study supports its short-term safety, even during the initial cases. Further studies are needed to assess its long-term performance. Patient summary: This is a prospective, multicenter cohort study of patients who underwent robot-assisted partial nephrectomy with the DEXTER Robotic Surgery System. During the study, all procedures were completed successfully without any conversions to open or laparoscopic surgery. The results support the short-term safety and feasibility, and highlight the ease of implementation of DEXTER. Further studies are needed to assess its long-term performance.
