5G remote-controlled snake-arm single-port robotic pneumovesical Cohen ureteroneocystostomy: first animal study.
Article in Frontiers in pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: To explore the initial technical feasibility of 5G remote-controlled single-port robotic-assisted pneumovesical ureteroneocystostomy (Cohen procedure) in an animal model, and to provide preliminary experimental evidence for this integrated surgical approach. Methods: A healthy female juvenile Landrace crossbred pig (3-4 months old, 32 kg) was used as the experimental model. The procedure was performed at the Animal Experimental Center of Surgerii Robotics Co., Ltd., with remote control via 5G network from Fujian Children's Hospital. A snake-arm single-port robotic system was utilized to perform pneumovesical ureteroneocystostomy (Cohen procedure). Technical feasibility and parameters were evaluated. Results: The surgery was successfully completed with total operative time of 92 min and blood loss of 6 mL. The 5G network maintained stable video transmission and real-time control throughout the procedure. No major intraoperative complications occurred, and the animal recovered uneventfully during the 24-hour observation period. Anatomical examination confirmed accurate ureteral reimplantation, patent anastomosis, and absence of urinary extravasation. Conclusions: This study successfully implemented 5G remote-controlled snake-arm single-port robotic-assisted pneumovesical ureteroneocystostomy (Cohen procedure) in an experimental animal model for the first time. The single-case piglet model demonstrated the initial technical feasibility and provided a proof-of-concept for its procedural feasibility under experimental conditions. It provides important technical support for minimally invasive treatment of vesicoureteral reflux in children, with promising potential for future research.
