Extraperitoneal Robot-Assisted Radical Prostatectomy Using Hinotori™ Surgical Robot System: Report of First Series of Seven Cases.
Article in Cureus, 2025. 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
objectivesThe Hinotori™ surgical robot system (HSRS) (Medicaroid, Kobe, Japan), a newly launched domestic platform in Japan, has already been utilized in many robot-assisted surgeries. This study aimed to assess the perioperative outcomes of the first series of seven cases that underwent robot-assisted radical prostatectomy (RARP) with an extraperitoneal approach (EP) using HSRS.
methodsA total of seven consecutive patients with localized prostate cancer who underwent RARP with EP using the HSRS between January and May 2025 at our institution were included in this study. Their comprehensive perioperative outcomes were retrospectively analyzed.
resultsThe median age and the body mass index (BMI) of the patients were 69 years and 21.9 kg/m², respectively. RARP with EP could be completely performed on all patients without conversion to either a transperitoneal approach or open surgery. The median operative time, the time using the robotic system, the estimated blood loss, and the length of the indwelling urethral catheter were 180 min, 96 min, 100 mL, and seven days, respectively. No patient experienced major perioperative complications requiring invasive treatment or blood transfusion.
conclusionsDespite being a small case series, this is the first report of the perioperative finding that RARP with EP using the HSRS is expected to provide equivalent perioperative outcomes compared to RARP with transperitoneal (TP).
