1 · What the graph read from it

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.

2 · The registry

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: Ureteropelvic junction obstruction (UPJO) in horseshoe kidney (HSK) is surgically challenging because of aberrant anatomy. Robot-assisted pyeloplasty may overcome some limitations of laparoscopy, but data on the Chinese-developed KangDuo (KD) robotic system in HSK are lacking. This study evaluated the surgical procedure and efficacy of KD robot-assisted pyeloplasty for UPJO in HSK. Methods: This retrospective study included 14 adult patients with HSK and UPJO who underwent KD robot-assisted dismembered pyeloplasty between March 2021 and December 2025. Seven procedures used KD-SR1000 and seven used KD-SR2000. Perioperative outcomes, complications, renal function, and follow-up data were analyzed. Results: All 14 procedures were completed successfully without conversion or intraoperative complications. Preoperatively, 12 patients (85.7%) presented with flank pain, 7 patients (50.0%) had concomitant renal calculi, and 5 patients (35.7%) required preoperative stent insertion. Mean operative time was 200.7 minutes, and median blood loss was 20 mL. One postoperative urinary tract infection (Clavien-Dindo II) occurred. Postoperatively, mean serum creatinine improved from 77.8±17.3 to 69.6±16.6 μmol/L, and mean eGFR improved from 93.8±14.9 to 104.1±13.2 mL/min/1.73 m Conclusions: KD robot-assisted pyeloplasty is safe and feasible for UPJO in HSK and provides satisfactory mid-term outcomes. Larger prospective comparative studies are warranted to confirm these findings and assess cost-effectiveness.
