Do previous percutaneous renal procedures affect the outcome of ultrasound-guided PCNL? A study at a large-volume center.

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
Purpose: This study aimed to investigate the influence of previous percutaneous renal procedures on the outcome of ultrasound (US)-guided percutaneous nephrolithotomy (PCNL) in patients with upper urinary tract stones. Patients and methods: Patients with a history of percutaneous renal procedures (PCNL/renal nephrostomy) from July 2017 to June 2023 were enrolled in this study as Group 1 ( Results: The procedure was successful in all patients. The patients' basic characteristics (gender, age, BMI, and stone size) were similar between the two groups. Puncture time and access creation time were significantly longer in Group 1 than in Group 2 ( Conclusion: Ultrasound-guided PCNL is safe and effective for patients with prior PCNL history, demonstrating an acceptable SFR. However, these cases exhibited prolonged access creation time, increased operative duration, and required more surgical tracts compared to naive cases.
