Impact of fluoroscopy technique on radiation time and surgical outcomes in supine percutaneous nephrolithotomy: a propensity score-matched analysis of intermittent versus live fluoroscopy.

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
purposeFluoroscopy is commonly used during Percutaneous Nephrolithotomy (PCNL) for renal access and tract dilatation; however, it is associated with radiation exposure for both patients and surgical staff. Strategies to minimize exposure include reducing fluoroscopy time, which serves as a surrogate marker of radiation dose. This study aims to examine the effect of reducing fluoroscopy time using intermittent fluoroscopy on treatment and perioperative outcomes in supine PCNL.
methodsWe retrospectively analyzed data from 446 patients who underwent supine PCNL between April 2021 and August 2025. After applying exclusion criteria, 392 patients were included. Two experienced surgeons performed or supervised the procedures, one utilizing intermittent fluoroscopy and the other live fluoroscopy. Baseline demographics, stone characteristics, operative variables, fluoroscopy time, stone-free rates (SFR), complications, and hospital stay were compared. Propensity score matching (PSM) was conducted to minimize group baseline differences.
resultsBefore matching, 310 patients underwent intermittent fluoroscopy, and 82 underwent live fluoroscopy. After PSM, 82 patients remained in each group with comparable demographics and stone characteristics. Median fluoroscopy time was significantly lower in the intermittent group (25.5 s [IQR: 18-35.25]) compared with the live group (267 s [IQR: 182.5-314]; p < 0.001). Stone-free rates were similar (79.3% vs. 81.7%; p = 0.694), as were operative time, hospital stay, and complication rates(all p > 0.05).
conclusionIntermittent fluoroscopy during supine PCNL substantially reduces fluoroscopy time without compromising stone-free rates, operative outcomes, or complication rates. This approach may be considered a safer alternative for minimizing radiation exposure to patients and healthcare providers.
