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

introductionRadiation exposure during percutaneous nephrolithotomy (PCNL) can vary depending on the method used for renal access. This study aimed to compare fluoroscopy time and dose during PCNL when renal access is achieved via interventional radiology (IR) versus urology.

methodsA retrospective review of patients who underwent unilateral PCNL between January 2020 and February 2023 was conducted. Patients were categorized by renal access method: endoscopic combined intrarenal surgery performed by a urologist (ECIRS) or IR-assisted. A Wilcoxon rank-sum test and multivariate analyses were done to compare several parameters of the two groups.

results66 patients underwent ECIRS (group 1), and 31 underwent IR-assisted access (group 2). The groups were similar in age, BMI, sex, and stone size. The difference in medians for fluoroscopy dose, fluoroscopy time, operative time and length of stay were statistically significant (p < 0.001). Average fluoroscopy dose (39.6 vs. 327 mGy) and time (1.46 vs. 10.9 min), along with average operative time (1.97 vs. 3.00 h) and length of stay (1.26 vs 3.06 days) were all lower in group 1. In the IR group, a positive correlation was noted between BMI and fluoroscopy dose (p < 0.001), though this correlation was absent with ECIRS.

conclusionsPCNL with ECIRS access significantly reduces radiation exposure and operative time compared to IR-assisted access. Additionally, BMI influenced radiation exposure and operative time in the IR group, but not in the ECIRS group. Endoscopic renal access may lower overall radiation exposure and postoperative complications.
