Can operator-controlled imaging reduce fluoroscopy time during flexible ureterorenoscopy?
Article in Central European journal of urology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Introduction: Fluoroscopy is routinely used during ureterorenoscopy. According to the 'As Low As Reasonably Achievable' (ALARA) principle, radiation exposure should be kept as low as reasonably achievable to decrease the risk of negative long-term effects of radiation for patients and medical staff. This study aims to assess if operator-controlled imaging during flexible ureterorenoscopy for nephrolithiasis could reduce fluoroscopy time when compared to radiographer-controlled imaging. Material and methods: This study was a bicentric, retrospective comparison between patients treated for nephrolithiasis with flexible ureterorenoscopy with either operator-controlled imaging or radiographer-controlled imaging. A total of 100 patients were included, 50 were treated with operator-controlled imaging and 50 with radiographer-controlled imaging. Patients undergoing flexible ureterorenoscopy with a total stone burden <20 mm and data on radiation exposure were included. Patient characteristics, stone characteristics, surgical details and fluoroscopy time were recorded for each patient and both groups were compared. Patient data were expressed as median. A 2-sided p-value <0.005 was considered statistically significant. Results: This study found no significant differences between both groups regarding the patient and stone characteristics. However, it found a significant shorter fluoroscopy time in the operator-controlled imaging group of 33.5 seconds (IQR 16.0-70.0) compared to 57.0 seconds (IQR 36.8-95.3) in the radiographer-controlled imaging group (p = 0.001). Conclusions: This study shows that operator-controlled imaging in flexible ureterorenoscopy could reduce fluoroscopy time when compared to radiographer-controlled imaging. Operator-controlled imaging might therefore allow urologists to perform ureterorenoscopy with greater independence while additionally reducing fluoroscopy time and its consequent negative effects for medical staff and patients.
