Impact of preoperative double-J stent placement on stone recurrence following flexible ureteroscopic lithotripsy.

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
ObjectiveThis study investigated the effect of preoperative double-J stent placement on stone recurrence following flexible ureteroscopic lithotripsy and analyzed the risk factors for postoperative stone recurrence. The study aimed to provide a clinical reference for better management of the identified risk factors.MethodsThis retrospective study collected data from patients who underwent flexible ureteroscopic lithotripsy for urinary stones between April 2023 and May 2024. Patients were divided into two groups based on whether a double-J stent was placed preoperatively. Comparisons were made between the stent and nonstent groups. Univariate and multivariate logistic regression analyses were performed to identify the risk factors for postoperative stone recurrence.ResultsThe recurrence rate was 19.51% in the nonstent group and 1.47% in the stent group, with a statistically significant difference (P = 0.001). Stone removal strategy (P < 0.001), preoperative systolic blood pressure (P = 0.017), and intraoperative blood loss (P = 0.044) were identified as risk factors for postoperative recurrence, with stone removal strategy (P = 0.013) and preoperative systolic blood pressure (P = 0.017) being independent risk factors.ConclusionsPreoperative placement of a double-J stent is associated with a lower recurrence rate of stones following flexible ureteroscopic lithotripsy than no preoperative stenting. Stone removal strategy and preoperative systolic blood pressure are independent risk factors for stone recurrence following flexible ureteroscopic lithotripsy.
