A decreased waist area is a risk factor of recurrent nephrolithiasis after ureteroscopy for Nonobese female patients: a retrospective study from a regional referral hospital in Japan.
Article in BMC urology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundObesity and metabolic syndrome have been identified as risk factors for nephrolithiasis. Although dietary improvements and exercise effectively prevent cardiovascular disease, their impact on recurrent nephrolithiasis has not been well studied. We investigated the associations between changes in body shape and recurrent nephrolithiasis.
methodsPatients who underwent computed tomography (CT) twice at intervals of more than 12 months after retrograde ureteroscopy to treat upper urinary stones of the calcium component from January 2014 to December 2021 at our hospital were retrospectively included. The changes in waist area (WA) according to CT, age, sex, previous stone episodes, number of stones at surgery, residual stones after surgery, and body mass index (BMI) at surgery were compared with those of patients who experienced recurrence and those who did not experience recurrence via univariate and multivariate analyses.
resultsA total of 96 patients were included in this study, with 48 patients in the recurrence group and 48 patients in the nonrecurrence group. The median age was younger in the recurrence group than in the nonrecurrence group (61.5 versus 70.5 years). The median BMI was 23 in both the recurrence group and the nonrecurrence group. The rate of recurrence in female patients with a decreased WA was greater than that in those with an increased WA (n = 9/5 versus 4/16) (p = 0.0137). Age under 70 years and a decreased WA were significant risk factors for the recurrence of renal stones according to multivariate analysis (p < 0.05).
conclusionA decreased WA on CT images is a risk factor for recurrent nephrolithiasis after ureteroscopy, especially in nonobese female patients.
trial registrationTrial registration was not performed, and the number of clinical trials was not suitable because this was a retrospective observational study at a single institution. All participants were retrospectively registered, and the study was approved by the Institutional Review Board and Ethics Committee of the Faculty of Medicine, Saga Japan (number 2023-11-R-4) at the date of 2/02/2024.
