Anatomy of urethro-vesical segment and vaginal microbiota: is there any connection at stress urinary incontinence?
Article in Frontiers in medicine, 2026. 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
Background: Stress urinary incontinence (SUI) is one of the most prevalent pelvic floor disorders in women. While previous studies have demonstrated associations between urinary incontinence and changes in vaginal microbial composition, the relationship between vaginal microbiota and anatomical characteristics of the lower urinary tract remains insufficiently investigated. Objective: To evaluate the association between vaginal microbiota composition and sonographic parameters of the urethrovesical segment in women with SUI before and after surgery. Methods: This study included 100 women with SUI. Ultrasound assessment included measurements of urethral length and diameter, bladder neck mobility, Results: Prior to surgery, 238 microbial strains representing 49 species were isolated. Gram-positive microorganisms predominated, with Staphylococcus spp. (32.8%), Enterococcus spp. (19.8%), and Lactobacillus spp. (13.0%) being the most common taxa. Following surgery, the proportion of Lactobacillus spp. increased significantly from 13.0% to 33.5% ( Conclusions: Surgical treatment of SUI is associated with significant symptom improvement and early changes in the structure of the cultivable vaginal microbiota, including an increased representation of Lactobacillus spp. The observed associations between characteristics of the vaginal microbiota and sonographic parameters of the urethrovesical segment suggest a possible relationship between the anatomical and functional characteristics of the lower urinary tract and the local microbial environment. However, the nature of these associations and their causal direction remain undetermined. The findings should therefore be considered hypothesis-generating and require confirmation in prospective studies with a control group, longer follow-up, and the use of modern microbiome profiling methods.
