Vaginal Mesh Exposure After Single-Incision vs Full-Length Midurethral Sling Placement: A Retrospective Cohort Study.
Article in International urogynecology journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 and hypothesisMidurethral slings (MUS) are the standard surgical treatment for stress urinary incontinence, but real-world data comparing vaginal mesh exposure risk across sling types are limited. We hypothesized that sling type, single-incision versus full-length, would be independently associated with vaginal mesh exposure and postoperative complications.
methodsWe conducted a retrospective cohort study of 369 women who underwent MUS placement by a single fellowship-trained Urogynecology and Reconstructive Pelvic Surgeon at a tertiary care institution from 2017 to 2023. Sling types included Altis® or Solyx™ (single-incision) and Advantage Fit™ or Obtryx™ II (full-length). The primary outcome was vaginal mesh exposure per IUGA/ICS criteria. Secondary outcomes included temporary urinary retention and bladder perforation. Time-to-event analysis used Kaplan-Meier curves and Cox regression, adjusting for sling type, menopausal status, and smoking history. Post hoc analysis confirmed 77% power for Altis® vs all other sling types.
resultsVaginal mesh exposure occurred in 28 patients (7.6%). Single-incision slings had higher exposure rates than full-length slings (12.6% vs 4.1%, HR 4.64, 95% CI 2.04-10.53, p < 0.001), with Altis® showing the highest risk (13.8% vs Advantage Fit™ 2.5%; HR 4.92, 95% CI 2.17-11.12, p < 0.001). Pre/perimenopausal status was also associated with elevated risk compared with postmenopausal status. Temporary urinary retention was less common with Altis® than with Advantage Fit™ (8.5% vs 19.1%). Bladder perforations occurred only with full-length slings (15 patients, 4.1%).
conclusionsSingle-incision slings, particularly Altis®, were associated with a higher mesh exposure risk than full-length slings. This device-specific risk difference may inform surgical planning and patient counseling.
