Survival Without Reintervention of Second Artificial Urinary Sphincter Implants in Men: A National Healthcare Data System-Based Study in France.

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
purposeArtificial urinary sphincter (AUS) is the gold standard treatment for severe male stress urinary incontinence (SUI). While survival outcomes after primary implantation are now well established, the prognosis following reintervention remains poorly understood. We aimed to assess long-term reintervention-free survival after a second AUS implantation and to compare outcomes between device replacement and reimplantation after removal. MATERIALS AND
methodsWe performed a nationwide, population-based, retrospective cohort study including all men aged ≥18 years in France who underwent a second AUS implantation between 2006 and 2018 for SUI following prostate cancer or benign prostatic hyperplasia treatment. AUS procedures were identified through a unique device identifier. Of 5,132,311 eligible men, 8,475 received a first AUS and 1,619 a second AUS: 1,165 after device replacement and 454 after reimplantation following removal. The primary outcome was reintervention-free survival, estimated by Kaplan-Meier analysis. Secondary outcomes included replacement and removal rates. Predictors of reintervention were identified using multivariable Cox regression.
resultsMedian follow-up was 53 months (IQR 26-81). Reintervention-free survival after second AUS was 81% (95% CI 79-83) at 2 years, 68% (95% CI 65-71) at 5 years, and 61% (95% CI 57-64) at 10 years. Device replacement achieved significantly better survival than reimplantation after removal (p <0.001). Notably, only 21% of patients whose first AUS was removed underwent reimplantation.
conclusionsSecond AUS implantation provides durable long-term outcomes, approaching those of primary implants. The indication for reintervention critically influences prognosis, with replacement outperforming reimplantation after removal. The low reimplantation rate after AUS removal provides a clinically relevant piece of information to counsel patients requiring device removal.
