Near-Obliterative Bulbar Urethral Stricture 12 Years After Artificial Urinary Sphincter Implantation: A Case Report.
Article in IJU case reports, 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
Introduction: Artificial urinary sphincter implantation is guideline-supported for post-prostatectomy stress urinary incontinence; however, ultra-late urethral deterioration remains poorly characterized. Case Presentation: A 66-year-old man underwent radical retropubic prostatectomy in December 2006, followed by salvage radiotherapy in April 2007. Twelve years after artificial urinary sphincter implantation, intraluminal cuff exposure was incidentally detected on cystoscopy before urethral catheterization for orthopedic surgery. Urinalysis at diagnosis and pre-explant urine culture were unremarkable. Explantation was delayed for 5 months because of patient preference after counseling about infection and urethral injury risks. At explantation, the bulbar urethra showed near-obliterative circumferential collapse with loss of architecture, requiring excision and primary anastomosis urethroplasty (EPA). Obstructive symptoms recurred within 2 months, and recurrent stricture was confirmed endoscopically; suprapubic cystostomy was required at 3 months. Conclusion: This case demonstrates ultra-late advanced urethral deterioration beyond focal cuff erosion or simple atrophy. In high-risk radiated patients, explantation may not restore urethral integrity.
