In situ urethroplasty at the time of artificial urinary sphincter explantation for urethral erosion: an 18-year single-center experience.
Article in World journal of urology, 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
purposeWe evaluated the outcomes of immediate in situ urethroplasty performed at the time of artificial urinary sphincter explantation for urethral erosion and explored the factors associated with postoperative wound dehiscence. MATERIALS AND
methodsWe retrospectively reviewed patients who underwent artificial urinary sphincter explantation for endoscopically confirmed urethral cuff erosion at a single tertiary referral center between January 2008 and September 2025. Partial erosions were managed using primary repair, whereas circumferential defects were treated using excision and primary anastomosis. The primary outcome was the postoperative urethral stricture-free rate. Secondary outcomes included postoperative wound dehiscence and secondary artificial urinary sphincter implantation. Exploratory subgroup analyses were performed to compare the patients with and without postoperative wound dehiscence.
resultsSixteen patients were included in the study. The median patient age was 76 years, and the median follow-up duration was 14 months. Six patients (37.5%) had prior pelvic radiation therapy and seven (43.8%) had diabetes mellitus. Postoperative urethral stricture occurred in one patient (6.3%), yielding a stricture-free rate of 93.8%. Postoperative wound dehiscence occurred in seven patients (43.8%). All wounds were limited to the subcutaneous tissue and were managed with secondary closure under local anesthesia (Clavien-Dindo grade IIIa). Secondary artificial urinary sphincter implantation was performed in seven patients (43.8%), with two patients requiring repeat explantation due to recurrent infection.
conclusionsImmediate in situ urethroplasty at the time of artificial urinary sphincter explantation was associated with a low observed urethral stricture rate in this selected cohort, although interpretation is limited by the small sample size and absence of a comparator group.
