Patient satisfaction and feasibility with a novel drug-injectable urethral catheter set for hyaluronic acid administration: a multicenter randomized trial.
Trial report in Scientific reports, 2025. 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
Reducing the risk of urethral strictures after transurethral surgery for patients with bladder cancer requires effective strategies. We compared the clinical outcomes of a novel drug-injectable urethral catheter set (NIUS) with hyaluronic acid (HA) with those of the conventional intraurethral HA injection method. This six-center, prospective, randomized, single-blind trial included 192 male patients aged ≥ 20 years scheduled to undergo transurethral surgery. The primary outcome was patient-reported satisfaction. Secondary outcomes were patient-reported pain intensity, clinician-reported convenience, and urethral strictures. Cystourethroscopy was performed under direct visualization. Outcomes of the experimental (NIUS with HA) and control (HA) groups were compared using the chi-square test and t-test. The post-transurethral surgery rate was significantly higher in the experimental group than in the control group (p < 0.001). Overall, 40% and 21.7% of patients in the experimental and control groups, respectively, were very satisfied (p < 0.001). The experimental group had lower postoperative pain intensity scores (p < 0.001), higher clinician-reported convenience scores (p < 0.001), and fewer urethral strictures within 3 months postoperatively (p < 0.001) than the control group. The NIUS with HA after transurethral surgery significantly enhanced patient satisfaction, reduced pain, improved clinician convenience, and was associated with a reduction in grade 1 urethral strictures. Thus, NIUS with HA enhances post-surgery outcomes through improved patient satisfaction and reduced urethral strictures.Trial registration: Cris.nih.go.kr (KCT0007010).
