Investigation of Triamcinolone Instillation in the Long-term Rate of Anterior Urethral Strictures' Recurrence.
Article in Current urology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers.
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
BACKGROUND/
aimsPrevious publications confirmed that after internal urethrotomy success rates in the short-term (less than 6 months) are varied (70-80%) and in the long-term results are generally low. In this study, the efficacy of triamcinolone instillation based on a newly introduced protocol on the rate of recurrence in patients with anterior urethral strictures was evaluated.
methodsA total of 66 patients were divided into treatment group (n = 33), in which triamcinolone was instilled on urethra after removing of Foley catheter and control group (n = 33) that not received any intervention. Each 40 mg/1 ml of triamcinolone vial was dissolved in 9 ml of distilled water and then a 2 ml of diluted solution was used for each instillation and 8 ml was kept in 4°C. Triamcinolone was instilled based on daily in week 1, every other day for week 2 and then every Monday and Friday for 2 months. Penile clamp was used after instillation for 1 hour. Treatment failure was based on urine flow rate, rate of recurrence and time to appearance of recurrence.
resultsThere were not any significant differences regrading to age (p = 0.09), length (p = 0.41) and diameter (p = 0.36) of stricture between 2 groups. Time to appearance of recurrence showed significantly in the treatment group when compared with that in the control group (1,350 ± 900 vs. 124.3 ±112 days; p < 0.01). In the treatment group, 88% had reasonable consequence, while in control 48%. There were 3 patients with a mean length-diameter of stricture around 0.3-5 cm who showed recurrence free with the mean of 720 days after intervention.
conclusionAdministration of triamcinolone instillation in urethra is associated with a decreased risk of stricture recurrence. Superior outcomes were seen in patients with a stricture length of more than 2 cm and this may in part reflect the increasing efficacy of the instillation method in the management of urethral strictures. These findings help identify patients with aggressive features of strictures in urethra who may benefit from intensified treatment efficacy of triamcinolone instillation.
