Substitution urethroplasty for posterior urethral stenosis.

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
Posterior urethral stenosis occurs commonly following traumatic urethral injury, treatment for prostatomegaly or prostate cancer, and pelvic radiation. Perineal reconstruction for posterior urethral stenosis can be performed via excisional urethroplasty with primary anastomosis, or via substitution urethroplasty with the use of buccal mucosa graft (BMG). This article provides a stepwise description and comprehensive review of our technique for posterior substitution urethroplasty. Helpful tips and recommendations regarding common pitfalls encountered perioperatively are also presented. Key maneuvers described include unilateral urethral mobilization, graft fixation using laparoscopic suturing devices, fibrin sealant, or a barbed-suture sewing machine, as well as the use of the RaViNi lighted urethral speculum to enhance urethral exposure. In addition to describing our technique and institutional outcomes, a brief and focused review of the literature is presented to support the utility of substitution urethroplasty in posterior urethral reconstruction. While there is a dearth of prospective data, retrospective studies from single-center and multi-institutional data report success rates for posterior substitution urethroplasty between 63% and 89%, with rates of
