Non-transecting dorsal mucosal anastomosis plus ventral oral graft for the treatment of urethral bulbar strictures: single surgeon experience.

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
purposeTo report our experience with the non-transecting dorsal mucosal anastomosis plus ventral oral graft urethroplasty (NTAVOG) for the repair of tight bulbar urethral strictures.
methodsData of 68 men with tight bulbar strictures underwent NTAVOG urethroplasty between 2012 and 2019 were retrospectively revised. The urethra was opened ventrally; the dorsal scarred mucosa was excised preserving the spongiosum; the mobilized mucosal edges were anastomosed to recreate the dorsal urethral plate; the repaired urethral plate was augmented by the ventral oral graft and the spongiosum was closed over it. Successful urethral reconstruction was defined as normal voiding without the need for any postoperative procedure. Sexual function was investigated using a validated questionnaire.
resultsMedian follow-up was 58 months (IQR 38-63) and mean stricture length was 1 cm (IQR 1-1.5). Of 68 cases, 56 (82.4%) were successful and 12 (17.6%) were failures requiring re-treatment. At multivariable analysis, no preoperative factor was significantly associated with recurrence. None of the preoperatively sexually active 53 patients reported postoperative erectile impairment and all were satisfied with their sexual life. The main limitation is the retrospective design.
conclusionsIn cases of tight bulbar stricture, the NTAVOG urethroplasty provides adequate urethral augmentation by preserving the spongiosum and avoiding postoperative sexual complications. We presented a series of patients undergone non-transecting dorsal anastomosis plus ventral oral graft urethroplasty for tight bulbar stricture. This treatment seems to be safe and with limited postoperative complications thanks to the preservation of the corpus spongiosum.
