1 · What the graph read from it

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.

2 · The registry

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

objectivesTo analyze functional outcomes and complication rates of artificial urinary sphincter (AUS) implantation in patients who had undergone buccal mucosa graft urethroplasty (BMGU) beforehand. PATIENTS AND

methodsThis prospectively maintained single-center database comprises data from 236 patients from 2009 to 2015 who underwent AUS implantation. A total of 17 patients after BMGU were available for analysis. Primary endpoints consisted of continence and complication rates. Continence was defined as no use of safety pads, social continence as < 2 pads per day. Stricture recurrence was defined as a decrease in uroflowmetry, a maximum flow rate < 10 ml/s or residual urine volume (> 100 ml). Kaplan-Meier analysis determined explantation-free survival.

resultsMedian follow-up was 24 months (interquartile range [IQR] 6-31 months). Indication for AUS implantation was severe urinary incontinence with a history of radical prostatectomy (RRP) in 8 (47.1%), trauma in 1 (5.9%) and TUR-P in 8 (47.1%) patients. Pelvic irradiation was reported in 13 (76.5%) cases. The median length of buccal mucosa graft for urethroplasty was 4 cm (3-5 cm). A double cuff was implanted in 14 patients (82.4%), 3 patients received a single cuff. Complete and social continence was achieved in 76.5% and 100% of the patients, respectively. There was no significant difference in complications and explantation-free survival (log-rank, p = 0.191) between patients who had undergone BMGU before AUS compared to patients with no history of BMGU.

conclusionsAccording to the prospective follow-up data in a homogenous cohort, AUS implantation seems to be a viable, safe and effective therapeutic strategy for incontinence treatment despite previous BMGU.
