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

Objectives: To evaluate and compare surgical techniques for robot-assisted reconstruction of recurrent bladder neck stenosis (BNS). BNS following a simple prostatectomy represents a rare but challenging condition in operative urology. Various robotic reconstructive techniques have been described, showing differing success rates. This monocentric case series reports on three distinct robotic surgical approaches for managing recurrent BNS. Patients and methods: A retrospective analysis was conducted on patients undergoing robot-assisted surgical repair for recurrent BNS at our institution. Clinical data, including patient history, comorbidities (Charlson Comorbidity Index), surgical treatment, complications (Clavien-Dindo classification) and follow-up outcomes, were analysed. Results: A total of 27 patients underwent robotic bladder neck reconstruction for recurrent BNS. Twelve patients were treated with YV plasty, 12 with stricture resection and end-to-end anastomosis and 3 with reconstruction using a buccal mucosa graft (BMG). At a median follow-up of 18 months, therapy failure occurred in 9 patients (33.3%), with failure rates of 25.0% for YV plasty, 33.3% for stricture resection and 66.7% for BMG plasty. Nine patients (33.3%) experienced surgery-related complications, including 7 minor complications (5 in the stricture resection group, 1 in the YV plasty group and 1 in the BMG group) and 2 major complications (1 in the stricture resection group and 1 in the YV plasty group). De novo incontinence occurred in five patients (19.2%), all of whom had undergone stricture resection with end-to-end anastomosis. Conclusions: Recurrent BNS poses a significant surgical challenge. Based on our experience, BMG reconstruction demonstrated suboptimal outcomes, while stricture resection was associated with the highest complication rate and the most frequent occurrence of de novo incontinence. YV plasty, with its relatively low morbidity and minimally invasive nature, has become the preferred technique in our institution for managing this condition. Prospective studies with larger cohorts are warranted to confirm these findings and further refine surgical approaches.
