Anterior Sphincter-sparing Suturing of the Vesicourethral Anastomosis During Robotic-assisted Laparoscopic Radical Prostatectomy.
Article in European urology open science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Continence is an important functional outcome after robotic-assisted laparoscopic radical prostatectomy (RARP), and modifications of the surgical technique may improve outcomes. Objective: To illustrate a novel RARP technique and to describe the observed continence outcomes. Design setting and participants: A retrospective study of men treated with RARP between 2017 and 2021 was conducted. Surgical procedure: During RARP, periprostatic structures are preserved, the intraprostatic urethra is partially spared, and the anterior anastomosis stitches involve the plexus structures but not the anterior urethra. Measurements: A descriptive analysis of the pathological, functional, and short-term oncological outcomes was performed. Results and limitations: Of 640 men, 448 (70%) with at least 1 yr of follow-up and a median age of 66 yr were included. The median operative time was 270 min and the prostatic volume 52 ml. The transurethral catheter was removed after a median of 3 d, and leakage of urine in the first 24 h after catheter removal was observed in 66/448 patients (15%). Positive surgical margins were reported in 104/448 (23%). Prostate-specific antigen persistence after prostatectomy was observed in 26/448 (6%). During a median follow-up of 2 yr (interquartile range 1-3 yr), the biochemical recurrence after prostatectomy was observed in 19/448 patients (4%). One year after prostatectomy, 406/448 patients (91%) were continent and required no pad at all, while 42/448 (9%) required at least one pad per day. Conclusions: Not stitching the anterior urethra is a novel technical modification and may improve continence outcomes. Patient summary: We describe a novel way to stitch the bladder neck to the urethra after removal of the prostate using a surgical robotic system. Our technique appeared safe, with promising urinary continence results.
