The efficacy of star-like mapping incision on vesicourethral anastomotic stenosis after radical prostatectomy and cystectomy.
Observational study in World journal of urology, 2025. 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
purposeTo assess the efficacy of star-like internal urethrotomy on vesicourethral anastomotic stenosis (VUAS) and its impact on voiding and continence outcomes.
methodsThis observational study was conducted in two tertiary referral hospitals. 31 patients confirmed with VUAS after radical prostatectomy or cystectomy were included. A novel Star-like Incision Urethrotomy procedure focused on a shallow incision on scar tissue all around the anastomotic site was performed. The primary outcome was the procedure's impact on urinary voiding and continence, assessed using the International Prostate Symptom Score (IPSS) and the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF).
resultsParticipants had a mean age of 68.32 years, 27 (87%) with a history of radical prostatectomy and 4 (13%) with a history of radical cystectomy, who presented to our clinic with urinary obstructive symptoms. We performed Star-like incision on the anastomotic site using a ureteral catheter as a guide. During patient follow-up, significant improvements were observed in urinary flow and continence. At one month postoperatively, the mean IPSS score decreased from 26.58 to 13.39, and the ICIQ-SF score initially increased from 4.48 to 6.87 at first and then reduced to about 4. These improvements were sustained throughout the six regular follow-ups, with an IPSS score of 12.8 and an ICIQ-SF score of 3.6. Besides these improvements, 5 (16%) patients required repeated urethrotomy due to recurrence of stenosis.
conclusionEndoscopic treatment with Star-like incision for VUAS has promising outcomes compared to other endoscopic treatments.
