Interrupted vs. continuous suture urethroplasty in tubularised incised plate hypospadias: an updated systematic review & meta-analysis.

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
purposeThe optimal suturing technique for urethral tubularisation during tubularised incised plate (TIP) urethroplasty remains debated. This systematic review and meta-analysis compared perioperative and postoperative outcomes of interrupted versus continuous suturing techniques in paediatric hypospadias repair.
methodsA systematic literature search was performed in PubMed, Cochrane Library, Embase, Scopus, and ClinicalTrials.gov from inception to December 2025 in accordance with PRISMA guidelines. Randomised controlled trials and observational studies comparing interrupted and continuous suturing during paediatric TIP urethroplasty were included. Outcomes assessed were urethrocutaneous fistula, surgical site infection, meatal stenosis, urethral stricture, glans dehiscence, overall complications, urinary stream outcomes, operative time, and reoperation rates. Risk of bias was evaluated using the Cochrane Risk of Bias 2.0 tool and the ROBINS-I. A random-effects meta-analysis supplemented by influence diagnostics and Hartung-Knapp adjustment for heterogeneous outcomes, were conducted using R version 4.5.2, with results expressed as odds ratios (ORs) or mean differences (MDs) and corresponding 95% confidence intervals (CIs).
resultsFifteen studies involving 2625 paediatric patients were included, with 800 undergoing interrupted suturing and 1,825 continuous suturing. No statistically significant differences were observed between techniques for urethrocutaneous fistula (OR 0.65, 95% CI 0.38-1.11), surgical site infection (OR 0.61, 95% CI 0.25-1.48), meatal stenosis (OR 0.98, 95% CI 0.54-1.80), urethral stricture (OR 1.08, 95% CI 0.29-3.97), overall complications (OR 0.75, 95% CI 0.48-1.17), or glans dehiscence (OR 0.77, 95% CI 0.36-1.63). Operating time showed no clinically meaningful difference operative time (MD 3.77 min, 95% CI - 3.69 to 11.24, Hartung-Knapp adjusted).
conclusionContinuous and interrupted suturing techniques during TIP urethroplasty demonstrate comparable complication rates and functional outcomes. These findings suggest that suturing technique may be selected based on surgeon preference and experience; however, large, well-designed multicentre randomised trials are required to further inform clinical practice.
