Voiding cystourethrography for the pediatric nephrologist: clinical value, challenges, and areas of debate.
Review in Pediatric nephrology (Berlin, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Voiding cystourethrography (VCUG) is indicated for evaluating the anatomy of the urethra and bladder. It is primarily used to diagnose vesicoureteral reflux (VUR) and posterior urethral valves (PUV), especially in cases of febrile urinary tract infections (UTIs), significant ureteral dilation on ultrasound, and-in continent children-urinary symptoms suggestive of infravesical obstruction. VCUG exposes children to a non-negligible dose of radiation and requires urethral catheterization, which can be painful-particularly in males-and carries a low but present risk of post-procedural UTI. Despite its widespread use, VCUG can miss VUR in up to 50% of cases. Moreover, recent studies report that preoperative suspicion of PUV on VCUG was present in only 46% of non-toilet-trained and 59% of toilet-trained males, likely due to challenges in interpreting the VCUG findings. In this review, we will highlight the clinical value, challenges, and areas of debate surrounding this diagnostic test, and offer practical tips to optimize its performance.
