A sonographic pitfall in penile fracture: Spongiosal displacement mimicking urethral injury, with surgical correlation.
Article in Radiology case reports, 2026. 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
Penile fracture is a urological emergency in which high-resolution ultrasound can help localize tunical disruption and define associated soft-tissue injury. We report a 40-year-old man who sustained penile fracture during intercourse in the female-superior position. High-resolution ultrasound with color Doppler (Voluson E8, 12-15 MHz linear transducer) identified a tunical defect at the mid third of the dorsal surface of the left corpus cavernosum, measuring 7.8 × 2.6 mm, with an intracavernosal hematoma measuring 33.9 × 21.7 × 32.0 mm and causing marked lateral displacement of the corpus spongiosum. Because this displacement raised concern for associated urethral injury, the urethra and corpus spongiosum were assessed in multiple transverse and longitudinal planes. Preserved spongiosal echotexture, visualized continuity of the urethral course, absence of perispongiosal fluid, and preserved Doppler perfusion supported preservation of urethral integrity. Same-day surgical exploration confirmed the tunical tear, intact corpus spongiosum and urethra, and hematoma containment within Buck's fascia. No MRI, retrograde urethrography, or cystoscopy was required in this clinically concordant case. This case illustrates how hematoma-related spongiosal displacement may mimic urethral injury and shows the complementary value of systematic multiplanar ultrasound in pre-operative assessment. Additional urethral imaging or endoscopic evaluation remains appropriate when clinical or sonographic suspicion persists.
