1 · What the graph read from it

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.

2 · The registry

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

Pyeloplasty is generally considered the standard treatment for congenital hydronephrosis associated with horseshoe kidney. We report a case successfully managed mainly by retroperitoneoscopic isthmusectomy without pyeloplasty. Case Presentation: A 23-year-old man presented with left flank-to-back pain. CT revealed horseshoe kidney and left hydronephrosis. The left ureteropelvic junction was considered compressed by renal malrotation, causing obstruction. Retroperitoneoscopic isthmusectomy was performed using an articulating endoscopic linear stapler, resulting in hydronephrosis improvement. Conclusion: In selected patients with horseshoe kidney in whom congenital hydronephrosis is primarily caused by renal malrotation associated with isthmic fusion and aberrant vessel involvement appears limited, treatment mainly consisting of retroperitoneoscopic isthmusectomy using an articulating stapling device may be effective.
