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

aimThe aim of this study was to investigate the factors affecting treatment success in children that got either pyeloplasty or J stent placement in ureteropelvic junction obstruction (UPJO). PATIENTS AND

methodsThe study comprised 126 patients who either J stent placement or pyeloplasty performed by the same physician for UPJO from 2012 to 2022. The criteria for surgical intervention adhered to the European Association of Urology (EAU) recommendations. Symptomatic patients with verified obstruction, with a split renal function (SRF) over 40%, low-grade hydronephrosis (Society of Fetal Urology grade 2), and an obstructive segment measuring less than 1 cm, had Double-J stent placement. Furthermore, in infants exhibiting poor health or development retardation, a J stent was inserted as a temporary measure to alleviate obstruction and maintain renal function, notwithstanding the recommendation for pyeloplasty.

resultsThe treatment success rate was 43.9% in the J stent group and 88.4% in the pyeloplasty group, with a statistically significant difference (p < 0.001). The kind of procedure (pyeloplasty vs. stent) was the sole independent prognostic factor predicting treatment success (HR: 4.77, p < 0.001) in the multiple logistic regression analysis. No statistically significant change was observed in preoperative and postoperative SRF (48% vs. 48.5%, p = 0.923) among patients with stent failure, confirming a transient preservation of functional advantage.

conclusionThe placement of a stent may have restricted success rates in specific patients with UPJO. Preserving renal function may be advantageous until definitive surgery, particularly in cases where there are hazards associated with anesthesia and invasive procedures.
