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

objectiveTo assess the efficacy and safety of robot-assisted ureteral reimplantation (RUR) ± psoas hitch/Boari flap using anti-reflux techniques for distal ureteral stenosis, with a focus on the prevalence and clinical significance of postoperative reflux-related symptoms.

methodsThis prospective study included 76 patients who underwent RUR ± psoas hitch/Boari flap with an anti-reflux technique between November 2018 and November 2023. Anti-reflux methods included submucosal tunneling or nipple valve reconstruction. Patient demographics, symptoms, laboratory findings, imaging results, perioperative data, complications, and follow-up outcomes were analyzed. Surgical success was defined as symptom relief, improved or stable hydronephrosis, and preserved renal function.

resultsAll 76 procedures were completed successfully, with a median operative time of 141 min and a median blood loss of 20 mL. The overall surgical success rate was 94.5%. During a median follow-up of 13.9 months, 50 patients experienced complete symptom resolution, while 22 reported symptom improvement. Eleven patients reported reflux-related symptoms, such as flank pain during urination, while postoperative vesicoureteral reflux (VUR) was detected in 5 patients via cine magnetic resonance urography. No patients required secondary surgical intervention, and symptoms either improved or remained stable over time.

conclusionRobot-assisted ureteral reimplantation ± psoas hitch/Boari flap with an anti-reflux technique is a safe and effective treatment for distal ureteral stenosis. Postoperative reflux-related symptoms do not necessarily indicate VUR and should not be the sole criterion for further intervention.
