Upper tract heparin instillation for maintenance of ureteral stent patency.
Article in International urology and nephrology, 2023. 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
purposeThe study aimed to evaluate the efficacy of heparin packing after antegrade ureteral stent placement in the renal pelvis to protect against early dysfunction.
methodFrom December 2019 to September 2021, 44 double J (DJ) stent placements were performed with heparin packing (heparin packing group). Between February 2008 and March 2014, 250 DJ stent placements without heparin packing were performed (control group). One-week patency and 3-month patency of the two groups were compared. The patency of the DJ stent according to the blood retention grade in the urinary system was also compared by subgroup analysis.
resultThe 1-week patency rate in the heparin packing group was significantly higher compared to the control group (88.6% and 65.2%, respectively, p = 0.002). There was no significant difference in the 3-month patency rate between the two groups (72.7% and 60.9%, respectively; p = 0.187). In the subgroup analysis, among the patients with high blood retention grades, the 1-week patency rates of the heparin packing group were significantly higher than that of the control group (100% and 60.9%, respectively; p < 0.001).
conclusionHeparin packing through the catheter after DJ stent installation aids in DJ stent patency.
