Ureteroscopy-assisted techniques in laparoscopic repair of middle and lower ureteral stenosis: A retrospective comparative study.
Article in SAGE open medicine, 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
Background: Intraoperative localization of ureteral strictures and safe placement of double-J stents are pivotal steps during laparoscopic reconstruction, yet practical guidance on these steps is limited. Objective: To introduce a simple and feasible new method of using ureteroscopy-assisted localization and indwelling double-J tubes in laparoscopic repair of middle and lower ureteral stenosis, and to confirm its safety and effectiveness. Methods: We conducted a single-center, two-period retrospective comparison of patients undergoing laparoscopic reconstruction for middle or lower ureteral stricture. The control cohort (2010-2017) used conventional laparoscopic localization with trocar-assisted guidewire/stent placement, whereas the experimental cohort (2018-2023) used ureteroscopy-assisted localization with transureteral guidewire/stent placement under simultaneous laparoscopic visualization. Primary outcomes were time to localize the stricture and time to place the double-J stent. Results: A total of 49 patients were included in the experimental cohort and 56 in the control cohort. Ureteroscopy assistance shortened stricture localization time (138 ± 24 versus 174 ± 12 min; mean difference [MD] -36; 95% CI -43.5 to -28.5; p=0.02) and double-J stent placement time (5.2 ± 0.6 versus 9.8 ± 2.4 min; MD -4.6; 95% CI -5.26 to -3.94; p=0.01). Estimated blood loss, drain duration, time to first flatus, and stent malposition rates were similar between groups. Conclusions: Ureteroscopy-assisted localization and transureteral stent placement may streamline laparoscopic reconstruction for middle and lower ureteral strictures by reducing operative time without compromising safety. Prospective studies with longer follow-up are warranted. Ureteroscopy-assisted double-J stent.
