Endourological treatment of ureteral strictures with the use of self-expanding stents: is it possible to completely cure the stricture endoscopically? A report on the experience with implantation of 35 stents with a two-year follow-up period; a retrospective study.

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
backgroundThe current results of endoscopic treatment of ureteral strictures are characterized by very divergent treatment results, which is due to a wide range of criteria for including patients in the analyses and different definitions of effective treatment. In this retrospect study we wanted to introduce a possibility of curing ureteral strictures depending on their type and degree with the use of self-expanding ureteral stents (SUS).
methods33 patients with ureteral strictures received endourological treatment with the use of Allium® SUS (2 patients with SUS placed on both sides). Patients were divided into 2 groups: patients with uncomplicated strictures (Grp 1) and patients with complicated strictures (Grp 2). Uncomplicated stricture was defined as a single stricture below 2 cm. A complicated stricture was defined as a stricture over 2 cm and/or multiple strictures. The follow-up time was 24 months. All patients were scheduled for renoscintigraphy during the treatment. A full therapeutic success was defined as no tight stenosis in renoscintigraphic furosemide test after SUS explantation.
resultsIn Grp 1, full therapeutic success was achieved in 80% of patients, which was statistically significant (p < 0.001). Serious complications (Clavien-Dindo > 3a) occurred significantly more often in Grp 2 (p = 0.046). Renal outflow during stenting was present in 70% of the patients in Grp 2.
conclusionsA full therapeutic success of endoscopic, SUS-assisted treatment can be considered among patients with short, single ureteral stricture. In long and/or multiple strictures, SUS can be used as drainage element, but full recovery of the stricture is unlikely.
