W-type suture in Anderson-Hynes laparoscopic pyeloplasty: a novel approach to an old technique.

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
introductionAnderson-Hynes (A-H) dismembered pyeloplasty has remained nearly unchanged since its introduction in 1949. The authors present a modification of the uretero-pelvic anastomosis as described by Anderson and Hynes. The new approach, called the W-type suture, is thought to be more watertight and associated with fewer complications than the original.
aimTo assess the effectiveness of the modification of Anderson-Hynes dismembered pyeloplasty named the W-type suture. MATERIAL AND
methodsThe research is a retrospective study of 99 patients who underwent laparoscopic A-H pyeloplasty. In 49 patients unmodified laparoscopic A-H pyeloplasty was carried out. Fifty patients underwent laparoscopic A-H pyeloplasty with the anastomosis made using the aforementioned W-type suture. To assess the effectiveness of the W-type suture, we compared urine leakage duration - a direct indicator of anastomosis tightness - and frequency of postoperative complications.
resultsThe mean duration of urinary leakage was 3 ±1.16 days for the W-type suture anastomosis group and 3.57 ±1.14 days for the unmodified A-H pyeloplasty group (p < 0.05). The frequency of post-operative complications did not statistically significantly differ between the groups except for fever (18.4% vs. 4%; p < 0.05).
conclusionsThe analysis of the collected data showed that the W-type suture might be a promising alternative to a traditional approach of performing the ureteropelvic anastomosis. Further research should be done to minimize biases present in this study, which might have influenced our results.
