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

purposeTo compare perioperative and follow-up outcomes of ileal ureter replacement (IUR) among open (O-IUR), laparoscopic (L-IUR) and robotic (R-IUR) approaches.

methodsWe conducted a bidirectional cohort study of patients undergoing IUR for long ureteral strictures between September 2010 and April 2023 in our multi-institutional database. Clinical and follow-up outcomes were compared among the O-IUR, L-IUR and R-IUR groups. Clinical success was defined as symptom-free, stable renal function and no radiographic evidence of obstruction.

resultsAmong 106 patients (23 in O-IUR, 49 in L-IUR and 34 in R-IUR), the three groups had comparable demographic and baseline characteristics. The median operation time was significantly shorter in R-IUR compared to O-IUR (p = 0.029) and L-IUR (p < 0.001). The median estimated blood loss was statistically lower in R-IUR compared to O-IUR (p = 0.002) and L-IUR (p < 0.001). The median length of stay was statistically shorter in R-IUR compared to O-IUR (p < 0.001) and L-IUR (p < 0.001). The rate of postoperative Clavien-Dindo grade III complications was higher in O-IUR compared to L-IUR (p = 0.257) and R-IUR (p = 0.022).

conclusionRobotic ileal ureter replacement demonstrates clear perioperative advantages, consistent with the well-established superiority of robotic platforms in complex reconstructive procedures. However, differences in follow-up duration and potential time/experience bias should be acknowledged when interpreting complication rates.
