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

Background: Reconstruction of complex ureteral strictures remains challenging. The appendix provides an autologous alternative for ureteral reconstruction, distinguished from oral mucosal grafts by its intrinsic vascularity. Objective: To describe robotic appendiceal ureteroplasty (RAU) techniques and evaluate their midterm outcomes. Design setting and participants: From May 2019 to September 2024, 31 patients with right-sided complex ureteral strictures underwent RAU at a single institution. All procedures were performed using a robotic single-docking approach. Perioperative and follow-up data were prospectively collected. Intervention: Robotic appendiceal ureteroplasty (RAU) using four different surgical techniques (single-docking approach), depending on stricture location and length. Outcome measurements and statistical analysis: Outcomes included operative time, estimated blood loss, length of hospital stay, perioperative complications, and overall success rate (symptom relief and radiographic patency). Descriptive statistics were used; success rate is reported with 95% confidence interval. Results and limitations: Ureteral strictures were located between the ureteropelvic junction and mid-ureter in 29 patients (93.5%). Mean (range) stricture length was 5.5 (3-25) cm. Mean operative time was 176.4 (99-265) min, estimated blood loss was 42.7 (10-200) ml, and postoperative hospitalization was 4.5 (3-12) days. No open conversions or major perioperative complications occurred. Median (range) follow-up was 28 (12-67) months. The overall success rate was 100% (30/30; 95% CI 88.4%-100%). Limitations include the single-center design, lack of a control group, and limited sample size. Conclusions: RAU is a safe and effective approach for managing complex right-sided ureteral strictures; however, careful patient selection is essential, taking into account both the characteristics of the stricture and the condition of the appendix.
