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
objectiveTo evaluate the feasibility and outcomes of membrane-guided total intracorporeal laparoscopic reconstruction for ureteral avulsion (UA) following ureteroscopic lithotripsy. MATERIALS AND
methodsFrom January 2021July 2025, eight patients with UA secondary to ureteroscopic lithotripsy underwent membrane-guided total intracorporeal laparoscopic reconstruction. Five patients were treated with the Boari flap technique (BFT), and three underwent ileal ureter replacement combined with Boari flap-psoas hitch (IURBFPH). Preoperative evaluations to assess the ureteral defects included anterograde urography and computed tomography urography (CTU). For all procedures, the membranes were considered during gastrointestinal mobilization and ureteral defect preparation. The postoperative follow-up examinations included urological ultrasound, CTU, and clinical symptom assessment.
resultsAll eight reconstructions were successfully completed intracorporeally without conversion to open surgery. The median length of the UA was 6.50 cm (range: 3.00-18.00 cm). The mean operative time was 362.00 min (range: 240.00-515.00 min), with an estimated blood loss volume of 75.00 ml (range: 20.00-400.00 ml). The mean postoperative length of hospital stay was 12.88 days (range: 7.00-18.00 days). No serious complications or progressive hydronephrosis were observed during a mean follow-up of 9.39 months (range: 1.00-35.00 months), and the success rate was 100%.
conclusionsThe preliminary findings from this case series demonstrate that membrane-guided total intracorporeal laparoscopic reconstruction may be a feasible alternative approach for managing UA secondary to ureteroscopic lithotripsy. However, longer-term functional assessments are warranted.
