Application of the prior exposure maneuvers urethroplasty in complex posterior anastomotic urethroplasty.

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
objectivesCurrent surgical interventions for pelvic fracture urethral injury (PFUI) are constrained by multiple limitations. This study aimed to introduce the prior exposure maneuvers urethroplasty (PEM-U) in complex posterior anastomotic urethroplasty for PFUI.
methodsFrom February 2018 to March 2023 at Shanghai Ninth People's Hospital, 78 patients with complex PFUI underwent transperineal anastomotic urethroplasty, 39 patients of whom underwent classic Webster urethral urethroplasty in which bodies splitting or an inferior pubectomy after transection of bulbar urethra (Group A), and the other 39 patients underwent improved urethral urethroplasty (Group B), in which using PEM-U (corporeal bodies splitting or an inferior pubectomy before transection of bulbar urethra). Postoperative evaluations were performed at 1, 3, 6, and 12 months after catheter removal. Success was defined as a urine flow rate ≥15 mL/s, no difficulty in urination, and no further intervention was required.
resultsThere was no statistical difference in the length of urethral defect between 39 patients (mean age 43.7 years) in Group A and 39 patients (mean age 41.3 years) in Group B. The average operation time of Group A was 115 min (range, 90-150 min), and that of Group B was 93 min (range, 85-115 min) (p = 0.012). The blood loss was 265 mL (range, 100-650 mL) in Group A and 214 mL (range, 90-350 mL) in Group B (p = 0.015). The success rate was 89.7% in the classical group and 92.3% in the improved group.
conclusionThe PEM-U was effective for treating complex PFUI cases, improving surgical efficacy, reducing the operation time, and the amount of blood loss.
