Laparoscopic ureteral anastomosis to a bladder diverticulum for the treatment of postoperative ureteral fistula: a case report.

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
Objective: To investigate the feasibility and potential indications of laparoscopic ureteral anastomosis to a bladder diverticulum for the treatment of ureteral fistula in the setting of complex reoperative pelvic surgery. Case presentation: A 75-year-old man with a 7-year history of progressive dysuria underwent transabdominal laparoscopic bladder diverticulectomy and cystolithotomy combined with transurethral holmium laser enucleation of the prostate for benign prostatic hyperplasia-related bladder outlet obstruction, bladder stones, and bladder diverticula. Twelve days after surgery, the patient developed increased pelvic drainage output. Elevated drainage-fluid creatinine levels and computed tomography urography showing contrast extravasation from the left ureter with hydronephrosis confirmed a left ureteral fistula. During reoperation, severe adhesions around the left ureter and bladder precluded conventional reconstruction. A bladder diverticulum adjacent to the distal ureter was therefore used as an alternative implantation site, and laparoscopic ureteral reimplantation into the diverticulum was performed. At 4 months of follow-up, no progression of hydronephrosis, recurrent urinary leakage, or urinary tract infection was observed. Conclusion: In selected patients with postoperative ureteral fistula, severe perivesical adhesions, and limited feasibility of conventional reconstruction during complex reoperative surgery, ureteral anastomosis to a bladder diverticulum may serve as an individualized salvage option for urinary tract reconstruction.
