Replacement of long-segment ureteral defect with tapered demucosalized ileum: medium-term outcomes of 4 patients.

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
purposeRepair of long-segment ureteral defect (LSUD) is challenging. Currently available procedures carry some potential complications. We modified the ileal graft by tapering the wall and stripping the mucosa to combat associated pitfalls and first reported the medium-term outcomes of 4 patients. MATERIAL AND
methodsFrom September 2019 to October 2020, tapered demucosalized ileum (TDI) was used for LSUD reconstruction in 4 patients on the right (2 males and 2 females). Two patients were with panureteral avulsion and 2 with high-risk urothelial carcinoma in the distal ureter. TDI was made by tapering 1/2-2/3 of the antimesenteric ileal wall and stripping the mucosa with a blunt/blunt operating scissor. Follow-up modalities included serum creatinine, electrolytes, ultrasonography, CT urogram, renal scintigraphy, and ureteroscopy.
resultsMean operation time was 443 min (range 360-550) and blood loss was negligible. The mean follow-up period was 29 months (range 23-36). Vesicoureteral reflux and related pyelonephritis occurred in 1 patient, necessitating a repair operation (Clavien-Dindo grade IIIb). No strictures, obstructions, metabolic disorders, or electrolyte imbalances were observed in the remaining patients. In carcinoma patients, ureteroscopy in month 18 post-operation revealed ileal mucosal regrowth in the form of dwarf isolated islands. All renal units maintained adequate drainage and function during the follow-up.
conclusionsIleal wall tapering and mucosa stripping confined to the muscularis mucosae level will not result in shrinkage, fibrosis, or stricture formation of the ileal ureter. The present work provides evidence for further application of TDI in the replacement of LSUD in patients.
