Therapeutic efficacy of allium stent combined with balloon dilation as a curative modality for benign ureteral strictures: a retrospective clinical outcomes analysis

The Allium stent demonstrated satisfactory curative potential for benign ureteral strictures (63.36% curative success rate), particularly in shorter strictures. Etiology and stricture length were independent predictors of success. Twelve to twenty-four months appears as the optimal indwelling duration, offering a viable minimally invasive alternative to reconstruction surgery.
