Choosing the right ureteral stent for the right anatomy can be the difference between a successful outcome and a return to theatre. This guide provides clear, informed recommendations for selecting the appropriate Allium URS stent model across the most commonly encountered stricture locations and clinical scenarios.
Ureteral strictures vary significantly in their location, length, and underlying aetiology. A stent that is too short may fail to bridge a stricture adequately; one that is poorly matched to anatomy risks migration, obstruction, or inadequate urine drainage. The Allium URS range, with its self-expanding nitinol design and large-calibre lumen, offers clinicians a targeted solution, but correct selection is essential to realise its full benefit.
This guide is designed to support urologists and specialist nurses at the point of procedure planning, with quick-reference logic for first and second stent choices across stricture locations. The selection guide addresses eight clinical scenarios: UPJ (ureteropelvic junction) strictures, middle ureteral strictures, UVJ (ureterovesic junction) obstruction, ileal conduit (Wallace anastomosis and separate connection point), strictures post renal transplant, inoperable tumours, retroperitoneal fibrosis, and ureteral rupture or fistula. For each scenario, the guide provides a first and second choice stent recommendation, the clinical rationale behind the selection, and supporting anatomical or fluoroscopic images.
