Ureteral stents represent a minimally invasive alternative to preserve urinary drainage whenever the ureter is damaged or is under a significant risk to be occluded due to extrinsic or intrinsic etiology, even due to iatrogenic cause. Ureteral obstruction caused by extrinsic compression is often associated with intra-abdominal neoplasms. The first-line therapy to relieve such obstructions is usually internal drainage with ureteral stents. Ureteral stents made of different materials have been designed to achieve the best drainage possible. In this study, we tried to compare different JJ stent materials – which are better and their pros and cons. The ideal stent that would combine perfect long-term efficacy with no stent-related morbidity is still lacking and stent usage is associated with several adverse effects that limit its value as a tool for long-term urinary drainage. Several new ideas on stent design, composition material and stent coating are currently under evaluation, and are trying to eliminate the drawbacks of ureteral stent usage. Almost every clinician is familiar with the drawbacks that are associated with stents, including infection, encrustation, pain and discomfort.
