“…A biomaterial is de®ned as any substance, natural or synthetic, used in the treatment of a patient which, at some stage, interfaces with tissue [33]. The earliest trials of using implantable prosthetic devices made from glass, tantalum, or vitallium for ureteral replacement failed, due to distal migration or obstruction.…”

This review focuses on technological advances and relevant research related to ureteral stents. The importance of physical and chemical biomaterial type, biocompatibility, material coatings such as hydrogels, and infection related to indwelling ureteral stents are discussed. Recent in vitro and in vivo research has focused on materials that will reduce encrustation and bacterial biofilm formation. The adsorption of antimicrobials onto devices holds promise of reducing infection rates, but multidrug resistant bacteria, short leaching times and adverse side effects make it essential that alternative strategies be investigated. Just so, encrustation limits the long-term use of urinary materials, and a better understanding of factors involved in encrustation are needed to reduce the problem.

“…Biofilms can have a positive impact as well, namely lining the healthy intestine and the female genito-urinary tract. Biofilms have significant implications for clinical pharmacology, particularly related to antibiotic resistance, drug adsorption onto and pealing off devices, and minimum inhibitory concentrations of drugs required for effective therapy (Mardis and Kroeger, 1988).…”

“…In 1988 Mardis and Kroeger observed erosion and bullous edema of the bladder mucosa caused by the lower tip of the stent, which explained the development of macrohematuria and pyuria after ureteral stenting without urinary tract infection. 18 Danilovic et al evaluated the urgent ureteral decompression in patients with ureteral obstruction due to intrinsic and extrinsic pathologies and found that Retrograde double-J stenting failed in 9% (2/22) of intrinsic obstruction and in 52% (13/25) of extrinsic obstruction (p<0.001). 2 Mokhmalji et al evaluated the quality of life of patients undergoing diversion procedure and showed that retrograde ureteral stenting was more problematic and negatively affects the quality of life more than percutaneous nephrostomy.…”
