In Vitro Effects of a Novel Coating Agent on Bacterial Biofilm Development on Ureteral Stents.

Objectives: Ureteral stenting is a widely used method for noninvasive urinary drainage in ureteral obstruction. However, biofilm development due to transient bacteriuria can cause severe complications such as incrustation with subsequent obstruction as well as recurrent urinary tract infection. Apart from local ailment such as dysuria, this increases both stent replacement frequency and incidence of complications.
