Endourologic techniques for ureteropelvic junction obstruction therapy. Comparative animal study

Heparin coating in biodegradable ureteral stents does not decrease bacterial colonization—assessment in ureteral stricture endourological treatment in animal model

“…This biofilm remains isolated and protected on the stent surface in a current ureteral stent, but in a BUS, at a certain point the stent surface fragments over weeks, and sweeps biofilm bits containing planktonic bacteria along. We found no differences between the bacteria identified in urine in both experimental groups (E. coli, Enterococcus sp, Enterobacter sp), compared to other studies in a swine model, nor between the most commonly identified bacteria associated with indwelling ureteral stents in patients (32)(33)(34)(35).…”
