Harnblasenscheidenfistel und -perforation nach Implantation eines Wallstents bei Ureterstenose

The implantation of metal stents in the ureter is an alternative therapeutic option for treating ureteral strictures of different origins. We report the case of a female patient who was treated with a ureteral wall stent because of stenosis caused by radiotherapy. Subsequently the stent migrated into the bladder and led to incrustation and stone formation. This finally led to development of a vesicovaginal fistula and bladder perforation into the os pubis.
