[Ureteral stenosis caused by pelvic actinomycosis]

The authors report a case of pelvic actinomycosis causing ureteral obstruction in a 30-year-old woman. An intra-uterine device being in place for 6 years is considered as the main cause. The treatment, which included a laparotomy for abscess drainage, an indwelling double pigtail ureteral stent and a 9 month antibiotherapy led to recovery after an initial relapse.
