title: Treatment of ureterosciatic hernia with a ureteral stent.
abstract: A 92-year-old woman was referred to our hospital from a family practice with the chief of complaint of vomiting. Subsequent computed tomography imaging revealed left hydroureteronephrosis without clear evidence of ureteral stones or ureteral tumors and that the lower part of the ureter was shifted to the outside of the cavum pelvis minor from the greater sciatic foramen. Retrograde pyelography was performed, and the shadow of a mass, which constricted and obstructed the distal left ureter, was observed. The patient was diagnosed with ureterosciatic hernia, and a left retrograde ureteral stent was indwelled and the hernia was repaired. Cases of ureterosciatic hernia are very rare. We describe one case of ureterosciatic hernia and review the relevant literature.
