Retroperitoneal Gossypiboma / 대한비뇨기과학회지

ABSTRACT

Gossypiboma is the term used to describe a mass within the body composed of a non-absorbable surgical material involving a cotton matrix. Surgical sponges with radiopaque markers are easily recognized on plain radiographs, but foreign bodies retained in the body without such markers present a diagnostic problem. Gossypiboma should be differentiated from a hematoma, abscess, cyst or tumor. Here we report a case of Gossypiboma in a 60-year-old male patient who had undergone a ureterolithotomy for a right ureteral stone 30 years earlier.
