A case of self-inserted foreign body in the urinary bladder: Usefulness of three-dimensional reconstruction computed tomography for surgery planning

Retrieving intravesical foreign bodies warrants open cystotomy; therefore, preoperative evaluation of the material, size, shape, and location is essential for surgical planning. A 79-year-old man presented with dysuria and admitted inserting a jump rope into his urethra. Reconstructed three-dimensional computed tomography showed an entangled jump rope; therefore an endoscopic surgery was deemed unsuitable. Instead, the rope was removed through a small open cystotomy. He had no complications. Intravesical foreign bodies are not rare, and they should be considered as a differential diagnosis in patients with lower urinary tract symptoms. Three-dimensional reconstruction computed tomography contributes to surgical planning.
