[ENDOSCOPIC REMOVAL OF INTRAVESICAL RARE FOREIGN BODY USING FLEXIBLE CYSTOSCOPY: A CASE REPORT]

A 50-year-old man was admitted to our hospital for urinary retention. Computed tomography revealed a spherical intravesical foreign body, measuring 1.7cm in diameter, and cystoscopy revealed glass ball in the bladder. Considering the shape of the object and the possibility of self-insertion, we used a flexible cystoscope, foreign body forceps, and a transvaginal echo probe cover to remove the intravesical foreign body. The end of the echo probe cover was grasped with the foreign body forceps, and a glass ball was inserted into the probe cover and extracted manually with a scooping action similar to using a landing net. No intraoperative hemorrhage was observed, and the glass ball was safely removed with good visual field.The patient's postoperative courses was uneventful, and he has shown no recurrence one year postoperatively.
