Bottom Line: Foreign bodies inserted through the urethra are often found in the urinary bladder.We presently report the first case of hydronephrosis and hydroureter due to direct compression in the urinary bladder by silicon, which had been introduced by the patient himself 2 yr prior to presentation with severe right flank pain.This foreign body was proven to be silicon.

ABSTRACT
Foreign bodies inserted through the urethra are often found in the urinary bladder. We presently report the first case of hydronephrosis and hydroureter due to direct compression in the urinary bladder by silicon, which had been introduced by the patient himself 2 yr prior to presentation with severe right flank pain. Computed tomography indicated a convoluted, high-attenuation mass in the urinary bladder; unilateral hydronephrosis and hydroureter were also present due to direct compression by the mass. The foreign body was removed using a cystoscope. This foreign body was proven to be silicon.

Mentions: A simple pelvic radiography indicated a large radio-opaque lesion approximately 7 cm in diameter in the lower pelvic cavity (Fig. 1A). In order to investigate the possibility of bladder and/or ureteral stone, computed tomography (CT) was performed without a contrast agent. Abdominal and pelvic CT showed a high-attenuation lesion inside the urinary bladder. The lesion was tubular and the thickness was relatively uniform. The lesion blocked the right ureterovesical junction, which was accompanied by right hydronephrosis and hydroureter (Fig. 1B, C).
