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.
通过尿道插入的异物通常会出现在膀胱中。我们目前报告了首例因硅酮直接压迫膀胱导致的肾盂积水和输尿管积水的病例，该患者在出现严重右侧腰痛前 2 年曾自行将其插入。计算机断层扫描显示膀胱内有一个迂曲、高衰减的肿块；由于肿块的直接压迫，出现单侧肾盂积水和输尿管积水。通过膀胱镜取出了异物。该异物被证实为硅酮。
