In daily medical practice, we occasionally encounter patients with a foreign body in the urinary bladder. However, the identification of such a foreign body in an adolescent and the occurrence of an urethrocutaneous fistula caused by the foreign body are extremely rare. Only two cases have been reported previously. Herein we present a case of a foreign body in the urinary bladder and an urethrocutaneous fistula in a young patient. A 14-year-old boy with fever, left scrotal pain and urinary incontinence was referred to our department. Intravenous pyelography and micturition cystourethrography findings revealed a vesical foreign body and an urethrocutaneous fistula. He mentioned that he had inserted two dozen magnets into the urethra for masturbation one year previously. As the foreign bodies were spherical small magnets, we performed transurethral surgery and successfully removed the magnets. His postoperative course was uneventful and he was discharged from our department on the seventh day after surgery. Three months following surgery, the fistula had closed spontaneously.
在日常医疗实践中，我们偶尔会遇到膀胱内有异物的患者。然而，在青少年中识别出这样的异物以及由该异物导致尿道皮肤瘘的情况极为罕见。此前仅报道过两例。在此，我们呈现一例年轻患者膀胱内有异物并伴有尿道皮肤瘘的病例。一名14岁男孩因发热、左侧阴囊疼痛和尿失禁被转诊至我科。静脉肾盂造影和排尿性膀胱尿道造影结果显示膀胱内有异物及尿道皮肤瘘。他提到一年前为了手淫将两打磁铁插入尿道。由于异物是球形小磁铁，我们进行了经尿道手术并成功取出磁铁。他术后恢复顺利，术后第七天从我科出院。术后三个月，瘘管已自行闭合。
