Reported herein is a 41-year-old male who presented for ultrasound due to two episodes of lower urinary tract infections within a period of 5 months. The sonographic examination revealed an elongated foreign body in the urethra extending into the urinary bladder. Self-insertion of foreign bodies into the urethra is usually done for erotic stimulation. However, foreign bodies can be inserted by children due to curiosity and by mentally retarded people, patients with psychiatric disorders as well as by intoxicated patients and in confusional states. Due to embarrassment, the patients seek medical help only when they are symptomatic and hence some of the foreign bodies are removed only several months after insertion. Detection might be either by plain abdominal films when the foreign bodies are radiopaque or by the use of contrast media. In the case presented by us, this was done by sonography. Endoscopic removal of these foreign bodies is considered the treatment of choice. Recurrent or chronic unexplained urinary tract infections should raise a high index of suspicion to the possible existence of a foreign body in the urethra and/or urinary bladder.
本文报告了一名41岁男性，因在5个月内发生两次下尿路感染而接受超声检查。超声检查发现尿道内有一细长异物延伸至膀胱。将异物自行插入尿道通常是为了获得性刺激。然而，儿童可能因好奇、智障者、精神疾病患者以及醉酒患者和意识模糊状态下的患者也会插入异物。由于尴尬，患者仅在出现症状时才寻求医疗帮助，因此一些异物在插入后数月才被取出。当异物不透射线时可通过腹部平片检测，也可使用造影剂检测。在我们所呈现的病例中，是通过超声检查发现的。内镜下取出这些异物被认为是首选治疗方法。反复或慢性不明原因的尿路感染应高度怀疑尿道和/或膀胱中可能存在异物。
