[A Rare Case of Spontaneous Knotting of a Urethrally Inserted Cord in an Adolescent Patient].

Abstract

Foreign bodies in the lower urinary tract are occasionally encountered in clinical practice ; however, such cases are relatively rare in pediatric patients. We report a unique case in which a cord inserted through the urethra spontaneously knotted within the bladder, making its removal impossible. To our knowledge, this is the second reported case of spontaneous knotting of a cord in the bladder. A 14-year-old boy presented to the emergency department after inserting a USB cable into his urethra through the external meatus, subsequently failing to remove it. Imaging studies revealed a knotted cord within the bladder. The foreign body was surgically removed via open cystotomy by cutting the knotted portion. The postoperative course was uneventful, and the patient was discharged on postoperative day six.
