Cable Wire as a Nidus for Vesicolithiasis: A Case Report.

Bladder foreign bodies (BFBs) are an uncommon clinical occurrence, often resulting from trauma, self-insertion, iatrogenic causes, or organ migration. These objects can act as nidus for stone formation, leading to vesicolithiasis. Here, we present a rare case of a 61-year-old male with hematuria, dysuria, and abdominal pain. Initial evaluation, including imaging and cystoscopy, revealed a bladder stone encapsulating a foreign object identified as a blue cable wire. Despite denying self-insertion, his history suggested potential unreported trauma. Management involved cystoscopic lithotripsy and foreign body extraction. The case underscores how foreign objects act as nidus for stone formation through inflammatory and biochemical pathways, emphasizing the importance of early diagnosis and appropriate surgical management to prevent severe complications.
