AB  - The presence of a foreign body in the urinary tract may
serve as a nidus for stone formation. A 40-year-old male
was found on CT scan to have a 2.4 cm stone in his
Indiana pouch urinary diversion. As the stone was
fragmented during endoscopic lithotripsy, a metallic
round object was visualized, which was subsequently
established to be a metallic ball bearing. Upon
questioning after the procedure, the patient reported that
4 years earlier he had been accidentally shot with a blow
dart gun and the “miraculous hit” went directly into his
Indiana pouch stoma.
