Abstract
Foreign body in urinary bladder is an unusual finding in urology emergency, which has always caused wide attention. In this case report, we presented a 28-year-old unmarried male who was admitted to the emergency room with magnetic balls in his bladder. An abdominal plain X ray showed metallic dense shadow in the pelvic region. The foreign body was removed under modified cystoscopy and 159 magnetic balls were detected. The patient was discharged without any surgical or postsurgical complications. Cystoscopy is a better option for dealing with a large number of magnetic balls in urinary bladder.
