We operated on an 87-year-old female suffering from a giant bladder stone. Her chief complaint was fever and lower abdominal pain, which was caused by lodgement in the urethra. The stone was easily removed in one piece without breakage or injury to the urethral orifice and urethra using forceps normally used for grasping bones in orthopedics. The stone measured 75×50×45 mm and was composed of magnesium ammonium phosphate. To our knowledge, this is the largest bladder and/or urethral stone that was transurethrally removed without being broken. Thus, forceps that are normally used for grasping bones in orthopedics can be used to remove giant bladder stones without leaving stone fragments.
