[Bladder calculus after augmentation ileocystoplasty in children].
Of 12 children who had undergone augmentation ileocystoplasty for treatment of neurogenic bladder, 3 developed bladder calculi 9 to 19 months after the operation. All these 3 children had simultaneously undergone procedure to ensure urinary continence together with ileocystoplasty, and postoperative persistent bacteriuria was found in these 3 children. Component of bladder calculi was magnesium-ammonium phosphate in 2 and calcium phosphate in the other child, and all were successfully removed by endoscopic lithotripsy. These data suggest that postoperative persistent bacteriuria as well as procedures to ensure urinary continence might play a role in the formation of bladder calculus after augmentation cystoplasty.
