Abstract:
Polyisobutylene (PIB) is a synthetic elastomer that is a component of sealants, adhesives, and chewing gum base. We report a case of bilateral PIB urolithiasis in a patient with an ileal conduit urinary diversion due to neurogenic bladder from spinal cord injury. Infrared spectroscopy confirmed the composition of bilateral stones and adhesive from the patient's urostomy appliance to be PIB. No previous cases of PIB urolithiasis are reported in the literature.
