We describe a 32-year-old lady who was admitted with a urinary tract infection following vacuum-assisted delivery. She was diagnosed with Enterococcus faecium related emphysematous cystitis, bladder gangrene and rupture necessitating emergency laparotomy and partial cystectomy. She had a repeat laparotomy nine days later due to continuing bladder necrosis on cystoscopy. The patient stayed in hospital for over two months due to complications including hospital acquired Klebsiella pneumonia, adult respiratory distress syndrome and malnutrition. Discharge occurred one week after an ileal conduit and ileostomy were performed.
