Top panel: Axial section of CT of abdomen performed five days after vesical lithotripsy: A 8
× 5.6 cm area of high attenuation within slightly distended urinary bladder was seen, which represented clots within the urinary bladder. The outline of urinary bladder was intact. Urinary catheter was in situ. Bottom panel: Axial section of CT abdomen with oral positive contrast, performed 12 days after vesical lithotripsy (two days after cystoscopy and clot evacuation) when the patient developed abdominal distension: A large 9 × 8 × 4.5 cm intra-peritoneal haematoma, at the superior aspect of dome of urinary bladder. There was 2.5 × 2 cm defect/perforation of the urinary bladder wall superiorly at the site of the haematoma).
