Colovesical fistula requires careful pre-operative preparation when the patient presents with active urosepsis, a pelvic abscess, anaemia, or malnutrition. This first-line protocol addresses the measures needed to stabilise and optimise the patient before any planned surgical intervention.

Approach (partial overview): Management centres on medical optimisation — including a targeted antimicrobial approach and, where indicated, interventional drainage — alongside correction of anaemia and nutritional deficits, with the timing of surgical intervention determined by the degree of local inflammation. The complete sequencing, thresholds, and criteria are in the full protocol.

Medical optimization includes control of sepsis while addressing malnutrition and anemia, if present.
Patients with urosepsis should receive an appropriate course of antimicrobial therapy and, if a pelvic abscess is present, consideration for percutaneous drainage should be made for any collection larger than 4 centimeters to expedite resolution of acute sepsis.
Control of sepsis, and correction of anemia and malnutrition when present can shift the patient to elective surgical intervention under more optimal conditions, which can improve the chances of a minimally invasive approach with less conversion to open surgery and lower rate of stoma formation.
