Following standardized operating procedures in accordance with the process described in the WHO handbook for guideline development [LINK]. WHO has issued a new recommendation on the length of bladder catheterization following surgical repair of a simple obstetric urinary fistula. Currently the length of catheterization is not standard and ranges from 5 to 42 days. The new guidance recommends a 7–10 day period of bladder catheterization to allow complete healing. Longer periods of catheterization can be inconvenient for the woman, her family and care providers as it is associated with more discomfort and inconvenience. It also increases the risk of infection and erosion related to catheterization; requires more intensive nursing care and costs more per patient. The primary audience for this guideline is health-care professionals, particularly fistula surgeons and nurses providing postoperative care to women after surgery for obstetric urinary fistula. The guideline will also be useful to national and local policy-makers, and staff of nongovernmental and other organizations involved in fistula care services.
