After cystostomy, it is not recommended to flush often, but you can flush regularly according to the material of the fistula and other aspects, usually once a month. Cyst flushing can easily lead to the lack of mucin on the surface of the bladder mucosa, which can easily increase the risk of infection, and patients are advised to drink and urinate more often to avoid infection and reduce urine precipitation, and usually pay attention to the cleanliness of the fistula and keep it dry. If the cystostomy is blocked, patients are advised to change the urinary catheter immediately. If the cystostomy has bleeding or a large amount of salt secretion, you can consider flushing, but must be under the guidance of a doctor or by a professional doctor and nurse to flush, never flush without permission, self-flushing can easily lead to inflammation in other areas of the body, which can cause cross-infection and other lesions, leading to aggravation of the disease.
