The effect of enlarged bladder ileus surgery is mainly related to the patient’s condition, personal constitution, quality of surgery, etc. It has individual variability and cannot be generalized. Vesicourethral enlargement surgery is generally used to treat patients with urinary tuberculosis, non-inflammatory dysuria, female interstitial cystitis, and bladder tumors. Through ileocecal enlargement surgery, the bladder necrotic tissue can be removed, and a part of the ileum can replace the function of the bladder to relieve the pressure symptoms of the bladder and alleviate the patient’s symptoms of frequent urination, urinary urgency, and urinary incontinence. The outcome for the patient depends on the severity of the patient’s condition and the quality of the surgery. If the patient’s condition is mild and the surgery is completed well, the outcome of the surgery is generally better. However, if the patient’s condition is more serious, the individual’s physical condition is poorer, the tolerance level of the surgery is lower, and the surgery is completed less satisfactorily, all of these may affect the outcome of the surgery. Therefore, it is not possible to make a generalization about the results of cystoileus enlargement surgery, but to judge it in the light of the patient’s actual condition.
