After neobladder in situ surgery, the patient can urinate on his/her own for about 3 months. In situ neobladder surgery is a surgical procedure in which a section of one’s own bowel is intercepted to make a urinary bladder that is similar to the structure and function of a normal bladder. The bladder is placed in the original position of the original bladder and anastomosed with the ureter and the posterior urethra, so that the urine can be excreted through the new bladder in the original urethra. Generally, patients can urinate on their own about 3 months after the operation, the exact time has some individual differences, and is related to the patient’s postoperative recovery status. However, it takes longer to achieve near normal bladder function, and active bladder exercise after surgery can help improve the prognosis. After in situ neobladder surgery, patients should develop the habit of urinating regularly, adopt squatting or sitting position to help urinate, pay attention to local hygiene, and consult the treating doctor in case of discomfort.
