The operation time for bladder cancer ranges from 30 minutes to 3 hours, and the exact time is mainly related to the severity of the disease, the degree of difficulty of the operation and the proficiency of the surgeon, so you need to go to a regular hospital for treatment. For superficial bladder cancer, it takes about 30 minutes to perform electrosurgery; for larger bladder cancer with deeper infiltration, it takes about 1 hour; some bladder cancers require total bladder resection and reconstruction, and the operation time will be extended to about 3 hours. Tumors located in the top wall as well as the bottom wall are relatively complicated to operate, and the operation time will be extended. When the surgeon is highly skilled, the operation time will be shortened. Symptoms such as lower abdominal distension, pain, hematuria, etc. after bladder cancer surgery need to be observed and treated in a standardized way under the guidance of clinicians to avoid delaying the condition.
