For people with frequent urination after appendiceal perforation treatment, it may be caused by intra-abdominal inflammation stimulating the bladder or urinary tract infection. 1. Intra-abdominal inflammation: after perforation of the appendix, its contents and bacteria enter the abdominal cavity, causing diffuse peritonitis. After treatment, if the abdominal cavity is not washed out during the operation and necrotic materials are left in the abdominal cavity, these materials will stimulate the bladder, thus causing frequent urination. 2. Urinary tract infection: for appendiceal perforation after treatment, there is a chance of urinary tract infection. Such as cystitis, urethritis and other urinary tract infections, the symptoms of frequent urination will appear, accompanied by urinary pain, urinary urgency and other symptoms. When the people with the mentioned symptoms appear, it is recommended to consult a doctor in time for early treatment.
