Surgery is a more common treatment for bladder cancer, but one of the major disadvantages of surgery is that it may lead to a series of complications that can cause different degrees of harm to patients. The following are the common complications of bladder cancer.
1.Urological symptoms After bladder cancer surgery, patients may experience frequent urination, urgent urination, painful urination or even blood in urination, some of which are caused by surgery, such as damage to the tiny blood vessels around the bladder, which may lead to hematuria.
2, bladder perforation Bladder perforation is a common complication of surgery for patients, as the bladder may be damaged by careless surgery leading to perforation and urinary extravasation. Patients with abdominal pain and distension, which may be accompanied by fever, can normally be treated with a catheter for lasting bladder drainage; if a blood clot accumulates along with the perforation, the patient must be pushed to the operating room for anesthesia to eliminate the clot.
3.Intestinal adverse reactions Intestinal adverse reactions mainly include post-rash feeling, rectal stricture or rectal perforation, intestinal adhesions, intestinal obstruction, etc., which are mainly caused by bladder cancer radiotherapy.
In order to completely destroy the remaining cancer cells, radiotherapy is usually used as postoperative adjuvant therapy. Before pelvic radiotherapy, normal intestinal mucosal cells are sensitive to radiation and may show capillary dilation, edema, congestion, and inflammatory cell infiltration; the continuous and long-term high-dose irradiation of emission rays makes the intestinal mucosal small-vessel lining swell and fibrosis, causing blood transport disorders in the intestinal wall, mucosal erosion, ulceration, intestinal perforation, and abdominal abscess. Intestinal fibrosis and ulcer scar formation can cause intestinal stenosis and intestinal obstruction.
