Stinging in urine after prostate cancer surgery may be a phenomenon that occurs because the body has not yet recovered after surgery, or it may be caused by other factors such as postoperative infection. When patients undergo surgical treatment of prostate cancer, it is necessary to remove the prostate part of the urethra and then reconstruct the urethra and bladder, so urine can cause pressure on the anastomosis, in addition to the stimulation of the urethral mucosa by the catheter that is left in the postoperative period, and other factors will cause a series of symptoms such as urinary frequency, urgency, painful urination, and so on. It takes a long time for the urethra to recover after surgery, and during the recovery period, the symptom of pain when urinating still occurs, and the symptom can be gradually improved with the recovery of the body. In addition, the cause of postoperative urinary pain may also be postoperative infection, infection, retention of catheter during the retrograde infection can easily lead to cystitis urethritis and other diseases, manifested as frequent urination, urinary urgency, urinary pain and other symptoms. It is recommended to go to a regular hospital for a comprehensive assessment of the condition and follow the doctor’s instructions to avoid delaying the condition.
