There are risks associated with any kind of surgery, and as a relatively large surgery, radical prostate cancer surgery is certainly no exception. The procedure may cause many kinds of complications, and in severe cases may even result in death. However, in general, the incidence of these serious complications is low and is related to the general condition of the patient and the experience of the surgeon. Specifically, in addition to the risks common to surgery in general (cardiovascular accidents, anesthesia accidents, incisional infections, etc.), the main risks are severe intraoperative bleeding, rectal injury, postoperative penile erectile dysfunction, positive postoperative incisional margins, permanent/temporary urinary incontinence, vesicourethral anastomotic stricture, urethral stricture, deep venous thrombosis, lymphatic cysts, urinary fistula, and pulmonary embolism. Laparoscopic radical prostate cancer surgery may also present with metastases along the incisional implantation, conversion to open surgery, gas embolism, and hypercapnia. In addition, there is a risk of inadvertent injury to the foramen ovale nerve during pelvic lymph node dissection, and patients may experience abnormal walking after surgery.
