Minimally invasive surgery for prostate enlargement is usually not painful, but due to the different thresholds of patients for pain, some patients may experience mild pain, but it is mostly tolerable and not a cause for concern. The etiology of prostate enlargement is not yet clear, it may be due to androgen and receptor action, cell proliferation, growth factor neurotransmitters and other factors. Patients with prostate enlargement need to be anesthetized during minimally invasive surgery, and most patients do not experience pain or discomfort during the procedure. However, as some patients have a low threshold for pain, they may be fearful of the surgery and feel pain and discomfort, but this symptom is mostly tolerable and not a cause for concern. After the anesthetic wears off, patients can take an analgesic pump to relieve pain. After surgery, patients with prostate enlargement need to keep the local skin clean and clean to avoid secondary infection. At the same time, patients also need to follow the doctor’s instructions for regular review, in order to understand the recovery of the disease.
