An enlarged prostate is prostatic hyperplasia, a common disorder of the male genitourinary system. Electrolysis of the prostate is a well-established surgical procedure and generally has fewer post-operative complications, which may include bleeding, infection, electrolysis syndrome and other hazards. Mild prostatic hyperplasia is less harmful, patients will only show frequent urination, especially increased nocturia, etc., while moderate to severe cases need relevant treatment according to the situation. Prostate electrocision is a minimally invasive treatment technique, which is a surgical procedure to remove part of the enlarged prostate tissue through the urethra. The following complications may occur after the operation: 1. Bleeding: It is mostly caused by incomplete hemostasis during the operation or scabs falling off the wound after the operation, and its main symptoms are hematuria in the naked eye, hematuria under the mirror and so on. 2. Infection: mostly caused by improper cleaning of the perineum after surgery, etc. Its main symptoms are pain in urination, urinary urgency, urinary frequency, fever, lumbago, etc. 3. Electrodessication syndrome: the main symptoms are water intoxication, hyponatremia and so on. 4. Others: such as stress incontinence, urethral stenosis, retrograde ejaculation, etc. It is recommended that patients should have a light diet for one month after the operation, and they need to consult the doctor in time when complications occur, and be treated under the doctor’s guidance.
