The prostate gland is a unique reproductive organ for men, and prostatic hyperplasia is a common disease for elderly men, in fact, there is no prostate organ for women, but older women can also suffer from “prostate disease”. The actual prostate enlargement in women accounts for more than 10% of elderly women, of which about 25% have bladder neck obstruction, early on it can be manifested as frequent urination, urgent urination, increased urination at night, or slow urine flow, dripping incomplete, serious obstruction can lead to chronic urinary retention and difficulty in urination. If the bladder neck obstruction occurs frequently, it can lead to senile vaginitis, chronic urethritis, urethral caruncle and so on. If urine flows backwards through the ureter to the kidneys, it can lead to renal insufficiency and uremia over time. Patients with these symptoms should go to the urology department for early treatment. The early stage can be treated with drugs, but the late stage can only be treated surgically. Currently, surgical treatment with vapor electrosurgery is a good option for treating bladder neck obstruction in elderly women. This procedure makes up for the many defects of open surgical treatment.
