hemorrhoids essential oils,Why does urinary dysfunction or urinary retention occur after anorectal disease surgery?

    The nerves that innervate the anus and urethra come from the pudendal nerve. The sphincter muscles of the anus and urethra are widely connected in the perineum. Therefore, it is easy to directly or indirectly after surgery on the anus.

    Grounding causes spasm of bladder neck and urethral sphincter through nerve reflex, resulting in dysuria or urinary retention.

    Common causes of dysuria or urinary retention are:

    1. The nerve function has not recovered after sacral anesthesia or spinal anesthesia.

    2. Severe pain in the anal area.

    3. Injection or surgical irritation, especially after the anterior anorectal diseases such as anterior internal hemorrhoids are treated by ligation or sclerotherapy.

    4. Compression of packing materials in the anus, such as placing more gauze or gauze in the anal canal at the end of the operation, and the compression bandage after the operation is too tight.

    5. Patients with prostate diseases, such as enlarged prostate or prostatitis, have difficulty in urinating.

    6. Mental and environmental factors, such as excessive stress after surgery, unaccustomed to bed rest or urination in the ward, etc.

    In addition, more men have dysuria or urinary retention than women. This may be related to the shorter female urethra and the longer and curved male urethra.
