Urinary retention arising after syringomyelia surgery is related to anesthesia, which may be taken in combination with lumbar and rigid anesthesia, leading to the possibility of urinary retention after surgery. Patients should be properly relaxed while urinating in bed during urinary retention, and they can do small abdominal massage, and they can be stimulated to urinate by listening to the sound of water next to them, which can be relieved by the above treatments. If it is not relieved, it needs to be treated by medical staff, such as indwelling urinary catheter to draw out the urine, and then slowly adapt to urinating in bed. In fact, the most important factors of urinary retention after syringomyelia are psychological factors and metabolic factors of drugs, etc., among which psychological factors are dominant and still account for a relatively large proportion.
