Every year, there are countless car accidents, mining accidents, and earthquakes, etc. After experiencing these accidents, if they don’t die, there are still a significant number of people who suffer serious injuries, and many of them unfortunately become paraplegic, or even can no longer stand up, and can only be accompanied by a wheelchair or crutches. Paraplegia is more than just an inability to stand up. Patients soon find that the bigger problem they face is urination, which can then become a life-threatening issue. In an international academic conference on urology, a foreign expert asked a Chinese expert about the incidence and treatment of prostate enlargement (a common geriatric disease that mainly causes urinary difficulties) in Chinese paraplegic men, and the Chinese expert said frankly that there was no data on this in China. Upon returning to China, this expert investigated and found that very few Chinese paraplegics lived to the age of prostate enlargement and all died before then. The cause of death is mainly due to paraplegia caused by urinary obstruction, and finally serious urinary tract infection, hydronephrosis, and renal failure. After paraplegia, accompanied by spinal cord nerve injury, there is inevitably a dysfunction of the vesicourethra, referred to as neurogenic bladder. Depending on the site of injury, urodynamics can be manifested as high-tension bladder and low-tension bladder. High-tension bladder is prone to vesicoureteral reflux and hydronephrosis, while low-tension bladder is prone to urinary retention and urinary tract infections, both of which ultimately lead to renal function impairment. At present, in the treatment of voiding dysfunction, patients, as well as some doctors, tend to take voiding as the focus of treatment, and come up with a variety of ways to make patients void, such as abdominal pressure voiding, squeeze voiding, trigger point voiding, etc. Suddenly, one day, it is too late to find renal failure. In hindsight, the goal of neurogenic bladder treatment should be to protect the patient’s renal function while focusing on improving the patient’s quality of life. The principles of treatment are low-pressure storage, low-pressure voiding, adequate bladder ease, and voluntary urinary control. Low pressure ensures that renal function is not impaired, while sufficient bladder ease and autonomous urinary control ensure that patients have a certain quality of life.
