Patients in the outpatient clinic often have frequent urination, difficult urination, and incomplete urination as their main complaints, although there are no epidemiological surveys, and are often seen as teachers, bank employees. There are also chefs in restaurants, active duty military personnel, and bus drivers. These people have a characteristic that they often hold their urine, and when they feel like urinating, they often cannot urinate normally, and often hold it until they have to pee their pants before they have to go. Over time, from the beginning, the volume of urination is larger, and then there is a feeling of incomplete urination. After repeated treatment, the urodynamic examination performed at our hospital often indicates delayed bladder urination sensation, increased compliance, weakened bladder contraction and increased residual urine. When encountering such patients, some doctors often just give drugs that may relax the smooth muscle of the urethra, but do not guide the patient’s habits and urinary patterns, so that they drink the right amount of water and urinate regularly, so the treatment is not effective, and often after changing their habits, the patient’s residual urine will slowly decrease.
At present, in many hospitals, patients are often voided every two hours after surgery because of the indwelling urinary catheter, in order to exercise the bladder, which has a very nice name “bladder exercise”. Personally, I think it is inappropriate, because postoperative patients are often given a lot of fluids, and within 2 hours the patient’s urine volume sometimes exceeds their physiological bladder capacity, which causes perceived urinary retention and leads to damage to the patient’s detrusor muscle, rather than playing a role in recovery. Sometimes this is more likely to happen when the patient is not fully awake from anesthesia after surgery.
