From no bedwetting to continuous bedwetting, it is considered that there is a urinary system related disease, and it is recommended to go to the hospital for examination to clarify the specific cause. There are several possibilities: 1. Chronic urinary retention, where the patient retains a large amount of urine in the bladder and can urinate naturally during the day in normal waking conditions. But at night, because of factors such as incomplete bladder emptying or too deep sleep, and resulting in filling incontinence, bedwetting can occur. It is recommended to go to the hospital for an examination of the external genitalia of the urinary tract and an ultrasound examination of the residual urine to further rule out the presence of urinary retention.2. Urinary tract infections can cause nocturnal urge incontinence and bedwetting due to frequent nighttime rising. Patients have a definite urge to urinate and have an urge to urinate, and they cannot control the incontinence. It is recommended that routine urine tests and urine culture tests be performed to further confirm the diagnosis. 3. If a man has prostate hyperplasia or a history of urethral surgery, he can have sphincter incomplete closure and bedwetting. It is advisable to go to the hospital for prostate related examination and if necessary, urethroscopy for further clarification.
