Bladder inflation

In the short period of time during which acute urinary retention occurs suddenly, the bladder is full, and the bladder rapidly expands to become a tension-free bladder with a feeling of bloating and bulging, urgency to urinate, and unable to urinate on its own. Past urination was normal and there was no history of dysuria. A large amount of urine accumulated in the bladder and cannot be discharged is called urinary retention. There are many reasons for urinary retention, and they can generally be divided into two categories, obstructive and non-obstructive. Obstructive urinary retention includes prostate enlargement, urethral stricture, bladder or urethral stones, tumors, and other diseases, and urinary retention occurs when the bladder neck or urethra is blocked. Non-obstructive urinary retention means that there are no organic lesions in the bladder and urethra. Urinary retention is caused by dysuria. Such as brain tumors, brain trauma, spinal tumors, spinal cord injuries, peripheral nerve diseases, surgery and anesthesia can cause urinary retention.
