Onset of symptoms may be after just a few minutes, but usually occurs after at least 20 minutes of free hanging. Typical symptoms are pallor, sweating, shortness of breath, blurred vision, dizziness, nausea, hypotension and numbness of the legs. Eventually it leads to fainting, which may result in death due to oxygen deprivation of the brain.
Chronic urinary retention that is due to bladder blockage which can either be as a result of muscle damage or neurological damage. [7] If the retention is due to neurological damage, there is a disconnect between the brain to muscle communication, which can make it impossible to completely empty the bladder. [ 7 ]
People often have the symptoms for a long time before seeking treatment and the condition is sometimes identified by caregivers. [1] Diagnosis is based on a person's signs and symptoms and requires other problems such as urinary tract infections or neurological conditions to be excluded. [2] [1] Uroflowmetry is also a good diagnostic aid. [8]
Retroperitoneal bleeds are most often caused by major trauma, such as from a traffic collisions or a fall. [3] Less common non-traumatic causes including: anticoagulation. [3] [4] [5] a ruptured aortic aneurysm. [5] a ruptured renal aneurysm. [6] acute pancreatitis. [citation needed] malignancy. [7]
Stenosis: Stenosis of the channel occurs when it becomes narrower, making it difficult to pass a catheter. [11] Additional surgery may be required to ensure the safe insertion of a catheter. [11] If the bladder cannot be emptied via the urethra and the catheter cannot enter the channel, it is a medical emergency. [5]
Although catheter use should be minimized in all patients, particularly those at higher risk of CAUTI and mortality (e.g. the elderly or those with impaired immunity), [2] a meta analysis suggests there is insufficient evidence to determine the value of different policies for replacing long term urinary catheters on patient outcomes.

It is most often due to physical trauma, like a bone fracture (up to 75% of cases) or a crush injury. [3] [6] It can also occur after blood flow returns following a period of poor circulation. [4] Diagnosis is clinical, based on symptoms, not a specific test. [5] However, it may be supported by measuring the pressure inside the compartment. [5]
