This can cause the inability to void urine even if the bladder is full and cause a large bladder capacity. The internal urinary sphincter can contract normally, however urinary incontinence is common. This type of neurogenic bladder is caused by damage to the peripheral nerves that travel from the spinal cord to the bladder. [5]
Bladder sphincter dyssynergia (also known as detrusor sphincter dyssynergia (DSD) (the ICS standard terminology agreed 1998) [1] and neurogenic detrusor overactivity (NDO)) is a consequence of a neurological pathology such as spinal injury [2] or multiple sclerosis [3] which disrupts central nervous system regulation of the micturition (urination) reflex resulting in dyscoordination of the ...
The parasympathetic nerve supply comes from the parasympathetic preganglionic neurons in the sacral spinal cord and also terminates in the longitudinal and circular smooth muscle layers. Finally the somatic nerve supply arises from the urethral sphincter motor neurons in the ventral horn of the sacral spinal cord; better known as Onuf's nucleus.
The nerves composing it are numerous, and contain a large proportion of spinal nerve fibers. They accompany the vesicle arteries , and are distributed to the sides and fundus of the bladder . Numerous filaments also pass to the seminal vesicles and vas deferens ; those accompanying the vas deferens join, on the spermatic cord , with branches ...
While spinal cord injury is a broad and widely-encompassing term, root stimulators may be used for many instances of SCIs. [3] For example, certain cases of spinal cord injuries may sever key nerves necessary to maintain bladder and bowel control. The severance is often the cause of Neurogenic Bowel Dysfunction. [9]
Dural ectasia is defined as a ballooning or outpouching of the dura with a dural volume greater than two standard deviations above the mean value in controls. [9] It is usually identified by MRI or CT Scan, [7] which can be used to distinguish it from tumors. [16] Radiographs may also be used to identify secondary bone changes. [17]
Whether it’s from an injury or a medical condition, back pain can affect people of any age. And it’s a very common health concern: Approximately 16 million adults suffer from chronic back pain.
Cauda equina syndrome (CES) is a condition that occurs when the bundle of nerves below the end of the spinal cord known as the cauda equina is damaged. [2] Signs and symptoms include low back pain, pain that radiates down the leg, numbness around the anus, and loss of bowel or bladder control. [1]
