Which type of spinal nerve injury results in loss of bladder control?

The type of spinal nerve injury that results in loss of bladder control is associated with the sacral nerve injuries. The sacral nerves are responsible for innervating the pelvic organs, including the bladder. Injury to these nerve roots can disrupt the nerve signals that control bladder function, leading to incontinence or difficulty in control over urination.

The sacral region specifically manages bladder and bowel functions, along with sexual function, making it a critical area for these involuntary reflexes. When the nerves in this region are damaged, the signals that trigger the bladder to contract or signal when it is full can be impaired, resulting in complications like loss of bladder control. This underscores the importance of the sacral nerves in the autonomic regulation of bladder function.
