Injury involving T1–L2 spinal segments most likely leads to which problem?

• A. Urinary issues
• B. Visual impairment
• C. Hearing loss
• D. Gastroesophageal reflux

Answer: (A)

The key idea is that the thoracolumbar region (T1–L2) supplies the sympathetic outflow to pelvic organs, including the bladder. When this pathway is damaged, the sympathetic control that helps store urine and keep the internal sphincter closed is disrupted. That disruption leads to urinary problems, often described as a neurogenic bladder with issues like retention or incontinence, depending on the exact injury and how the bladder reflexes are affected.

Other options don’t align with these spinal levels: visual and hearing changes involve cranial and sensory pathways higher up, and gastroesophageal reflux is not primarily controlled by the T1–L2 sympathetic outflow.
