A commonly observed symptom of tethered spinal cord affecting organ function is changes in what?

• A. Urologic function
• B. Vision
• C. Hearing
• D. Breathing

Answer: (A)

The key idea is that tethered spinal cord most often disrupts the nerves that control the bladder and bowel. The sacral segments (S2–S4) manage urination and bowel function, and when the cord is stretched or tethered, these pathways can become neurogenic. That leads to changes in urologic function such as incontinence, urgency, frequency, or retention, and sometimes urinary tract infections as the bladder doesn’t empty normally. Vision and hearing are governed by higher brain structures and cranial nerves, not the lower spinal cord, and breathing is controlled by the brainstem and the nerves to the diaphragm and chest wall. So changes in urologic function are the most common organ-related symptom seen with a tethered cord.
