Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Spinal cord injury (SCI) and spina bifida is a source of irreversible injury to the spinal cord often resulting in paralysis and loss of sensation below the waist. The inability to urinate normally is a consequence of both conditions (neurogenic voiding dysfunction). In spina bifida and spinal cord injury, the nerve that controls the bladder and sphincter (the muscle that squeezes the bladder neck to prevent leaking) may no longer work properly resulting in patients who cannot urinate or are constantly wet.

Most patients will maintain high pressures in their bladder and these elevated pressures will eventually take its toll by causing recurrent urinary tract infections, backup of urine to the kidneys, and marked dilatation of possible further damage to the kidneys. Many patients eventually suffer from irreversible renal (kidney) damage, where dialysis or kidney transplant is the only way to sustain life.

Spinal bifida (present at birth) and SCI (occurs most often early in the fourth decade of life) predominately affect young individuals and longevity and quality of life may be greatly reduced by the presence of bladder, bowel, and sexual dysfunction. In the recent past, medications and catheters were the only way to help cord injured patients empty their bladders. Although clean intermittent catheterization (CIC) provides good maintenance results, medications can help conserve low bladder pressures, and antibiotics sustain an infection free urinary tract, these are difficult bladder management programs to uphold. They are expensive, time consuming, and outcomes are inconsistent.

A new surgical procedure has potential for treatment of spinal cord injuries/ spinal bifida. Recently, Dr. Chuan-Guo Xiao from China developed a surgical procedure of rewiring the nerves in the spinal cord to gain better control of urination and avoid complications of neurogenic bladder. The procedure reconnects live wires (nerves) to dead wires.
