Lumbar to Sacral Ventral Nerve Re-Routing
Lumbar to Sacral Ventral Nerve Re-Routing
To assess the level of improvement in voiding function after lumbar to sacral ventral nerve
 re-routing procedure in Spinal Cord Injury and spina bifida patients
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.
Inclusion Criteria:

 1. Male and female paraplegics 18 years and older with spinal cord lesion above L1 on a
 CIC program for bladder management and a score of "A" on ASIA scale.

 2. Male and female patients age 6 and older with myelomeningocele spina bifida
 (surgically closed at birth) on a CIC program for bladder management.

 3. Neurogenic bladder documented by urodynamic testing.

 4. Stable neurogenic bladder dysfunction of at least 1 year or more.

 5. Compliant bladder wall.

 6. Normal renal function.

 Exclusion Criteria:

 1. History of bladder cancer, augmentation, or radiation.

 2. Bladder capacity less than 100 milliliters (ml).

 3. Anatomic outlet obstruction or urethral strictures.

 4. Vesico-ureteric reflux grade 2 or higher.

 5. Presence of an ileal conduit or supra-pubic catheter drainage.

 6. Contraindications to general anesthesia or surgery.

 7. Inability to complete follow up visits for 3 years.

 8. Inability to comprehend and answer self-administered questionnaires.
