Is stem cell therapy useful for neurogenic bladder?

Hi doctor,

My daughter, who is 22 years old, has neurogenic bladder. Her height is 4'10" and weight is 53 kg. She is suffering from voiding dysfunction and constipation. She underwent surgery for spinal lipoma when she was 45 days old. Her bladder trabeculated and grade 3 reflux. Her right kidney is 8.83 x 4.89 cm and left is 9.40 x 4.08 cm. She had been on Nitrofurantoin 100 mg and Tolterodine tartrate 2mg per day (bed time) for six years and discontinued three months back. Kindly advice on appropriate treatment option and prognosis. I would like to know if stem cell therapy is useful. I have attached her reports for your reference.

Thank you doctor,

She voids twice in the night at around 10.30 PM and 5 AM. In the meantime, she does not wake up for urination. Her urologist advised to discontinue prophylactic use of Nitrofurantoin so that she can go for antibiotic when she requires it.
