Hi,
There can be many reasons for urine retention in a your daughter.
Mechanical/anatomical causes include
urethral stenosis, foreign objects, bladder stones, constipation, urethral cancer, uterine fibroids, bladder-neck obstruction, pelvic organ prolapse, cervical cancer and anti-incontinence surgery.
Functional or neurological causes of
urinary retention in women include cerebral and spinal cord diseases which can be congenital, neoplastic, degenerative, inflammatory, vascular or traumatic, e.g.
spinal cord injury (suprasacral), multiple sclerosis,
Parkinson’s disease, cauda equina syndrome and Fowler’s syndrome.
It is important to know what is the diagnosis made on CT scan stating that the kidneys are not functioning properly.
The problems with the kidneys might have arisen due to obstruction in the flow of urine from the urinary bladder to the exterior. If there is persistent obstruction to the flow of urine then there are back pressure changes from the urinary bladder in to the kidneys. If such an obstruction continues for more than 10 days then permanent damage to kidney function is possible and this is called
obstructive uropathy.
