Hello, I had gone through your query and understand your concerns.
Urinary incontinence is a common symptom in pathologies related to hip (or pelvic) bones as
urinary bladder, that holds our urine, is a pelvic organ located near the hip bones.
However in your case, the urinary incontinence is most likely to be caused by the
ruptured disc.
Spinal cord provides nerve supply to urinary bladder and regulates micturition. Injuries to spinal cord is often related to loss of bladder control and thus results in urinary incontinence.
You should not ignore the urinary complications related to spinal or pelvic diseases as these may lead to UTIs or other severe complications.
Urinary incontinence is best treated by using indwelling Foley catheter or by clean intermittent catheterization (CIC).
However I would suggest you to consult your spine ortho or a
urologist regarding the bladder incontinence.
Hope my answer has helped you to clarify your queries. I would appreciate if you post futher queries, if you have. I would be happy to help you. I hope you get well soon and wish you a healthy life ahead.
