    Hi
    I had a L4-L5 left disc herniation in December. Feb. 27th my left foot and big toe went weak and numb. MRI showed L5 nerve compressed badly. March 14th I started having frequent urination and urgency. A new MRI showed no central canal compression. And the neurosurgeon didn’t think my urinary symptoms were connected to my back. I also have grade 1 spondylothisis at L5-S1. After my foot went numb and weak I had no leg pain. The local neurosurgeon would only do a L4-S1 fusion. I went to Mayo Clinic for a second opinion because I wasn’t having symptoms from the L5-S1 level. They did a minimal invasive discetomy on L4-L5 MAY 8th. For two weeks following surgery all my urinary symptoms went away and I had no pain. Then after bending over wrong way my leg pain and urinary symptoms returned. I’m also having bad pain where my bladder is. A new MRI showed post operative change of asymmetrical disc bulge to left side which contacts L5 nerve and no central canal narrowing.
    My leg pain has gotten better and I can start to raise my toes off floor so weakness is little better
    My question is it probable that my urinary symptoms and bladder pain are from my disc?
    And should I consider the two level fusion they offered because of urinary and bladder symptoms.

    Neurological urinary symptoms originating from the lower spine typically would be from cauda equina syndrome (a massive disc herniation-see https://neckandback.com/conditions/cauda-equina-syndrome/).

    A disc herniation, no matter how large it is, if it only compresses one side of the canal would not cause cauda equina syndrome as the bladder nerves live on both sides of the canal and both have to be severely compressed to cause urinary symptoms.

    The most common cause of urinary symptoms in my practice is pain inhibition associated with prostatic hypertrophy in men and pelvic diaphragm incompetence from carrying children in women. Either one can cause bladder dysfunction.

    There is no reason to consider fusion due to bladder problems in your case.

    Is it possible that when I stand up the central canal narrows and irritates the bladder nerves? I’ve read of other people having frequent urination/urgency/or bladder pain with disc issues. I know it’s probably uncommon.
    Also do I have to worry about my new disc bulge getting worse and will it get better on it’s own?
    Here is my MRI report
    FINDINGS:
    There are chronic bilateral pars defects at L5 and mild grade 1 anterolisthesis of L5 on S1. Vertebral body heights are maintained. Facet joints are normally aligned. No evidence of acute fracture or subluxation. There are postoperative changes of recent left laminectomy and microdiscectomy at L4-L5. Mild postsurgical fluid remains within the left paraspinal soft tissues at the L4-L5 level. The spinal cord terminates at the L1 level. Signal within the distal spinal cord is within normal limits. The visualized paraspinal soft tissues are unremarkable.

    Segmental analysis:
    L1-L2: No disc bulge, spinal canal narrowing, or neuroforaminal narrowing.

    L2-L3: No disc bulge, spinal canal narrowing, or neuroforaminal narrowing.

    L3-L4: No disc bulge, spinal canal narrowing, or neuroforaminal narrowing.

    L4-L5: There is been prior microdiscectomy at L4-L5. The previously seen extruded left paracentral disc material has been resected. There remains circumferential bulging of the L4-L5 intervertebral disc which is asymmetric towards the left. Bulging disc narrows the left lateral recess and contacts the traversing left L5 nerve root. No spinal canal or neuroforaminal narrowing. Mild bilateral facet arthropathy.

    L5-S1: Chronic bilateral pars defects at L5 and mild grade 1 anterolisthesis of L5 on S1. Mild to moderate left neuroforaminal narrowing. No spinal canal narrowing.

    IMPRESSION:
    1. Status post recent left laminectomy and microdiscectomy at L4-L5. Left paracentral extruded disc material seen on the prior exam from 3/14/2018 has been removed. There remains circumferential disc bulge at L4-L5 which is asymmetric towards the left, narrows the left lateral recess, and contacts the traversing left L5 nerve root.

    2. Chronic bilateral pars defects at L5 and mild grade 1 anterolisthesis of L5 on S1. Mild to moderate left neuroforaminal narrowing at L5-S1.

    Also my X-ray shows that when I stand up L5 slips more on S1 so MRI looks better when I’m lying down.

    One more question is that I have some strength in my big toe but none in my second toe?? Is that from the L5 nerve and do you expect it to get better?

    Your bladder problems do not neurologically originate from your spine problems. An isthmic spondylolisthesis at L5-S1 will typically compress the L5 root which facilitates extension of the great toes and smaller toes. If weak, strength could improve but I would be somewhat concerned if you had foot drop.
