nerve damage or relaxed pelvic floor?

  I am a 41y.o. female with 2 children (2 & 6).
  I first started noting urinary leakage after
  the birth of my first child when I would jog. and
  sometimes with a lot of sneezing and coughing.
  This stayed about the same after the birth of my
  second child (both were small to medium babies,
  and I have a medium build).  In Jan. I was
  diagnosed with a large neuronoma at L1/T12
  that had been causing back pain and sciatica.
  This was surgically removed in early Feb.
  Since that time my back symptoms have improved
  dramatically.  I have recently started jogging again
  a small bit, but much to my chagrin I have
  noticed I am still having urine leakage.Any ideas
  about the diagnotic picture and treatment?
  Thanks!

Dear NN Thanks for your questions.
It sounds like you have  stress incontinence, but it can be difficult to tell especially since you have a history of a neurologic lesion.   Here is some general information  to see what best applies  to you.  
  Behavior modification is the first line of treatment for Stress and Urge   incontinence. Volitional urination before the urge is felt (timed voiding) and  decreasing the amount of fluid intake, especially caffeine,  are  ways of decreasing the amount and frequency of leakage.   Kegel exercises are also helpful for the well motivated patient.  Antihistamines like phenylpropinolamine, are over the counter meds which can help tighten the sphincter(outlet) of the bladder and may help stress incontinence if leakage is a small amount.  Surgery  is usually for patients who have failed conservative therapy and may require overnight admission.  If you are considering surgery,  urodynamics ( a bladder test which looks at the filling and emptying of the bladder)  may be recommended by your urologist.  This test helps rule out other contributing factors which may compromise your surgical results. Two surgical options are available and one may be more suited based on  your pelvic exam.  Collagen injection of the bladder neck (performed as an outpatient)  may help  patients who leak urine very readily.  A bladder suspension is indicated for women who
