title: Bladder function after surgery for lumbar intervertebral disk protrusion.
abstract: OBJECTIVE
  Urodynamic changes following surgical treatment for lumbar intervertebral disk protrusion were prospectively studied.
  
  
  METHODS
  We evaluated 98 patients with lumbar intervertebral disk protrusion. Urodynamic evaluation was performed in all patients before and after surgery, and included simultaneous measurement of intravesical and abdominal pressure during bladder filling and voiding, and uroflowmetry (pressure flow measurement).
  
  
  RESULTS
  Of the 27 patients with detrusor areflexia preoperatively detrusor activity was normal in only 6 after surgical treatment. Of the 71 patients with normal urodynamic findings preoperatively the findings became abnormal after surgery in 7.
  
  
  CONCLUSIONS
  Bladder function frequently remains unchanged after surgery for lumbar intervertebral disk protrusion.
