title: Urodynamic study of bladder function for patients with lumbar spinal stenosis treated by surgical decompression.
abstract: Lumbar spinal stenosis usually leads to different degrees of nerve damage, presenting with back and leg pain, and/or neurogenic bladder symptoms. To determine whether lumbar decompression improved urological function, bladder dysfunction was evaluated in this retrospective study of 26 patients with lumbar spinal stenosis who had undergone lumbar decompression surgery. Urodynamic study procedures were performed pre-operatively and 6 months post-operatively. The Japanese Orthopaedic Association score rating system and Oswestry Disability Index were employed for clinical evaluation. Following surgery, post-voiding residual urine, maximum cystometric capacity and maximum flow rate improved significantly. There was no statistically significant improvement in voided volume, bladder compliance, maximum detrusor pressure or upper urinary tract damage. Urodynamic study was important in the diagnosis of neurogenic bladder dysfunction, prevention of renal deterioration and assessment of post-operative effects after surgical decompression for patients with lumbar spinal stenosis.
