title: [A case of neurogenic bladder patient whose pre-void bladder capacity was correlated with the post-void residual volume].
abstract: A 62-year-old male came to our clinic complaining of residual sensation of urine and urinary frequency. He was diagnosed with neurogenic bladder, and has been performing clean intermittent self catheterization once or twice a day. According to his urination record of voided volume (VV) and post-void residual urine volume (PVR) on every urination, we investigated the relationship between pre-void bladder capacity (BC) and PVR. BC was expressed as the sum of VV and PVR. The PVR of BC 300-400, 400-500, 500-600 and ≧600 ml was 141.1, 167.7, 186.8 and 193.3 ml, respectively. PVR significantly increased as BC increased (p＜0.01). Although there are few reports about the relationship between BC and PVR, the present results show that bladder over distension may reduce the contractility of the urinary bladder.
