title: [Evaluation of micturitional disturbance in spinal disorders: reproducibility of uroflowmetry].
abstract: Patients with spinal degenerative diseases suffer not only neuropathy in the extremities but also lower urinary tract dysfunction(LUTD). Patients with cauda equina syndrome generally need emergency decompression to pelvic visceral function, especially that of the urinary bladder. However, less prominent voiding symptoms can be missed in clinical settings. There is a discrepancy between lower urinary tract symptoms and LUTD. Therefore, urodynamic studies are needed to screen of patients with spinal diseases. Cystometry and urethral sphincter electromyography are useful for increasing our understanding of LUTD but are too invasive for screening. Our protocol for the evaluation of LUTD consists of residual urine measurement and uroflowmetry(UFM). UFM is the simplest and noninvasive urodynamic technique;however, it has the disadvantage of being nonreproducible, which depends on bladder volume, diurnal variation, presence of obstructive disease, and mental stress. UFM was reportedly reproducible in normal individuals in 1979, but was not evaluated in patients with spinal disease. This study examined the reproducibility of UFM in patients with spinal disease. UFM was performed twice in 26 male patients with cervical or lumbar degenerative disease. Maximum urinary flow rate corrected with Siroky's nomogram was reproducible in 23(88.5%)of the 26 patients. A urinary flow curve was reproducible in 25(96.2%)of the 26 patients, and only 1 patient had excessive urination at the 1st UFM and normal urination at the 2nd UFM. The reproducibility of UFM was high in patients with spinal degenerative disease.
