title: Standard water cystometry and electromyography of the external urethral sphincter.
abstract: Water cystometry and external urethral spincter electromyography permit an accurate diagnosis and provide a rational foundation for treatment of both neurogenic and nonneurogenic vesical dysfunction. The techniques are compatible with and have enhanced our understanding of the pathophysiology of micturition. Properly performed and interpreted, water cystometry and urethral sphincter electromyography a) are an integral part of the work-up of any patient with incontinence or urinary tract infection, b) together with urethral pressure profilometry and uroflowmetry, assist in the selection of those patients who will or will not benefit from attempted surgical correction of incontinence, and c) can be employed to monitor preoperative and postoperative sequelae of major spinal or paraspinal surgery.
