1. 요속측정 (Uroflowmetry) - average flow rate: 15ml/sec - maximum flow rate: 25ml/sec 2. 방광내압측정 (Cystometry, CMG) - the method by which changes in bladder pr. are measured with progressive increase in bladder volume - evaluate the filling/storage phase of detrusor function - detrusor pr. = intravesical pr. - intraabdominal pr. 1) water vs. gas cystometry 2) normal value - bladder capacity: 400-500ml - bladder pressure: 15cmH2O (mean 6cmH2O) normal voiding pressure: 30-40cmH2O 3) Abnormal cystometry and terminology (1) bladder compliance: V/P (2) involuntary detrusor contraction: a phasic rise in bladder pr. (3) increased detrusor contractility: ① involuntary (uninhibited) contraction: above sacral cord ② low (decreased) compliance: at or below sacral cord detrusor hyperreflexia: in neurologic disease detrusor instability: in the absence of neurogenic disease (4) bethanechol chloride supersensitivity test - no response: myogenic failure - exaggerated: LMN 3. 근전도…
