요 역 학 검 사

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 …(생략)

3. 근전도측정 (Electromyography, EMG)

4. 요도내압측정 (Urethral pressure profile, UPP)
