Abstract
서론
압류량검사는 배뇨시 요속과 방광압을 동시에 측정하여 배뇨근 자체의 이상과 하부요로폐
색 여부를 구분할 수 있는 중요한 검사의 하나이다. 최근 압류량검사는 하부요로폐색을 정
확하게 진단하는 방법으로 보편화되고 있으나 침습적인 방법이어서 모든 환자에게 시행하기
힘들며, 유치시키는 요도카테터의 크기 등의 검사방법상의 여러 가지 요인들이 검사결과에
많은 영향을 주는 것으로 알려져 있다. 실제 임상에서 압류량 검사를 시행해 보면 환자들이
검사시 배뇨 자체를 하지 못하는 경우나, 검사 결과 해석에 있어 논란이 있는 경우 등을 가
끔 본다. 최근까지 전립선비대증 등 하부요로폐쇄가 있는 환자에서 압류량검사의 결과는 많
이 보고되어 있으나 대조군으로서 배뇨장애가 없는 정상성인 남자에서는 보고된 바가 드물
다. 이에 저자들은 배뇨장애가 없는 정상 성인 남자 23례를 대상으로 압류량검사를 시행하
고, 그 결과를 분석하여 하부요로폐색의 진단과 치료에 도움을 주고자 하였다.
Purpose: The pressure-flow study is only objective study that can determine the
presence or absence of bladder outlet obstruction and impaired detrusor contractility.
Although many results of pressure-flow study are reported in diseased state such as
benign prostatic hyperplasia, but are rarely evaluated in adult male patients without
voiding symptoms as control group. The purpose of this study was to evaluate the
findings of pressure-flow study in asymptomatic male patients.
Materials and Methods: Twenty-three male patients without voiding symptom were
recruited for this study. Mean age of these patients was 49.8 years (range 21-70). Mean
AUA symptom score was 1.1(range 0-4) and mean prostatic volume was 27.3gm(range
20-35) on digital rectal examination. The study was done by using 7 Fr. urethral
catheter on sitting or standing position.
Results: Mean values were followed; PdetQmax was 48.1㎝
H2O(range 25-94), Qmax was 15.7㎖/sec(range 3-23), and postvoid residual
urine was 14.5㎖ (range 0-80). According to the Abrams-Griffiths nomogram, 8 were
unobstructed and 4 were obstructed, the remaining 11 falling In the equivocal zone. In
each types, mean group specific urethral resistance factor(URA) was 12.8㎝
H2O in unobstructive type, 51.5 in obstructive type, and 22.1 in equivocal
type.
Conclusions: The results were maybe guessed as following; First, the values of
defining obstrucion were set too low. Second, obstruction was less relevance in the
development of symptoms than had been suggested previously by some observers.
Therefore, we thought that interpretations of pressure-flow finding were carefully
considered to method of test, and/or uncomfortable voiding.
