Materials and Methods: All voided volumes, times and frequencies were recorded in 249 women with overactive bladder. The subjects age related changes in bladder capacity, urinary volume and frequency were evaluated. The causes of nocturnal urinary frequency and its increase with age in older women with OAB were evaluated using 3 days of voiding diaries. Nocturia was devided into three types: nocturnal polyuria, decreased nocturnal bladder capacity and mixed type. Results: Total voided volume, daytime urine volume, functional bladder capacity were decreased with the age. Nocturnal urine volume and nocturnal urinary frequency were increased with age. Nocturnal polyuria was the major cause for nocturia, and mixed type was increased with age. Conclusions: Voiding symptoms as well as storage symptoms were increased with age in OAB female. In most cases, nocturia was caused by nocturnal polyuria.

Wagner 등 (4) 은 30 60세연령군에서남성은 5.7%, 여성은 24.5% 를나타냈고 60세이상에서는남성의 14.5%, 여성의 31.5% 가과민 Vol. 13, No. 1,

5 과민성방광여성에서나이에따른배뇨형태의변화 연령군에서 481±148.6, 60대연령군에서 483±151.8, 70 세이상연령군에서는 483±141.5이었으며각연령군간의비교에서연령이증가함에따라야간배뇨량이증가하였다 (p<0.05) (Table 4). 2) 연령증가에따른주간및야간배뇨횟수의변화주간배뇨횟수는 40세미만, 40대, 50대, 60대, 70세이상군에서각각 7.56±2.01, 7.54±1.98, 7.54±2.12, 7.53±1.87, 7.54±2.31이었으며연령이증가에따른주간배뇨횟수는유의한변화를보이지않았다 (p>0.05) (Table 4). 야간배뇨횟수는 40세미만, 40대, 50대, 60 대, 70세이상군에서각각 1.80±0.85, 1.91±0.68, 1.95±0.74, 2.09±0.59, 2.18±0.54으로연령이증가할수록야간뇨의횟수가증가하였고그중 60세이하와 60세이상과의차이가더욱현저했다 (p<0.05) (Table 3). 3) 연령증가에따른기능적방광용적의변화하루중최대방광용적 (ml) 인기능적방광용적의변화에대한조사에서 40세미만, 40대, 50대, 60대, 70세이상군에서각각 286.5±78.2, 284.6±81.5, 281.1±75.9, 273.2±76.5, 269.4±78.6이었다. 각각의연령군을비교하였을때연령이증가할수록방광용적감소를보였다 (<0.05) (Table 3). 4) 연령증가에따른야간뇨의원인변화배뇨일지분석을통하여야간뇨의유무를조사하고 1회이상의야간뇨를보이는 197명의환자를대상으로야간뇨의원인을분류하였다. 야간뇨를동반하지않는군, 야간다뇨를동반한군, 야간방광용적감소를동반한군, 혼합형, 다뇨가각각 52명, 84명, 46명, 38 명, 29명이었다. 나이가증가할수록야간뇨의빈도는증가하였으며야간뇨의원인으로야간다뇨가가장큰비중을차지하였으며연령이증가할수록야간방광용적감소와야간다뇨가혼합된혼합형이차지하는비율이증가하였다 (p<0.05) (Table 4). 3. 연령증가에따른최대요속및배뇨후잔뇨량의변화배뇨량이 150ml 이상인경우측정된최대요속 (ml/sec) 은 40세미만, 40대, 50대, 60대, 70세이상연령군에서각각 21.56±2.33, 21.89±2.65, 19.11±2.02, 16.02±2.51, 14.95±1.98이었으며연령이증가할수록최대요속이감소하였다 (p<0.05). 배뇨후잔뇨량 (ml) 은 40세미만, 40대, 50대, 60대, 70세이상군에서각각 28.61±9.23, 28.96±8.91, 29.56±9.11, 33.19±8.87, 35.23±9.87으로연령이증가할수록배뇨후잔뇨량도증가하였다 (p<0.05) (Table 3). 고찰과민성방광의유병률은보고자마다다른데그이유는과민성방광용어의정의및진단기준의적용이다르기때문일것으로생각된다. 과민성방광증후군에대한국제요실금학회기준은배뇨근수축의개념을강조하여요역동학적배뇨근불안 (detrusor instability) 혹은불안정방광 (unstable bladder) 으로방광의자극증상을유발하는상태로표현했다 (6,7). 그러나요역동학검사의침습적인문제에대한인식과환자의주관적증상을강조하려는의지로인해, ICS는증명된감염이나다른명백한병변이없는조건하에서절박성요실금의유무에관계없이요절박을보이며대게빈뇨와야간뇨를동반하는증상증후군으로정의하였다 (1,6). 새로운 ICS의정의를이용한과민성방광의유병률은높지는않지만, 2006년발표된 EPIC 연구는유럽및미국, 캐나다등을포함한 19,165명을대상으로한대규모역학조사로이에따르면연령이증가할수록과민성방광의유병률은증가하며 40세이상연령군의 11.8%, 남성의 11.2%, 그리고여성의 18.4% 가과민성방광증상을보인다고하여남성에비해여성에서더높은유병률을나타냈다 (8). 국내에서시행한연구로, 대한배뇨장애요실금학회는 2002년 ICS의정의를이용한 18세이상의남녀 2005명을대상으로하부요로증상과과민성방광에대한유병률조사결과, 전체에서 12.2% 남성에서 10.0%, 여성에서 14.3% 를나타내어외국의경우와마찬가지로여성에서더높은유병률을보고하였다 (9). 과민성방광증상중가장흔하게보고되는증상은요절박과빈뇨인데, 유럽개원가를방문한 211,648명의환자를대상으로시행한설문조사에서빈뇨증상은 Vol. 13, No. 1,

6 41.9%, 요절박은 24.3%, 절박성요실금은 20.2% 의환자가호소하였다 (10). 5502명의아시아여성을대상으로한설문조사결과요절박이 65.4% 로가장흔하게호소하는증상이었고빈뇨가 27.8%, 절박성요실금이 11.4% 를나타내어전반적인과민성방광유병률은 53.1% 라고보고하였다 (11). 본연구에서대부분의환자는요절박과함께야간뇨와빈뇨등의하부요로증상을동시에호소하였다. 과민성방광은모든연령층에서발생가능하고연령이증가할수록과민성방광의유병율은증가한다고알려지고있다 (12). 연령과과민성방광과의연관성을밝히고자하는연구들에의하면연령이증가할수록콜린성배뇨근수축은감소하고 adenosine triphospate (ATP) 를매개로한퓨린성배뇨근수축이중요한역할을하는것으로보고되었으며고령이될수록비신경성아세틸콜린의증가가나타난다고알려지고있다 (13). 그러나지금까지노화자체는과민성방광의직접원인으로는포함되지않고있으므로노인에서보이는과민성방광증상은치유되기어려운질병으로인식되어서는안될것이다. 과민성방광으로분류된환자군의배뇨형태에대한자세한보고는없으며특이연령증가에따른분석을시행한연구는매우드물다. 노인의배뇨형태를배뇨일지를통하여조사한연구들은그결과가다양한데 Kirkland 등 (14) 은하루동안총배뇨량은차이가없으나야간배뇨량이많아진다고하였다. 그러나 Kawauchi 등 (15) 은연령이증가함에따라야간에요량은변화가없으며기능적방광용적의저하를보인다고하였는데야간배뇨량이변화가없는것은물섭취의감소가한가지원인이될것이라고하였고기능적방광용적감소는연령에따른방광저장능력의저하와잔뇨량의증가때문이라고설명하였다. 연령에따른배뇨횟수에대한연구로 Blanker 등 (16) 은주간배뇨횟수는연령에따라큰차이가없고야간배뇨횟수는연령이증가함에따라증가한다고하였으며야간뇨의원인으로야간다뇨와연관이있음을주장하였다. 본연구결과 60세이상연령군에서그이하의연령군에비해총배뇨량, 주간배뇨량, 기능적방광용적이감소하였으며야간요량, 야간배뇨횟수는증가하였다. 그러나주간배뇨횟수는연령군과연령증가에따라큰차이를보이지않았 다. 대부분의환자들은빈뇨, 절박뇨등의자극증상뿐만아니라약뇨, 요주저, 불완전배뇨감등의저장증상도관찰되었고이러한증상은 2 3개씩함께갖고있는양상을보였다. 따라서노인의과민성방광은젊은연령과는다른임상양상을나타내며나이에따른치료의방향을달리적용하는것이증상조절에도움을줄것으로생각된다. 야간뇨는하부요로증상중가장치료가어렵고환자에게고통을주는증상으로알려져있다 (17). 노인연령층의약 72% 이상이원인과무관하게한번이상배뇨를위해자다가일어나고약 24% 는 3회이상의야간뇨를호소한다고하였다 (18). Han 등 (19) 은정상성인남성 158명의배뇨일지를분석한연구에서 48% 가두번이상수면중배뇨를위해일어난다고하였으며 40세이하에서 17%, 50대 32%, 60대 69%, 70대이상의연령에서 85% 에해당한다고보고하면서연령증가에따라야간뇨가현저히증가한다고하였다. 폐경전후의여성에서 3회이상야간뇨가있는군은그렇지않은군에비해수면장애와양호하지않는건강상태를보이며기타질환에대한이환율도높다고하였다 (12). 야간뇨의원인으로는하부요로장애, 수면무호흡등의수면장애, 당뇨나요붕증등으로다양하다 (20). 특히노인에서야간뇨가증가하는원인으로항이뇨호르몬의일간변화의둔화를생각해볼수있다. 젊은연령에서는주간에는항이뇨호르몬이상대적으로감소되고야간에분비가증가하여야간뇨가없으나나이가증가함에따라이러한항이뇨호르몬의변화가나타난다. 또한방광근육의약화및신사구체여과율의변화신장의요농축능력의감소및신혈류의변화가영향을줄수있다 (21). 노인에서심혈관질환이있는경우도주간에신혈류를감소시키며야간뇨를유발한다고한다 (22). Weiss와 Blaivas 등 (23) 의연구에서야간빈뇨의형태를네가지, 즉야간다뇨, 야간방광용적저하, 야간다뇨와야간방광용적저하의혼합형, 그리고다뇨로분류하고야간뇨의원인을분석한결과혼합형이 36% 로가장많았으며야간다뇨를포함한군이 43% 로가장많았다고하였다. 본연구결과, 과민성방광환자의대부분에서야간뇨를호소하였고야간뇨의원인으로야간다뇨가가장큰비중을차지하였으며연령이증가함에따라야간방광용적저 42 대한배뇨장애요실금학회지
