Materials and Methods: From August 26 to December 28, we reviewed the medical records of 261 patients underwent Canal TOT in Division of Urogynecology, Department of Obstetrics and Gynecology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine in Seoul. This study is a retrospective analysis of the clinical characteristics (age, gravida, parity, body mass index), previous operation history, comorbidity, surgical procedure and operation outcomes. We performed stress test, one hour pad test, urodynamic study, postvoid residual assessment to all patients for diagnosis of SUI. All patients answered self assessment questionnaires (IIQ-7, UDI-6) at 6 months and 12 months after operation. Results: 55 women over 65 years were underwent Canal TOT. Mean follow up was 11±4.5 months. Mean age of patients was 7.2±3.9 years, gravida 5.8±2.3 times, parity 3.9±1.5 times and body mass index (BMI) 25.6±3.1Kg/m 2. 8 patients had got hysterectomy (14.5%). 16 patients (29%) had sling operation (Canal TOT alone), and 39 patients (71%) had Canal TOT combined with vaginal surgery for pelvic organ prolapse. The cure rate was 96.4% in 6 months follow up. Leakage after operation were reported by 2 patients (3.6%) and 3 patients (5.5%) transiently suffered from postoperative voiding difficulty. Of whom had incontinence complexed with overactive bladder symptoms (frequency, nocturia, and urgency) 12 patients complained of persistent symptoms after Canal TOT (12/33, 36.4%). 1) 접수일자 : 29 년 12 월 4 일, 수정일자 : 29 년 12 월 16 일, 채택일자 : 29 년 12 월 23 일교신저자 : 이교원, 성균관대학교의과대학산부인과학교실서울시종로구새문안길 78 ( 서울시종로구평동 18 번지 ) 우 Tel: , Fax: , kw4773.lee@samsung.com Vol. 13, No. 2,

2 최경미 이세진 이정훈 최중섭 김계현 한종설 이교원 The scores from self assessment questionnaires (IIQ-7, UDI-6) at6months after operation were improved significantly. Conclusion: Canal TOT is feasible and safe method for SUI in old age. The procedure also shows favorable results when combined with other operations for pelvic organ prolapse.

SPSS15.을사용해 Pearson Chi-square test를실시하여통계치를구하였다. P<.5인경우를통계적유의성이있는것으로판단하였다. 결과 26년 8월부터 28년 12월까지 Canal TOT 수술을받은 65세이상환자는 55명이었다. 평균나이는 7.2±3.9세, 평균임신력 5.8±2.3회, 평균분만력 3.9±1.5회였다. 체질량지수는 25.6±3.1kg/m 2 였으며기저질환이있는환자는 32명 (58.2%), 이전에자궁적출술을받았던환자는 8명 (14.5%) 이었다. 슬링수술만을 받은환자는 16명 (29%) 이었고골반장기탈출증수술을함께받은환자는 39명 (71%) 이었다. 평균추적관찰기간은 11±4.5개월이었다. 평균수술시간은 86±45 분, 평균혈색소치변화는 1.5±1.2mg/dL였다. 수술후방광천공, 요도손상, 혈종, 수술부위감염과같은수술합병증은발생하지않았다 (Table 1-3). 65세이상의복압성요실금환자에게시행된 Canal TOT의치료율은수술후 6개월에 96.4% (53/55) 이며수술후요실금증상이지속된환자는 2명 (3.6%), 수술후일과성배뇨곤란이발생한환자는 3명 (5.5%) 이었다. 요누출이지속된환자 2명중수술전요역동학검사에서요로의내인성괄약근기능부전 (intrinsic sphincter deficiency: ISD) 을나타낸경우는없었다. 요누출이지속된환자중 1명은슬링수술만받았던환자로수술후 2일째에 mesh plication을시행하였고, 현재증상재발없이 24개월간추적관찰중이다. 요누출과빈뇨, 절박뇨를함께호소하던다른환자는슬링수술과방광류및직장류복원술을같이받았으며수술중방광경검사에서방광암 (bladder cancer in situ) 이발견되어비뇨기과로전과되어치료를받았던환자이다. 일상적인기침유발검사에서는요누출이관찰되지않았으나서있는자세에서는요누출이확인되었다. 보존적요법을함께시행하여 3주후요누출증상은호전되었으나빈뇨와절박뇨는약간호전된상태로지속되고요누출은일주일에 2 3회나타나는상태로 3개월간추적관찰중이다. 배뇨곤란을겪었던환자 3 명은모두방광류복원술과직장류복원술을함께받은환자였다. 2명의환자는 1주간의도뇨관유치후자연배뇨가가능해졌으며나머지환자 1명은자연배뇨는가능하였으나 15mL 정도의잔뇨가지속되어청결간헐도뇨 (clean intermittent catheterization: CIC) 가 4 주간필요하였다 (Table 3). 복압성요실금에과민성방광증상 ( 빈뇨, 야간뇨, 절박뇨 ) 이동반된환자들 (33명) 중과민성방광증상이지속된환자는 12명 (36.4%) 이었다. 새롭게발생한절박뇨를호소하는환자는없었으나절박성요실금이동반되었던환자 1명은슬링수술후에도증상이지속되었다. 수술후 6개월째에설문조사형태로삶의질개선효과와수술법의치료효과를평가하였다. 사용한설문 Vol. 13, No. 2,

TOT 시술시에는 TVT와같이정중요로접근법 (midurethral approach) 을시행할때전질벽의 midurethral level에서정중절개후에 periurethral fascia를박리한후손가락유도 (finger guide) 하에회음부찌름절개창 (perineal stab incision) 과질벽절개사이로바늘을통과시켜슬링을걸어주게된다. 이과정에서질벽절개선이확장되고, 요도조직 (urethral tissue) 을직접손상할가능성이높아지며, 폐쇄공막을정확하게촉지하기가실제적으로어렵고, 바늘이통과하는위치가대퇴주름에서 one finger breath만큼외측으로나가게된다. 이과정에서일어난방광천공, 요도손상등이이 Vol. 13, No. 2,
