Point Counterpoint Discussion Is TOT enough to ISD Patients? 좌장: 박원희(인하의대) Yes 이동환(가톨릭의대) No 주명수(울산의대) Introduction • In women with SUI, a spectrum of urethral characteristics ranging from a highly mobile urethra with good intrinsic function to an immobile urethra with poor intrinsic function; urethral hypermobility and ISD • There is no standardized terminology or definition for ISD. • McGuire, 1982, referred to ISD as type III incontinence, which he defined as low urethral closure pressure in the proximal urethra regardless of the degree of urethral mobility. • In failed cases with previous suspension technique, presence of ISD suspected --Pubovaginal sling as the choice • Integral theory by Petros and Ulmsten, 1990; TVT, 1996, by Ulmsten • TOT, 2001, by Delorme • Current sales of MUS devices in USA; Transobturator slings make up just over half of the total synthetic sling procedures performed. • Key words; ISD, TVT, TOT ISD가 있는 SUI 환자의 수술적 치료로서; 1. TVT (or SPARC)를 사용한다. 2. TOT도 상관없이 사용한다. 3. Pubovaginal sling을 여전히 사용한 다. ISD의 정의는? • Maximum urethral closure pressure (MUCP) of 20 cm H2O or less by Sand et al., 1987 • Valsalva leak point pressure (VLPP) of less than 60 cm H2O By McGuire et al., 1993 • Other evaluation method ? ISD의 definition • VLPP<60 cmH2O or MUCP<20 cmH2O • Medscape Women Health(1996): Selecting the best surgical option for SUI. Traditional urodynamic evaluation of SUI focusing on MUCP has been found to be less useful than VLPP in detecting ISD. • VLPP<60 cmH2O : ISD • VLPP>90 cmH2O : urethral hypermobility Int Urogynecol J pelvic Floor Dysfunct(2001) Ulmsten • 49명의 ISD 환자에서 TVT 시행 후 4년간 follow up. • 74%-cured, 12%-improved(총 86%에서 성공) • 실패한 7명 중 대부분이 70세 이상의 고령이고 MUCP 가 <10 cmH2O 이하 • Correlation of MUCP, LPP & incontinence severity measure(Int Urogynecol J,2001): MUCP 와 LPP가 낮을 수록 요실금의 정도도 심하 다. 따라서 이들 수치로 요실금의 정도를 예측할 수 있고, ISD를 평가하는 기준이 된다. 그러나 이 들 수치가 pad test 양, QOL과는 상관없다. 기타 ISD를 확인하는 방법 • Int. Urogynecol J Pelvic Floor Dysfunct(2002) : video-UDS로 resting 시 및 복압증가시 bladder neck 의 모양으로 ISD를 다시 A,B,C 의 subtype으로 구분. • 2008년 Smith & Appell등은 ISD환자는 요도의 저항이 낮으므로 UFM시 요속이 정상보다 더 빠를 것이라고 생 각(superflow), UFM로 ISD를 예측할 수 있지 않을까 라고 주장 • 2006년 Olivera등 – translabial ultrasonography로 urethra diameter를 측정, 6 mm이상이면 ISD라고 주장 • 가장 최근 Klarskov(J Urol. 2009), urethral pressure reflectometry(very thin, highly flexible polyurethrane-bag into urethra)로 요도 전체의 압력 을 측정하는 방법을 제시 Is it possible to diagnose ISD in women ? Curr Opin Urol. 2009 • There’s some evidence women with ISD have a poorer outcome if they are treated by TOT compared with TVT. • There have been some attempt at using ultrasound to identify ISD, but without any definite conclusion. • Conclusion: ISD is an imprecise diagnosis. Definition of ISD • Low pressure urethra: • Indicator of ISD • Depends on age, measuring methods, circumstance • 1976년 McGuire • 수술 실패와 연관된 요인으로 저요도압을 보고 • AHCPR (Agency for Health Care Policy and Research) • A cause of genuine stress incontinence: ‘. . . which may be due to congenital sphincter weakness such as myelomeningocele or epispadias or may be acquired after prostatectomy, trauma, radiation, or sacral cord lesion. In this condition, the urethral sphincter is unable to coapt and generates enough resistance to retain urine in the bladder, especially during stress maneuvers. In women, ISD is commonly associated with multiple anti-incontinence procedures. Patients with ISD often leak continuously or with minimal exertion. McGuire EJ, Lytton B, Pepe V, Kohorn EI. Stress urinary incontinence. Obstet Gynecol 1976;47:255–264 Definition of ISD: Assessment Bent AE. Selection of treatment for patients with stress incontinence. Int Urogynecol J 1999;10:213-4 ISD의 임상적 의미는? • ISD 유무에 따라 수술 방법의 선택이 달 라지나요? • 어떤 수술을 시행하더라도 tension조정이 나 다른 특별한 방법을 사용하나요? Clinical significance of ISD • Int Urogynecol J Pelvic Floor Dysfunct(2002): VLPP and/or MUCP is abnormal, incontinence is more severe and the incidence of poor prognostic factors is increased. • Neurourol Urodyn(2003): ,,,we divided the patients into two categories: 50 patients affected by pure ISD as they had severe SUI and no urethral mobility, 42 patients suffering from SUI without ISD as they had mild SUI and marked urethral hypermobility. • 즉, ISD는 AI 에 비해 요실금의 양도 많고, 빈도 도 잦다는 의미로 해석될 수 있다. • Definition of mild, moderate, severe incontinence on 24-hr pad test: BJOG(2004) -24시간 pad test에서 측정된 실금의 양을 기준 으로 mild는 1.3~20g, moderate는 21~74 g, severe는 75 g 이상으로 하자. • 이 결과에 따라 보존적 치료를 할 것이냐, 아니 면 수술을 선택할 것이냐를 결정하고, 수술 후 cured, improved, 또는 failure를 판단하는데 도 움을 줄 것으로 기대. ISD affects the choice of surgical methods ?? • Surgical Treatment of SUI: Eur J Obstet Gynecol Reprod Biol (1999) : International classification as: Type 1 & Type 2(AI), and Type 3(ISD). • Procedure of choice for Type 1 & Type 2 is BNS that create a strong hammock. Type 3 has to be treated by coaptation or compression of the deficient sphincteric unit(sling or injection). Mean cure rate after MMK is 77%, Burch is 81%, needle suspension is 79%. Laparoscopy, bone anchor & TVT represent a promising option to the traditional techniques. Curr Opin Urol(2004) • There remains NO clear consensus as to whether UDS enhances surgical outcome of SUI by improving case selection or altering the surgical approach based on study finding. • It is NOT apparent either VLPP or MUCP can accurately predict which patients will achieve the best outcome of surgical treatment for SUI. Clinical significance of ISD • Grade of ISD • ISD A : medical, with collagen injection being used for the failed cases • ISD B : modified PVS (can correct IDS and hypermobility) • ISD C : urethrolysis and take down of previous suspension was required before using a sling, collagen injections in selected cases Ghomiem GM et al. Int Urogynecol J 2002:13:99-105 Clinical significance of ISD • MUCP and VLPP : different mechanism? • MUCP ≤ 30cmH2O • more severe incontinence • Shorter urethral functional length • Previous urogynecological operations • Menopause • Older age • VLPP ≤ 60cmH2O • more severe incontinence • Shorter urethral functional length • Previous urogynecological operations • Poor urethral mobility Pajoncini C et al. Int Urogynecol J 2002:13:30-5 Surgical options in ISD • • • • Pubovaginal sling TVT : initial and failed cases TOT : 낮은 성공률을 감안하여 환자와 상의, tension Injection therapy : initial and adjuvant (hypermobility) Lee KS et al. J Urol 2007:178:1370-4 ISD환자의 수술적 치료에서 수술방법에 따른 성적의 차이가 있나요? • 수술 방법의 차이에 대한 evidence 수준은? ISD 유무에 따른 수술 후의 성적 • 2004년 Rodriguez(J Urol): 174명의 환자에 sling 수술 • VLPP-not detected(60명), >80(27명), 30-80(71명), <30(16명) 으로 구분 • VLPP치와 무관하게 대부분에서 성공률이 높았다 • 2007년 Porena등(Eur Urol): VLPP>,<60, MUCP>,<30 으로 나누어 TVT, TOT를 시행, 각 군간에 그리고 수술방 법간에 차이가 없다. MUS to ISD Patients • TVT in ISD patients (3-4year FU) • SUI / recurrent / ISD 84.7% - 90% / 82% / 74% • TVT 5year FU (retrospective) Rezapour M et al. Int Urogynecol J 2001;(Suppl 2):S12–14 Doo CK et al. Eur Urol 2006:50:333-8 TOT to ISD Patients • Risk factors for MUS • Preop DO and MUCP ≤ 40cmH2O (TOT Monarc) • Age ≥ 60years, previous anti-incontinence surgery (TVT-O) • MUCP ≤ 30cmH2O, previous anti-incontinence surgery (TVT-O, ARIS) • TOT comparison to TVT • Cure rate worse in TOT; possible explanation is ISD (RTC) • Monarc: 6 times more likely to fail than TVT in pts c MUCP ≤ 40cmH2O Hsiao SM et al.

The role of urethral hypermobility and ISD on the outcome of TOT procedure: prospective study - Int Urogy J Pelvic Fl Dysf, 2010 • group I, ISD with hypermobile urethra (n = 18) group II, ISD with fixed urethra (n = 16) group III, hypermobile urethra without ISD (n = 31) • RESULTS: The cure and improvement rates of groups I and III were similar(87.5% vs 96.4%). Group II had the lowest cure and improvement rates (66.7%). • CONCLUSION: A lack of urethral hypermobility may be a risk factor for TOT failure.
