Results of the tension-free vaginal tape procedure for stress incontinence: Patient''s perspective

BACKGROUND: To evaluate the results of the tension-free vaginal tape procedure (TVT) from a patient's perspective. METHODS: Between May 1999 and January 2002, 90 patients underwent a TVT for genuine stress incontinence (GSI) and mixed incontinence. Prior to the procedure, GSI was confirmed by clinical examination and urodynamic studies. Results were then audited from patient notes and the same patients were sent questionnaires to examine results from a patient perspective. RESULTS: Overall response rate to the questionnaire was 70 (77%). The mean age of the patients was 50.4 years (range 31-83 years). Sixty-one patients had spinal anesthesia, seven had general anesthesia and two had local anesthesia. Mean hospital stay was 3.36 days (range 2-14 days) and mean period from the operation to the time of the survey and audit was 16.34 months (range 3-28; SD 6.92). Thirty-nine (56%) of the 70 patients who answered said that the operation had cured their incontinence, 16 (23%) had an improvement in their symptoms, 7 (10%) had worsening of their symptoms and 8 (11%) felt that the operation did not make any difference. The overall success rate according to the patients' perspective was 79%, whereas our audit showed an overall success rate of 86% (77% and 82%, respectively, when we compared only the 66 patients who had both notes and replies available for analysis). CONCLUSION: Although a patient's perception regarding the success of TVT tends to differ from that of a clinician, it was not found to be statistically significant (P = 0.22, McNemar test). The TVT is a very successful operation, but realistic cure rates should be offered to patients.     

女性压力性尿失禁的微创治疗

目的探讨女性压力性尿失禁的发病机制和微创治疗方法。方法女性压力性尿失禁患者25例,经临床、尿动力学检查或膀胱尿道造影确诊,均为稳定性膀胱,无膀胱出口梗阻。采用无张力阴道吊带术(TVT),将吊带无张力置于尿道中段。结果手术时间平均(40±5)min;术中出血量平均(43±10)mL;术后平均留置导尿1.5 d;术后平均住院3 d。23例患者术后尿失禁症状均消失,其中2例患者术后出现尿潴留,留置导尿1周后好转,尿潴留症状消失,尿失禁未复发;2例尿失禁症状显著改善。结论TVT等微创术式因简单、微创、疗效好、并发症少等,目前是女性压力性尿失禁外科手术治疗的发展方向。     

Tension-free vaginal tape for the treatment of urodynamic stress incontinence with intrinsic sphincteric deficiency

The purpose of this study was to evaluate the outcome of tension-free vaginal tape (TVT) procedure in women with urodynamic stress incontinence diagnosed as having intrinsic sphincteric deficiency (ISD). The combination of a maximal urethral closure pressure <20 cm H₂O and a Valsalva leak point pressure <60 cm H₂O was considered as diagnostic of ISD. Subjects with detrusor overactivity on preoperative urodynamics were excluded. A total of 35 patients with both low closure pressure and leak point pressure were enrolled. Bladder perforation occurred in three (8.6%) cases. Postoperative urinary voiding difficulties occurred in nine (25.7%) women. Two patients underwent surgical detension of the tape, with complete resolution of urinary retention and no relapse of incontinence. Women with postoperative voiding dysfunction had a significantly lower detrusorial pressure at the peak flow on preoperative urodynamics compared to those who voided efficiently after TVT. The mean (range) follow-up time was 12.5 months (3–36). The objective cure rate for stress incontinence was 91.4%. Two of the three (66%) patients in whom the TVT procedure failed had a fixed urethra. De novo urge incontinence was found in five (14.3%) patients.     

应用吊带方法经皮膀胱颈悬吊治疗女性压力性尿失禁

目的：介绍吊带方法经皮膀胱颈悬吊术治疗女性压力性尿失禁的经验。方法：在近膀胱颈水平，阴道前壁与尿道之间隧道状切口内预置两端带有尼龙线的网状聚丙烯片，术中窥镜监视下，应用Vesica穿刺针经皮穿刺行膀胱颈悬吊治疗女性压力性尿失禁19例。结果：随访3－45个月，平均17个月，除1例逼尿肌反射低下排尿稍费力外，18例患者无尿失禁及排尿困难。结论：吊带方法经皮膀胱颈悬吊术治疗女性压力性尿失禁，操作简便，创伤小，恢复快，临床效果满意。     

Cystitis as a correlate of female urinary incontinence

The objectives of the research were to study the association between prevalent urge and stress urinary incontinence (UI) and a history of cystitis in adult females. A cross-section of the adult female population, aged 30–59 years, in the Municipality of Aarhus, Denmark, was studied, using self-reported data based on postal questionnaires. The sample consisted of 3114 women, out of whom 2613 (84%) delivered the information requested. The main outcome measures were period prevalence in 1987 of episodes of UI provoked by physical stress and UI associated with a feeling of urge, prevalence of experience of episodes of cystitis and UI related to cystitis in adult life, and prevalence of relative risks, as indicated by odds ratio (OR), of UI conditional on cystitis experience. Results indicated that the 1987 period prevalences of UI provoked by physical stress and UI associated with a feeling of urge were 15% and 9%, respectively. Forty-five per cent reported a history of cystitis and 10% of UI during episodes of cystitis. Both UI provoked by stress and UI associated with a feeling of urge were significantly correlated to cystitis (OR 2.1, P<0.0001, and 1.8, P<0.0001, respectively) and to UI during episodes of cystitis (OR 7.1, P<0.0001, and 5.7, P<0.0001, respectively). When corrected for the stress aspect, UI being associated with a feeling of urge showed no association of its own to a history of cystitis. However, stress and urge aspects were both correlated to the experience of UI during episodes of cystitis. The prevalence of experience of cystitis increased with increasing number of urologic (per operation OR 2.1, P<0.0001) and gynecologic operations (per operation OR 1.5, P<0.0001), e.g. curretage (per operation OR 1.2, P<0.001), but not with the number of abdominal operations or the number of childbirths. It was concluded that cystitis may be an important component of UI etiology. Stress and not urge UI seems to be the key type related to a history of cystitis in general. The experience of UI during cystitis is connected to both stress and urge UI. A history of cystitis may possibly itself by initiated by surgery.     

经阴道无张力吊带术治疗女性压力性尿失禁的体会

目的探讨经阴道无张力吊带术(TVT)治疗女性压力性尿失禁(SUI)的疗效及安全性。方法对2002年5月至2004年12月施行TVT的114例女性SUI患者资料进行回顾性研究。根据Stamey尿失禁分级系统评价TVT手术的有效性。术后较术前尿失禁等级评分改善2级或2级以上为显著改善,1级为改善,无改善甚至加重为无效。术后尿失禁等级为0~1级为完全控尿,2级为有效控尿,3~4级为无效。评估术前、术后的24h尿垫试验及尿动力学检查结果。并对并发症进行统计和分析。结果随访110例(96.5%),随访时间6~30个月。24h尿垫试验术前(38.3±10.4)g,术后(8.8±7.4)g;尿失禁症状评分从术前42.3±11.4,术后20.4±9.2;尿失禁等级评分显著改善者94例(85.5%),改善者12例(10.9%),无效者4例(3.6%)。术后完全控尿者89例(80.9%),有效控尿者14例(12.7%),无效者7例(6.4%)。术中发生膀胱穿孔2例(1.8%),出血14例(12.7%)。术后1个月内有排尿不畅者9例(8.2%),尿频、尿急者12例(10.9%),尿潴留者1例(0.9%);术后6个月后有耻骨上不适者8例(7.3%),排尿不尽者2例(1.8%),尿频、尿急者3例(2.7%)。1例反复尿潴留患者经保守治疗无效,最终将吊带切断。术后未出现吊带处阴道黏膜糜烂和明显盆腔血肿。结论TVT术是目前治疗女性SUI的一种有效、安全的微创手术。     

中段尿道吊带术治疗女性压力性尿失禁的手术并发症防治

目的探讨中段尿道吊带术的并发症及其防治措施。方法采用中段尿道吊带术治疗女性压力性尿失禁48例,其中,TVT术26例,TVT-O术19例,Sparc术3例。结果手术并发症包括:1例(TVT)术中膀胱镜检发现穿刺针穿入膀胱,经重新调整穿刺纠正。2例(Sparc术和TVT-O术各1例)分别于术后1、3个月发现阴道前壁吊带外露,经再次手术修补阴道前壁治愈。4例出现尿急症状,给予黄酮哌酯对症治疗2周后症状明显改善。2例出现股内侧轻度疼痛,未经特殊治疗,1周内症状自行缓解。结论中段尿道吊带术治疗女性压力性尿失禁方法简便、疗效可靠,但其手术并发症的发生应引起重视。
