The Burch procedure (1961) was considered the gold standard treatment for stress urinary incontinence (SUI) before the midurethral slings (MUSs) were introduced, in 2001.
This historical perspective of the Burch’s timeline can encourage urogynecological surgeons to master the Burch technique as one of the options for surgical treatment of SUI.
Criteria A bibliographic search was performed in the PubMed and National Library of Medicine (NIH) databases with the terms Burch colposuspension AND history AND stress urinary incontinence in the last 20 years. The original article by Burch (1961) was included. The references were read by three authors. The exclusion criterion was studies in non-English languages. Biomedical Library Special Collections were included as historical relevant search.
Some modifications of the technique have been made since the Burch procedure was first described. The interest in this technique has been increasing due to the negative publicity associated with vaginal synthetic mesh products. Twenty-nine relevant articles were included in the present review article, and numerous trials have compared Burch colposuspension with MUS.
This historical perspective enables the scientific community to review a standardized technique for SUI. Burch colposuspension should be considered an appropriate surgical treatment for women with SUI, and an option in urogynecological training programs worldwide.

To evaluate whether performing preoperative urodynamic study influences postoperative urinary symptoms of women with stress urinary incontinence that underwent transobturator sling.
Retrospective analysis of patients treated for stress urinary incontinence by transobturator sling from August 2011 to October 2018. Predictor variables included preoperative urodynamic study, age, incontinence severity, body mass index, preoperative storage symptoms and previous anti-urinary incontinence procedure. Outcome variables were postoperative subjective continence status, storage symptoms and complications. Logistic regression after propensity score was employed to compare outcomes between patients who underwent or not pre-operative urodynamic study.
The present study included 88 patients with an average follow-up of 269 days. Most patients (n = 52; 59.1%) described storage symptoms other than stress urinary incontinence, and 38 patients (43.2%) underwent preoperative urodynamic studies. Logistic regression after propensity score did not reveal an association between urinary continence outcomes and performance of preoperative urodynamic study (odds ratio 0.57; confidence interval [CI]: 0.11-2.49). Among women that did not undergo urodynamic study, there was a subjective improvement in urinary incontinence in 92% of the cases versus 87% in those that underwent urodynamic study (p = 0.461). Furthermore, postoperative storage symptoms were similar between women who did not undergo urodynamic study and those who underwent urodynamic study, 13.2% versus 18.4%, respectively (p = 0.753).
Preoperative urodynamic study had no impact on urinary incontinence cure outcomes as well as on urinary storage symptoms after the transobturator sling in women with stress urinary incontinence.

To evaluate the long-term subjective cure rate of the transobturator sling, including an analysis of the risk factors and of the impact of increased surgical experience on the results.
A retrospective cohort study of women who underwent transobturator sling surgery from 2005 to 2011 was conducted. Patients were evaluated by a telephone survey using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and by subjective questions regarding satisfaction. An ICIQ-SF score of 0 was considered a cure. The crude and adjusted odds ratios and 95% confidence intervals were estimated in univariate and multivariate logistic regression models to identify risk factors for surgical failure. Differences with p < 0.05 were considered significant.
In total, 152 (70.6%) patients answered the questionnaire. The median follow-up period was 87 months. The urodynamic diagnosis was stress urinary incontinence in 144 patients (94.7%), and mixed urinary incontinence in 8 (5.3%) patients. Complications occurred in 25 (16%) patients. The ICQ-SF results indicated that 99 (65.10%) patients could be considered cured (ICIQ-SF score = 0). Regarding the degree of satisfaction, 101 (66%) considered themselves cured, 43 (28%) considered themselves improved, 7 (4.6%) considered themselves unchanged, and one reported worsening of the incontinence. After the univariate and multivariate analyses, the primary risk factor for surgical failure was the presence of urgency (p < 0.001).
The transobturator sling is effective, with a low rate of complications and a high long-term satisfaction rate. The risk factors for failure were the presence of urgency and patient age. The increased experience of the surgeon was not a factor that influenced the rate of complications.

Purpose: to analyze the prevalence of genuine urinary incontinence (GUI) recurrence, after at least two years of follow-up, in different surgical techniques used for its correction. Patients and Methods: fifty-five patients with diagnosis of GUI, submitted to surgery for its repair at the Serviço de Ginecologia e Obstetrícia do Hospital de Clínicas de Porto Alegre from 1992 to 1996 and whose post-surgical follow-up was superior to 2 years were divided into three groups according to the surgical approach: Kelly-Kennedy (n = 24), Burch (n = 23) and Marshall-Marchetti-Krantz (n = 8). Results: there were no differences regarding recurrence rate, age at surgery and at recurrence time, estrogen therapy, number of pregnancies and vaginal delivery (p>0.05). Although posterior perineoplasty was more prevalent in the Kelly-Kennedy group, it did not influence the recurrence rate. The group submitted to the Burch approach had more years of menopause at the time of surgery. Conclusion: the recurrence rates of urinary incontinence comparing the three different techniques (Kelly-Kennedy, Burch and Marshall-Marchetti-Krantz) were, respectively, 29.2, 39.1 and 50%, which did not differ statistically. Considering the potential confusional bias for urinary stress incontinence, they did not differ among the groups. Nevertheless, we noticed that all women who had previous surgery presented recurrence of incontinence.

PURPOSE: to evaluate and compare results of female pelvic floor surface electromyography in different positions: lying, sitting and standing. METHODS: twenty-six women with the diagnosis of stress urinary incontinence treated with a protocol of exercises to strengthen the pelvic floor muscle were evaluated. Pelvic floor surface electromyography was performed with an intravaginal sensor connected to Myotrac 3G TM equipment, as follows: initial rest of 60 s, five phasic contractions, one 10-s tonic contraction and one 20-s tonic contraction. The amplitudes were obtained from the difference between the final contraction amplitude and the amplitude at rest (in µV). Wilcoxon test was applied for nonparametric data (p value <0.05). RESULTS: the amplitudes of contractions were higher in the lying position, decreasing in the sitting and standing positions. In the lying position, the median values of phasic and tonic contractions were 23.5 (5-73), 18.0 (3-58) and 17.0 (2-48), respectively. In the sitting position, they were 20.0 (2-69), 16.0 (0-58) and 15.5 (1-48). In the standing position they were 16.5 (3-67), 12.5 (2-54) and 13.5 (2-41). All amplitude values were significantly lower in the standing position compared to the lying position (p<0.001, p<0.001 and p=0.003). Similar results were also found in comparison to the sitting position. However, there was no significant difference between the lying and the sitting positions. CONCLUSION: all female pelvic floor contraction amplitudes were lower in the standing position, suggesting that the muscle strength should be intensified in that position.

OBJECTIVE: to compare Baden and Walker's (BW) classification system to the International Continence Society (ICS) standardization of terminology of female pelvic organ prolapse. METHODS: information about urogynecological investigation on 101 women, performed by the Urogynecology and Vaginal Surgery Sector of UNIFESP/EPM, was retrospectively analyzed. Only patients who had undergone the standard ICS exam which quantifies the pelvic prolapse were selected. According to ICS, the prolapse is analyzed through a standard reference system relating the hymen to the anatomic position of six vaginal points: two in the anterior vaginal wall, two in the vaginal apex and other two in the posterior vaginal wall. The maximum amount of pelvic organ prolapse was viewed and recorded during a Valsalva's maneuver. The measurement of the most distal point of the prolapse was performed and it was compared to the BW classification system. The data were analyzed by kappa statistics, to assess the concordance between the two terminologies. RESULTS: There was total correspondence only for the posterior vaginal prolapse stage IV (one patient) and for the uterus prolapse stage 0 (29 patients) with severe rectocele and absence of prolapse, respectively, according to BW. In the three types of prolapses evaluated, the values of kappa statistics were below 0.4, indicating a weak concordance between the two terminologies. There is an extensive variation in the measurement of the most distal point of prolapse when the BW classification is perfomed. CONCLUSIONS: there is a weak concordance between the BW classification system and the ICS standardization of terminology of female pelvic organ prolapse.
