RESUMEN

Aims: The aim was to establish an official interdisciplinary guideline, published and coordinated by the German Society of Gynecology and Obstetrics (DGGG). The guideline was developed for use in German-speaking countries. In addition to the Germany Society of Gynecology and Obstetrics, the guideline has also been approved by the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). This is a guideline published and coordinated by the DGGG. The aim is to provide evidence-based recommendations obtained by evaluating the relevant literature for the diagnostic, conservative and surgical treatment of women with female pelvic organ prolapse with or without stress incontinence. Methods: We conducted a systematic review together with a synthesis of data and meta-analyses, where feasible. MEDLINE, Embase, Cinahl, Pedro and the Cochrane Register were searched for relevant articles. Reference lists were hand-searched, as were the abstracts of the Annual Meetings of the International Continence Society and the International Urogynecological Association. We included only abstracts of randomized controlled trials that were presented and discussed in podium sessions. We assessed original data on surgical procedures published since 2008 with a minimum follow-up time of at least 12 months. If the studies included descriptions of perioperative complications, this minimum follow-up period did not apply. Recommendations: The guideline encompasses recommendations for the diagnosis and treatment of female pelvic organ prolapse. Recommendations for anterior, posterior and apical pelvic organ prolapse with or without concomitant stress urinary incontinence, uterine preservation options, and the pros and cons of mesh placements during surgery for pelvic organ prolapse are presented. The recommendations are based on an extensive and systematic review and evaluation of the current literature and include the experiences and specific conditions in Germany, Austria and Switzerland.

RESUMEN

OBJECTIVE: To compare the pelvic floor function of primiparous women to women after a second delivery regarding symptoms of urinary and anal incontinence, anal sphincter ruptures and bladder-neck mobility. METHODS: A questionnaire evaluating symptoms of urinary and anal incontinence was used in nulliparous women before and 27 months after childbirth. Furthermore these symptoms were correlated with functional changes of the pelvic floor based on a careful gynecologic examination as well as perineal and endoanal ultrasound. RESULTS: 112 nulliparous women were included, 49 women returned for follow-up on average 27 months (SD 4.4 months) after the first delivery. 39 women (group A) had just one delivery, 10 women (group B ? 10/49) had had a second delivery. Apart from levator ani muscle strength, no significant difference between pelvic floor function of group A vs group B was demonstrable. Furthermore, we could show no significant difference for symptoms of urinary (11 (28.2%) vs. 5 (50.0%)) and anal incontinence (14 (35.9%) vs. 4 (40.0%)) between both groups. However, we found a lasting increase of stress urinary and anal incontinence as well as overactive bladder symptoms after one or more deliveries. The position of the bladder neck at rest was lower in both groups compared to the position before the first delivery and bladder neck mobility increased after one or more deliveries. DISCUSSION: Our study shows several statistically significant changes of the pelvic floor function even on average 27 months after delivery, but a subsequent delivery did not compromise the pelvic floor any further.

RESUMEN

OBJECTIVE: To compare the function of the pelvic floor in primiparae before and during pregnancy with the status post partum concerning symptoms of incontinence, sphincter ruptures, bladder-neck mobility and the influence of the different modes of deliveries. METHODS: Questionnaire evaluating symptoms of urinary and anal incontinence in nulliparous women before and after delivery and correlating these symptoms with functional changes of the pelvic floor based on a careful gynaecologic examination as well as perineal and endoanal ultrasound. RESULTS: 112 women were included in our study and came for the first visit, 99 women returned for follow-up 6 months after childbirth. Stress and flatus incontinence significantly increased from before pregnancy (3 and 12%) to after childbirth (21 and 28%) in women with spontaneous delivery or vacuum extraction. No new symptoms occurred after c-section. There was no significant difference between the bladder neck position before and after delivery. The mobility of the bladder neck was significantly higher after vaginal delivery using a vacuum extraction compared to spontaneous delivery or c-section. The bladder neck in women with post partum urinary stress incontinence was significantly more mobile than in continent controls. The endoanal ultrasound detected seven occult sphincter defects without any correlation to symptoms of anal incontinence. CONCLUSION: Several statistically significant changes of the pelvic floor after delivery were demonstrated. Spontaneous vaginal delivery or vacuum extraction increases the risk for stress or anal incontinence, delivery with vacuum extraction leads to higher bladder neck mobility and stress incontinent women have more mobile bladder necks than continent women.

RESUMEN

OBJECTIVE: Many surgeons perform an anti-incontinence procedure during prolapse surgery in women in whom occult stress urinary incontinence has been demonstrated. Others prefer a two-step approach. It was the aim of the study to find out how many women really need a second operation and if a positive cough stress test with the prolapse reduced is associated with the development of stress urinary incontinence after prolapse surgery. METHODS: 233 women were operated for primary or recurrent prolapse without complaining of SUI. Preoperatively, 53/233 women had a full urogynecological workup with the prolapse reduced. Postoperatively, if the patient suffered from stress urinary incontinence, an anti-incontinence surgery was performed. RESULTS: 19/53 (35.8%) women who had a stress test with the prolapse reduced before surgery were defined as occult stress incontinent. Only 3 women (15.8%) of these 19 women developed symptoms of incontinence after prolapse surgery and had to be operated because of that. 18/233 (7.7%) complained of SUI 6 weeks to 6 months after surgery and received a TVT-tape. CONCLUSION: The incidence of stress urinary incontinence manifesting after prolapse surgery is low in this study with 7.7%. This fact and the possible severe side effects of an incontinence operation justify a two-step approach if the patient is counseled and agrees. However, there is a small subgroup of women (3/19, 15.8%) with preoperative OSUI and SUI after surgery, who would benefit from a one-step approach. Further research is required to identify these women before surgical intervention.

RESUMEN

Ultrasound is a supplementary, indispensable diagnostic procedure in urogynecology; perineal, introital, and endoanal ultrasound are the most recommended techniques. The position and mobility of the bladder neck can be demonstrated. In patients undergoing diagnostic work-up for urge symptoms, ultrasound occasionally demonstrates urethral diverticula, leiomyomas, and cysts in the vaginal wall. These findings will lead to further diagnostic assessment. The same applies to the demonstration of bladder diverticula, foreign bodies in the bladder, and bullous edema. With endoanal ultrasound, different parts of the sphincter ani muscle can be evaluated. Recommendations for the standardized use of urogenital ultrasound are given.

RESUMEN

OBJECTIVE: To investigate the impact of parameters influencing the duration of the second stage of labor in vaginal deliveries. STUDY DESIGN: 1200 consecutive vaginal deliveries were analyzed. Descriptive statistics are reported for parity, duration of first and second stage of labor, maternal age, birth weight, position of the fetal head, epidural analgesia and oxytocin augmentation. Logistic regression analysis was performed to assess the contribution of different variables to the length of the second stage of labor. RESULTS: The mean length of the second stage was 70 min. In univariate analysis, parity, oxytocin augmentation and epidural analgesia, as well as occipito-posterior presentation were significant parameters associated with a prolonged second stage of labor. No correlation was found for birth weight and maternal age. In multivariate regression analysis, nulliparity and epidural analgesia were the strongest risk factors for a prolonged second stage. CONCLUSIONS: The impact of epidural analgesia on the second stage of labor should be considered in obstetrical management.

RESUMEN

Radiologic procedures such as lateral cystography have been substituted by ultrasound in urogynecology. The techniques are standardized and reproducible. Ultrasound is also useful for evaluating the bladder neck (funneling), the urethra (diverticula) and the paraurethral tissues (vaginal cysts, vaginal fibroids). The technique is limited in patients with genital prolapse beyond the hymenal ring. Advantages include the avoidance of x-rays and catherization.

RESUMEN

The aim of the study was to determine the efficacy of cotrimoxazole administration after urodynamic testing to prevent urinary tract infections. In a single-blind prospective randomized study 94 women who attended for urodynamic evaluation were included. After multichannel urodynamic testing, including two catheterizations, the women received a single dose of cotrimoxazole or placebo. A clean-catch urine specimen was tested for infection after 1 week. Seventy women returned a urine specimen after 1 week: 2/37 (5.4%) in the treatment and 2/33 (6.1%) in the placebo group had acquired a new urinary tract infection after urodynamics. One major and one minor adverse reaction to cotrimoxazole were reported. The power of the sample size was unfortunately too small to draw conclusions as to the efficacy of prophylaxis.

RESUMEN

BACKGROUND: Local recurrence remains a major concern after primary treatment of breast cancer and has a major impact on subsequent survival. While most studies report a poorer survival rate in patients with a local recurrence after mastectomy than after breast conservation, it remains controversial whether different risk profiles at the time of primary diagnosis may account for this difference. METHOD: Matched pair analysis of 134 patients with newly diagnosed locoregional recurrence of breast cancer without evidence of systemic disease. Matching criteria included the primary surgical treatment, tumor size, nodal status, and age. The significance of various prognostic parameters at the time of primary diagnosis and at the time of recurrence were evaluated, by univariate and multivariate analyses, with respect to survival after recurrence. The median follow-up was 8.4 years. RESULTS: Risk factors at the time of presentation, such as tumor size and lymph node status, were comparable between both groups. Local recurrence occurred on an average 9 months earlier in patients after mastectomy (P = 0.08). Univariate analysis showed that lymph node status (P = 0.0001) and disease-free interval from primary treatment to local recurrence (P = 0.0002) were the most significant single prognostic factors for subsequent survival after local recurrence. The primary surgical treatment modality was shown to be of marginal statistical influence (only P = 0.05). CONCLUSION: Local recurrence after mastectomy seems to be associated with worse survival than after breast-conserving therapy. Early onset of chest-wall recurrence, moreover, represents the highest independent risk for cancer-associated death.

RESUMEN

The aim of this study was to describe normal characteristics of spontaneous and voluntary pelvic muscle function in nulliparous healthy continent women and to assess the reaction of the pelvic floor to stress and fatigue. Ten nulliparous volunteers were recruited. Pelvic muscle strength was evaluated by palpation and perineal ultrasound. Kinesiological EMG and perineal ultrasound were performed to test for possible fatigue and to assess bladder neck mobility during coughing with a pre-contraction of the pelvic floor muscles. Bladder neck mobility did not increase after attempts to fatigue the pelvic floor muscles. Bladder neck descent was significantly less when the women were instructed to contract the pelvic floor muscles before coughing. The contraction of the pelvic floor muscles stabilizes the vesical neck in nulliparous women.

RESUMEN

The aim of the study was to evaluate whether four different techniques were able to correctly measure pelvic floor muscle strength only. Sixteen volunteers performed a set of muscle contractions using the pelvic floor muscles (PFM) only, the abdominal muscles with and without PFM, gluteal muscles with and without PFM, adductor muscles with and without PFM and Valsalva maneuver with and without PFM. Pelvic floor muscle strength was evaluated by digital palpation, intravaginal EMG, pressure perineometry and perineal ultrasound. A 'non-pelvic muscle induced' reading was defined as a significant increase even though the pelvic floor muscles were not contracted. Results were as follows: isolated abdominal muscle contraction: non-pelvic muscle induced readings in 3/8 women with EMG and in 3/8 with pressure perineometry; isolated gluteal muscle contraction: non-pelvic muscle induced readings in 1/2 women with EMG perineometry; isolated adductor muscle contraction: non-pelvic muscle induced readings in 6/11 women with EMG perineometry and in 2/11 women with pressure perineometry; Valsalva maneuver: non-pelvic muscle induced readings in 4/9 women with EMG perineometry and 9/9 women with pressure perineometry. It was concluded that EMG and pressure perineometry do not selectively depict pelvic floor muscle activity.

RESUMEN

OBJECTIVE: To evaluate the mobility of the vesical neck during coughing and valsalva in healthy nulliparous volunteers and to test the reliability of the technique applied. DESIGN: Clinical observational study. SETTING: Department of Obstetrics and Gynaecology, Cantonal Hospital Lucerne, Switzerland. POPULATION: Thirty-nine nulliparous volunteers. METHODS: Vesical neck motion was assessed with perineal ultrasound. Intra-abdominal pressure was controlled for with an intrarectal probe. Intra-rater reliability was evaluated. RESULTS: Vesical neck mobility was significantly lower during coughing (8 mm, SD 4 mm) than during valsalva (15 mm, SD 10 mm) (P < 0.005). Between individuals mobility varied from 4 mm to 32 mm during coughing and from 2 mm to 31 mm during valsalva. Test-retest-studies showed a maximum difference between to tests during coughing of 4 mm and during valsalva of 5 mm. CONCLUSION: The bladder neck is mobile in normal continent women and bladder neck mobility is lower during coughing than during Valsalva.

RESUMEN

The conservative treatment of stress or mixed incontinence results in improvement or cure in about 60 % of patients. Pelvic floor muscle training without or with biofeedback, electrical stimulation and vaginal cones are not superior to each other.

RESUMEN

The aim of the study was to evaluate the relationship between Valsalva leak-point pressure (VLPP) and cough leak-point pressure (CLPP). Sixty women with stress urinary incontinence were included. One woman was excluded from evaluation because of detrusor instability. At a bladder volume of 200-300 mL (mean, 284; standard deviation, 29) CLPP and VLPP were measured in the sitting position. Intra-abdominal pressure was recorded with a rectal balloon catheter. A standardized pad test and multi-channel urodynamics were performed. VLPP was significantly lower than CLPP (58.9+/-27.6 versus 112.5+/-46.9 cm H(2)O, P<0.0001). Although CLPP was negative in two women only, VLPP was negative in 24 of 59 women (40.1%). If intrinsic sphincter deficiency was defined as a leak-point pressure of 65 cm H(2)O, 16.9% of women fulfilled this criterion using the CLPP compared to 35.6% if the VLPP is used. In conclusion, coughing and Valsalva seem to result in a different reaction of the pelvic floor.

RESUMEN

INTRODUCTION: Recent studies have renewed an old controversy about the efficacy of adjuvant radiotherapy following mastectomy for breast cancer. Radiotherapy is usually recommended for advanced disease, but whether or not to use it in pT1-T2 pN0 situations is still being debated. This study was designed to clarify whether or not routine radiotherapy of the chest wall following mastectomy reduces the risk of local recurrence and if it influences the overall survival rate. METHODS: Retrospective analysis of patients treated with mastectomy for pT1-T2 pN0 tumors and no systemic treatment. Patients treated with radiotherapy of the chest wall following mastectomy (Group A) are compared with those treated with mastectomy alone (Group B). RESULTS: A total of 918 patients underwent mastectomy. Patients who received adjuvant radiotherapy after mastectomy (n = 114) had a significantly lower risk for local recurrence. Ten years after the primary diagnosis, 98.1% of the patients with radiotherapy were disease free compared to 86.4% of the patients without radiotherapy. The average time interval from primary diagnosis until local recurrence was 8.9 years in Group A and 2.8 years in Group B. The Cox regression analysis including radiotherapy, tumor size and tumor grading found the highest risk for local recurrence for patients without radiotherapy (p < 0.0004). In terms of overall survival however, the Kaplan-Meier analysis showed no difference between the two groups (p = 0.8787) and the Cox regression analysis failed to show any impact on overall survival. CONCLUSION: With observation spanning over 35 years, this study shows that adjuvant radiotherapy of the chest wall following mastectomy reduces the risk for local recurrence in node-negative patients with pT1-T2 tumors but has no impact on the overall survival rate.

RESUMEN

The aim of the study was to evaluate the efficacy of pelvic floor training with EMG-controlled home biofeedback in the treatment of stress and mixed incontinence in women. Subjects were recruited from the urodynamic outpatient clinic and performed pelvic muscle training with an EMG-controlled biofeedback device for 20 minutes daily for 6 months. The number of pads used per day, the number of incontinence and urgency episodes, voiding frequency, maximum urethral closure pressure, functional urethral length and pressure/transmission ratio during stress were assessed before and after treatment. Thirty-three patients (13 with stress and 20 with mixed incontinence) completed the study. There was a significant decrease in the number of pads used per day, the number of incontinence and urgency episodes, and the voiding frequency. Twenty-eight patients (85%) reported that they were cured or improved. Urodynamic parameters did not change significantly. It was concluded that home pelvic floor training with EMG-controlled biofeedback is efficient in 85% of patients in alleviating the symptoms of genuine stress and mixed incontinence without causing side effects.

RESUMEN

OBJECTIVE: To evaluate a new sonographic method to measure depth and width of proximal urethral dilation during coughing and Valsalva maneuver and to report its use in a group of stress-incontinent and continent women. METHODS: Fifty-eight women were evaluated, 30 with and 28 without stress incontinence proven urodynamically, with a bladder volume of 300 mL and the subjects upright. Urethral pressure profiles at rest were performed with a 10 French microtip pressure catheter. Bladder neck dilation and descent were assessed by perineal ultrasound (5 MHz curved linear array transducer) with the help of ultrasound contrast medium (galactose suspension-Echovist-300), whereas abdominal pressure was assessed with an intrarectal balloon catheter. Statistical analysis used the nonparametric Mann-Whitney test. RESULTS: The depth and diameter of urethral dilation could be measured in all women. During Valsalva, all 30 incontinent women exhibited urethral dilation. One incontinent woman showed dilation only while performing a Valsalva maneuver, not during coughing. In the continent group, 12 women presented dilation during Valsalva and six during coughing. In continent women, dilation was visible only in those who were parous. Nulliparous women did not have dilation during Valsalva or coughing. Bladder neck descent was visible in continent and incontinent women. CONCLUSION: This method permits quantification of depth and diameter of bladder neck dilation, showing that both incontinent and continent women might have bladder neck dilation and that urinary continence can be established at different locations along the urethra in different women. Parity seems to be a main prerequisite for a proximal urethral defect with bladder neck dilation.

RESUMEN

OBJECTIVE: To examine the anatomic identity of sonographically visible sphincteric structures of the female urethra. METHODS: The urethra, urinary bladder, and vagina were removed from 11 fresh female cadavers and placed in a water bath. Intraurethral ultrasound was performed with a 360 degrees-rotating 7.5-MHz ultrasound probe. Afterward, the specimens were fixed and cross sections were made transverse to the urethral axis at 5-mm intervals. Corresponding ultrasonograms and histologic images were matched and depicted simultaneously side by side. The anatomic identity of sonographically visible structures was determined by histologic examination and thickness of the longitudinal smooth urethral sphincter measured. RESULTS: Structures visible sonographically were the striated and smooth urethral sphincter muscle layers, vagina, and blood vessels with diameters exceeding 0.2 mm. The longitudinal smooth muscle layer appeared as a well-defined internal hypoechoic ring. The outer circular smooth muscle layers and the striated muscle layers were a more irregular and hyperechoic zone. The circular smooth muscle layers and the striated sphincter muscle layers could not always be differentiated easily. With formalin fixation, tissue shrinkage resulted in a smaller thickness of the longitudinal smooth muscle measured on the histologic specimen. CONCLUSION: With intraurethral ultrasound, the longitudinal smooth muscle layer appears as a well-defined and measurable hypoechoic ring. The region of the circular smooth muscle and the striated muscle emerges as a hyperechoic and less definable outer zone.
