Levator ani defects and the severity of symptoms in women with anterior compartment pelvic organ prolapse

Introduction and hypothesis

The aims of this study were to evaluate the prevalence of levator ani muscle (LAM) avulsions in a selected cohort of patients with primary anterior compartment pelvic organ prolapse (POP) and to assess whether LAM avulsions, as an independent factor, affect the degree of POP symptoms and sexual dysfunction. Additionally, clinical and demographic variables of women with and those without avulsions were compared.

Methods

We carried out a cross-sectional analysis of a prospective cohort study including 197 women scheduled for anterior compartment POP surgery. LAM avulsions were diagnosed on transperineal 4D ultrasound. Preoperative symptom severity and sexual dysfunction were evaluated using validated questionnaires (Pelvic Floor Disability Index [PFDI-20] and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-Short Form 12 [PISQ-12]). Linear regression was performed with avulsion as the main independent variable against total PFDI-20 and domain scores, bulge symptoms, and PISQ-12 score. Clinical and demographic variables for women with and without avulsions were compared using independent samples t test, Mann–Whitney U test or Chi-squared test.

Results

The prevalence of LAM avulsions was 50.3%. Avulsions were not associated with symptom severity or sexual dysfunction. “Chronic disease causing pain, fatigue or increased intra-abdominal pressure” was the only independent factor associated with all domains of the PFDI-20. Women with avulsions were younger at presentation, older at their first delivery, had lower BMI, and more often had a history of forceps delivery (p < 0.01).

Conclusions

LAM avulsions were highly prevalent in this preoperative POP cohort. Avulsions were not associated with the severity of POP symptoms or sexual dysfunction. Women with avulsions seem to require fewer additional cofactors for developing POP.

     

Site-specific colporrhaphy in posterior compartment pelvic organ prolapse

Introduction and hypothesis

A posterior vaginal wall prolapse is the result of specific tears in the rectovaginal fascia. The prevalence of the different defect types (superior, inferior, overstretching) is unknown, as is the subjective results after operation according to defect type. The aims of this retrospective study were to investigate the prevalence of the different injury sites and the subjective effects after an operation concerning the symptomatic feeling of a vaginal bulge and urinary incontinence in relation to defect types.

Methods

Medical case records and data from the national Danish urogynecological database in patients with a prolapse operation including posterior vaginal wall prolapse for a 6-year period were reviewed. Four hundred and five patients were included. Patients completed the International Consultation on Incontinence-Urinary Incontinence Short Form and three questions on vaginal prolapse symptoms before and 3 months postoperatively.

Results

The majority of women suffered from a superior defect (77 %). There was a statistically significant improvement in prolapse symptoms after surgery, with no difference between patients with different defect types. Patients with a superior defect and overstretching also experienced a statistically significant improvement in urinary incontinence.

Conclusions

The superior defect was the most common defect in the rectovaginal fascia. Patients experienced an improvement in subjective prolapse symptoms concerning the feeling of a vaginal bulge with no difference regarding defect type. Patients with a superior defect or overstretching experienced a statistically significant improvement in urinary incontinence. Similar results were found whether or not concomitant prolapse operations were performed in other compartments.

     

Surgical management of pelvic organ prolapse in women: a short version Cochrane review

BACKGROUND: Pelvic organ prolapse may occur in up to 50% of parous women. A variety of urinary, bowel and sexual symptoms may be associated with prolapse. OBJECTIVES: To determine the effects of the many different surgeries in the management of pelvic organ prolapse. SEARCH STRATEGY: We searched the Cochrane Incontinence Group Specialised Trials Register (searched 3 May 2006) and reference lists of relevant articles. We also contacted researchers in the field. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials that included surgical operations for pelvic organ prolapse. DATA COLLECTION AND ANALYSIS: Trials were assessed and data extracted independently by two reviewers. Six investigators were contacted for additional information with five responding. MAIN RESULTS: Twenty two randomised controlled trials were identified evaluating 2368 women.Abdominal sacral colpopexy was better than vaginal sacrospinous colpopexy in terms of a lower rate of recurrent vault prolapse (RR 0.23, 95% CI 0.07 to 0.77) and less dyspareunia (RR 0.39, 95% CI 0.18 to 0.86), but the trend towards a lower re-operation rate for prolapse following abdominal sacrocolpopexy was not statistically significant (RR 0.46, 95% CI 0.19 to 1.11). However, the vaginal sacrospinous colpopexy was quicker and cheaper to perform and women had an earlier return to activities of daily living. The data were too few to evaluate other clinical outcomes and adverse events. The three trials contributing to this comparison were clinically heterogeneous. For the anterior vaginal wall prolapse, standard anterior repair was associated with more recurrent cystoceles than when supplemented by polyglactin mesh inlay (RR 1.39, 95% CI 1.02 to 1.90) or porcine dermis mesh inlay (RR 2.72, 95% CI 1.20 to 6.14), but data on morbidity, other clinical outcomes and for other mesh or graft materials were too few for reliable comparisons. For posterior vaginal wall prolapse, the vaginal approach was associated with a lower rate of recurrent rectocele and/or enterocele than the transanal approach (RR 0.24, 95% CI 0.09 to 0.64), although there was a higher blood loss and postoperative narcotic use. However, data on the effect of surgery on bowel symptoms and the use of polyglactin mesh inlay or porcine small intestine graft inlay on the risk of recurrent rectocele were insufficient for meta-analysis.Meta-analysis on the impact of pelvic organ prolapse surgery on continence issues was limited and inconclusive, although about 10% of women developed new urinary symptoms after surgery. Although the addition of tension-free vaginal tape to endopelvic fascia plication (RR 5.5, 95% CI 1.36 to 22.32) and Burch colposuspension to abdominal sacrocolpopexy (RR 2.13, 95% CI 1.39 to 3.24) were followed by a lower risk of women developing new postoperative stress incontinence, but other outcomes, particularly economic, remain to be evaluated. AUTHORS' CONCLUSIONS: Abdominal sacrocolpopexy is associated with a lower rate of recurrent vault prolapse and dyspareunia than the vaginal sacrospinous colpopexy. These benefits must be balanced against a longer operating time, longer time to return to activities of daily living and increased cost of the abdominal approach. The use of mesh or graft inlays at the time of anterior vaginal wall repair may reduce the risk of recurrent cystocele. Posterior vaginal wall repair may be better than transanal repair in the management of rectoceles in terms of recurrence of prolapse. The addition of a continence procedure to a prolapse repair operation may reduce the incidence of postoperative urinary incontinence but this benefit needs to be balanced against possible differences in costs and adverse effects. Adequately powered randomised controlled clinical trials are urgently needed.     

Surgical management of pelvic organ prolapse in women: the updated summary version Cochrane review

Introduction and hypothesis  

A previous version of the Cochrane review for prolapse surgery in 2008 provided two conclusions: abdominal sacrocolpopexy had lower recurrent vault prolapse rates than sacrospinous colpopexy but this was balanced against a longer time to return to activities of daily life. An additional continence procedure at the time of prolapse surgery might be beneficial in reducing post-operative stress urinary incontinence; however, this was weighed against potential adverse effects. The aim of this review is to provide an updated summary version of the current Cochrane review on the surgical management of pelvic organ prolapse.     

Pessary treatment for pelvic organ prolapse and health-related quality of life: a review

Pessaries have been used to treat women with pelvic organ prolapse (POP) since the beginning of recorded history. This review aims to assess the effect of pessary treatment on the disease-specific, health-related quality of life in women with pelvic organ prolapse. After a Medline search using the Mesh term ‘pessary’ and critical appraisal, 41 articles were selected and used in this review. Pessaries are widely used to treat pelvic organ prolapse. It is minimally invasive and appears to be safe. Although there is evidence that the use of pessaries in the treatment of pelvic organ prolapse is effective in alleviating symptoms and that patient satisfaction is high, the follow-up in many published papers is short, and the use of validated urogynaecological questionnaires is limited. Comparison with surgical treatment of pelvic organ prolapse is rare and not assessed in a randomised controlled trial.     

Female pelvic organ prolapse using pessaries: systematic review

Introduction and hypothesis

The purpose of this systematic review is to assess the impact of pessary use on the quality of life of women with pelvic organ prolapse, and to determine the satisfaction rate and rationale for discontinuation.

Methods

This review is recorded in the PROSPERO database under number CRD42015023384. The criteria for inclusion were observational study; cross section; cohort study; randomized controlled trial; study published in English, Portuguese, and Spanish; and study whose participants are women with female pelvic organ prolapse treated using a pessary. We did not include limitations on the year of publication. The criteria for exclusion included studies that did not include the topic, bibliographic or systematic reviews and articles that did not use validated questionnaires. The MeSH terms were “Pelvic Organ Prolapse AND Pessaries AND Quality of Life” OR “Pessary AND Quality of Life” OR “Pessaries”.

Results

We found 89 articles. After the final analyses, seven articles were included. All articles associated pessary use with improved quality of life, and all used only validated questionnaires. Over half of the women continued using the pessary during the follow-up with acceptable levels of satisfaction. The main rationales for discontinuation were discomfort, pain in the area, and expulsion of the device.

Conclusion

This systematic review demonstrates that the pessary can produce a positive effect on women’s quality of life and can significantly improve sexual function and body perception.

     

Histology of the vaginal wall in women with pelvic organ prolapse: a literature review

Introduction and hypothesis

The pathophysiology of pelvic organ prolapse (POP) is incompletely understood. The purpose of this study is to describe the current knowledge about histology of the vaginal wall and its possible involvement in the pathogenesis of pelvic organ prolapse.

Methods

Eligible studies were selected through a MEDLINE search covering January 1986 to December 2012. The research was limited to English-language publications.

Results

Investigations of changes in the vaginal tissue that occur in women with genital prolapse are currently still limited and produced contrary results. The heterogeneity of the patients and the control groups in terms of age, parity and hormonal status, of the localization of biopsies and the histological methods as well as the lack of validation of the quantification procedures do not allow clear and definitive conclusions to be drawn.

Conclusions

This review shows that current knowledge of the histological changes observed in women with POP are inconclusive and relatively limited. More studies are needed in this specific field to better understand the mechanisms that lead to POP.     

Primary treatment of pelvic organ prolapse: pessary use versus prolapse surgery

Introduction and hypothesis

The objective of this study was to compare the functional outcomes after pessary treatment and after prolapse surgery as primary treatments for pelvic organ prolapse (POP).

Methods

This was a prospective cohort study performed in a Dutch teaching hospital in women with symptomatic POP of stage II or higher requiring treatment. Patients were treated according to their preference with a pessary or prolapse surgery. The primary endpoint was disease-specific quality of life at 12 months follow-up according to the prolapse domain of the Urogenital Distress Inventory (UDI) questionnaire. Secondary outcomes included adverse events and additional interventions. To show a difference of ten points in the primary outcome, we needed to randomize 80 women (power 80%, α 0.05, taking 10% attrition into account).

Results

We included 113 women (74 in the pessary group, 39 in the surgery group). After 12 months, the median prolapse domain score was 0 (10th to 90th percentile 0–33) in the pessary group and 0 (10th to 90th percentile 0–0) in the surgery group (p < 0.01). Differences in other domain scores were not statistically significant. In the pessary group, 28% (21/74) of the women had a surgical intervention versus 3% (1/39) reoperations in the surgery group (p = 0.01).

Conclusions

In women with POP of stage II or higher undergoing surgery, prolapse symptoms were less severe than in those who were treated with a pessary, but 72% of women who were treated with a pessary did not opt for surgery. Trial registration number: Dutch trial register NTR2856.

     

Porcine dermis interposition graft for repair of high grade anterior compartment defects with or without concomitant pelvic organ prolapse procedures

PURPOSE: Recent literature suggests that graft interposition may decrease the incidence of cystocele recurrence. We describe our experience with porcine dermis interposition grafts for the repair of high grade cystoceles. MATERIALS AND METHODS: We retrospectively reviewed the charts of all women who underwent surgical repair of high grade cystocele. Prolapse was graded with the Baden-Walker and Pelvic Organ Prolapse Quantitation systems, and all patients were evaluated with multichannel videourodynamics. Concomitant stress urinary incontinence was corrected with a pubovaginal sling and vault prolapse was corrected with iliococcygeus vault suspension. Postoperatively patients were evaluated at 2 weeks, 2 months, 6 months and annually thereafter. RESULTS: A total of 70 patients underwent cystocele repair with a porcine dermis interposition graft. Concomitant procedures included a pubovaginal sling in 65 patients and vaginal vault suspension in 50. Mean followup was 24 months. There were no intraoperative complications. Of the patient 59 (91%) are currently dry. One patient had recurrent vault prolapse without cystocele (C -2), which was successfully repaired with abdominal sacral colpopexy. Six patients (8.6%) experienced recurrent grade II (Ba 0) cystocele but continued to be asymptomatic. Three others (4.3%) had recurrence of grade III (Ba +2) cystocele and elected not to undergo reoperation. Two of 6 de novo rectoceles (grade II, Ap and -1 and Bp 0) were repaired with site specific repairs. Superficial vaginal wound separation in 1 case was successfully treated conservatively. CONCLUSIONS: In cases of high grade cystocele interposition of porcine dermis represents a successful and safe treatment option. Cystocele recurrence is typically low grade and it frequently may not require additional surgery.     

Abdominal mesh sacrocolpopexy for recurrent triple‐compartment pelvic organ prolapse

OBJECTIVE

To report the short‐ and intermediate‐ term outcome of safety and efficacy after abdominal‐mesh sacrocolpopexy (MSC) for recurrent anterior, posterior and vault (‘triple‐compartment’) pelvic organ prolapse (POP).

PATIENTS AND METHODS

In a database review we identified non‐neurogenic women who had MSC for recurrent triple‐compartment POP and with a ≥6‐month cystographic follow‐up. The preoperative evaluation included a history, physical examination, Urogenital Distress Inventory (UDI‐6) and visual analogue quality‐of‐life (QoL) questionnaires, urodynamic studies, and a standing lateral voiding cysto‐urethrogram (VCUG) with rest‐strain views. All surgery as performed by the same surgeon, using polypropylene (Marlex) mesh. Perioperative data, the VCUG at 6 months, and interval pelvic examinations were recorded.

RESULTS

Between 2000 and 2006, 29 postmenopausal women (Caucasian, mean age 64 years, sd 11) underwent MSC. The mean (sd , range) operative duration was 228 (75, 170–340) min, the estimated blood loss 150 (100) mL and the inpatient stay 3 (1) days. At a mean (sd ) follow‐up of 23 (16) months, the physical examination showed no evidence of POP of grade ≥2, with mean POP‐Quantification scores of ?2.8 (0.4), ?2.9 (0.4) and ?9.3 (0.8) for points A_a, A_p and C, respectively. Two patients (8%) had evidence of grade ≥2 cystocele at the 6‐month VCUG. After MSC, four of the six UDI and the QoL scores were significantly lower at the last follow‐up than at baseline, with no change in sexual or defecatory function.

CONCLUSIONS

The objective and subjective improvement at the short and intermediate follow‐up after MSC suggest that this is a safe and effective treatment for recurrent triple‐compartment POP.     

Sexual function in women with pelvic organ prolapse compared to women without pelvic organ prolapse

PURPOSE: We compared sexual function in women with pelvic organ prolapse to that in women without prolapse. MATERIALS AND METHODS: We collected sexual function data using a standardized, validated, condition specific questionnaire. The study group consisted of 30 women with pelvic organ prolapse and it was compared with 30 unmatched controls without evidence of prolapse. RESULTS: The 2 groups were similar in age, race, parity and postmenopausal hormone use. Subjects in the study group were more likely to have undergone previous pelvic surgery. Mean total Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire scores +/- SD were lower in the study group compared with controls (81.4 +/- 7.3 vs 106.4 +/- 15.5, p <0.001). In the study group total questionnaire scores in women with prior pelvic surgery were similar to those in women without prior pelvic surgery (79.3 +/- 14.9 vs 82.9 +/- 10.2, p = 0.61). CONCLUSIONS: Pelvic organ prolapse appears to have a significant negative impact on sexual function.     

Surgical strategies for women with pelvic organ prolapse and urinary stress incontinence

Introduction and hypothesis  

This study aims to compare the result of an incontinence procedure performed at the time of prolapse repair or 3 months later in women with pelvic organ prolapse (POP) and stress urinary incontinence (SUI).     

Surgical management of pelvic organ prolapse and uterine descent in the Netherlands

Introduction and hypothesis

To evaluate current practice in the surgical treatment of uterine descent among members of the Dutch Urogynecological Society and to analyze possible trends in the surgical treatment of pelvic organ prolapse in the Netherlands during the last decade.

Methods

A questionnaire, including case scenarios, was sent to the members of the Dutch Urogynecological Society. Using a nationwide registry from the Netherlands, we assessed the number and type of surgical procedures performed for pelvic organ prolapse between 1997 and 2009.

Results

The response rate was 73%, with 161 questionnaires completed. Vaginal hysterectomy, sacrospinous hysteropexy, and the Manchester Fothergill procedure were the most frequently performed surgical interventions for uterine descent. In the case of lower stage uterine descent, uterus preservation was preferred, but in the case of higher stage there was wide variation. Two thirds of the respondents stated that in recent years they tended to save the uterus more often. The registered number of hospital admissions for uterine descent increased by 30% between 1997 and 2009 and the number of surgical procedures almost doubled. The number of vaginal hysterectomies performed because of uterine descent increased by only 15% in this period.

Conclusions

In the Netherlands, surgical policy in the case of uterine descent is very variable, with no clear preference for either hysterectomy or uterus preservation. There was a high increase in hospital admissions and pelvic organ prolapse procedures in the last decade. The number of vaginal hysterectomies performed because of uterine descent did not follow this change, which reflects a trend toward preserving the uterus.
