Validation of the pelvic organ prolapse quantification (POP-Q) system in left lateral position

International Urogynecology consultation chapter 2 committee 3: the clinical evaluation of pelvic organ prolapse including investigations into associated morbidity/pelvic floor dysfunction

INTRODUCTION AND HYPOTHESIS

This manuscript from Chapter 2 of the International Urogynecology Consultation (IUC) on Pelvic Organ Prolapse (POP) reviews the literature involving the clinical evaluation of a patient with POP and associated bladder and bowel dysfunction.

METHODS

An international group of 11 clinicians performed a search of the literature using pre-specified search MESH terms in PubMed and Embase databases (January 2000 to August 2020). Publications were eliminated if not relevant to the clinical evaluation of patients or did not include clear definitions of POP. The titles and abstracts were reviewed using the Covidence database to determine whether they met the inclusion criteria. The manuscripts were reviewed for suitability using the Specialist Unit for Review Evidence checklists. The data from full-text manuscripts were extracted and then reviewed.

RESULTS

The search strategy found 11,242 abstracts, of which 220 articles were used to inform this narrative review. The main themes of this manuscript were the clinical examination, and the evaluation of comorbid conditions including the urinary tract (LUTS), gastrointestinal tract (GIT), pain, and sexual function. The physical examination of patients with pelvic organ prolapse (POP) should include a reproducible method of describing and quantifying the degree of POP and only the Pelvic Organ Quantification (POP-Q) system or the Simplified Pelvic Organ Prolapse Quantification (S-POP) system have enough reproducibility to be recommended. POP examination should be done with an empty bladder and patients can be supine but should be upright if the prolapse cannot be reproduced. No other parameters of the examination aid in describing and quantifying POP. Post-void residual urine volume >100 ml is commonly used to assess for voiding difficulty. Prolapse reduction can be used to predict the possibility of postoperative persistence of voiding difficulty. There is no benefit of urodynamic testing for assessment of detrusor overactivity as it does not change the management. In women with POP and stress urinary incontinence (SUI), the cough stress test should be performed with a bladder volume of at least 200 ml and with the prolapse reduced either with a speculum or by a pessary. The urodynamic assessment only changes management when SUI and voiding dysfunction co-exist. Demonstration of preoperative occult SUI has a positive predictive value for de novo SUI of 40% but most useful is its absence, which has a negative predictive value of 91%. The routine addition of radiographic or physiological testing of the GIT currently has no additional value for a physical examination. In subjects with GIT symptoms further radiological but not physiological testing appears to aid in diagnosing enteroceles, sigmoidoceles, and intussusception, but there are no data on how this affects outcomes. There were no articles in the search on the evaluation of the co-morbid conditions of pain or sexual dysfunction in women with POP.

CONCLUSIONS

The clinical pelvic examination remains the central tool for evaluation of POP and a system such as the POP-Q or S-POP should be used to describe and quantify. The value of investigation for urinary tract dysfunction was discussed and findings presented. The routine addition of GI radiographic or physiological testing is currently not recommended. There are no data on the role of the routine assessment of pain or sexual function, and this area needs more study. Imaging studies alone cannot replace clinical examination for the assessment of POP.

The Sims position and the Sims vaginal speculum, re-examined

INTRODUCTION AND HYPOTHESIS

American gynecologist J. Marion Sims (1813-1883) is known for developing the first consistently successful operation for the repair of vesico-vaginal fistula, for inventing the Sims vaginal speculum, and for popularizing the left lateral decubitus position for gynecological examination and treatment.

METHODS AND RESULTS

This article reviews the history of the Sims vaginal speculum, charting its evolution from a bent pewter spoon to the lever speculum and finally to its now-familiar form as the two-bladed Sims speculum.

CONCLUSION

The article also reviews the origins of the Sims position, correcting popular misconceptions concerning both the position and the speculum and advocating for greater familiarity with the use of both of these valuable tools by practicing clinicians.

Post-hysterectomy vaginal vault prolapse

Post-hysterectomy vaginal vault prolapse (PHVP) is a recognised although rare complication following both abdominal and vaginal hysterectomy and the risk is increased in women following vaginal surgery for urogenital prolapse. The management of PHVP remains challenging and whilst many women will initially benefit from conservative measures, the majority will ultimately require surgery. The purpose of this paper is to review the prevalence and risk factors associated with PHVP as well to give an overview of the clinical management of this often complicated problem. The role of prophylactic primary prevention procedures at the time of hysterectomy will be discussed as well as initial conservative management. Surgery, however, remains integral in managing these complex patients and the vaginal and abdominal approach to managing PHVP will be reviewed in detail, in addition to both laparoscopic and robotic approaches.

Interobserver agreement of multicompartment ultrasound in the assessment of pelvic floor anatomy

OBJECTIVE

To assess the interobserver agreement of pelvic floor anatomical measurements using multicompartment pelvic floor ultrasound.

METHODS

Females were recruited from the urogynaecology/gynaecology clinics between July and October 2009 and underwent multicompartment pelvic floor ultrasonography (PFUS) using two-dimensional (2D) transperineal ultrasound (TPUS), high-frequency 2D/three-dimensional (3D) endovaginal ultrasound (EVUS) using a biplane probe with linear and transverse arrays and a 360° rotational 3D-EVUS. PFUS measurements were independently analysed by two clinicians.

RESULTS

158 females had PFUS assessment. Good-to-excellent interobserver agreement was observed for bladder-symphysis distance at rest and valsalva, urethral thickness, urethral length, urethral volume, levator hiatus area and width, anteroposterior diameter and anorectal angle. Lins Correlation was used to calculate the interobserver agreement and Bland-Altman plots were created to demonstrate the agreement between the researchers. There was also a good-to-excellent agreement between the two clinicians for the assessment of pelvic organ prolapse (POP) in the anterior, middle and posterior compartment.

CONCLUSION

Multicompartment PFUS is a reliable tool in the anatomical assessment of pelvic floor measurements and POP.

ADVANCES IN KNOWLEDGE

We found a good-to-excellent agreement between the two assessors in the assessment of pelvic floor measurements for all three pelvic floor compartments and suggest that multicompartment PFUS could be considered as a systematic integrated approach to assess the pelvic floor.

The FIGO assessment scoring system (FASS): a new holistic classification tool to assess women with pelvic floor dysfunction: validity and reliability

INTRODUCTION AND HYPOTHESIS

The aim of our study was to assess the interobserver and intraobserver reliability as well as the content and construct validity of the FIGO prolapse assessment scoring system (FASS).

METHODS

Women with and without (controls) symptoms of pelvic organ prolapse (POP) attending gynaecology outpatient clinics in four different countries were recruited prospectively. Each woman was assessed using the FASS which included: (1) physical examination findings designated with the letter P; (2) presence of symptoms of prolapse, urinary and bowel symptoms designated with the letter S; and (3) assessment of degree of bother designated with the letter B. A scoring system was also developed. For interobserver reliability women were examined by two separate examiners using the FASS. For intraobserver reliability the FASS was repeated by the same examiner within 2 weeks. The interclass correlation coefficient (ICC) was also calculated to assess limits of agreements. Validity was assessed by comparing the FASS scores between symptomatic and asymptomatic women using the Mann-Whitney U test (p value <0.001).

RESULTS

A total of 177 women (98 symptomatic and 79 controls) were recruited. Intraobserver reliability had ICCs between 0.716 and 1. Interobserver reliability had ICCs between 0.795 and 0.909. Domain and total scores were significantly different between symptomatic and asymptomatic women (p < 0.001, Mann-Whitney U test). There was a good correlation between FASS P scores and POP-Q scores (rho 0.763, p < 0.001).

CONCLUSIONS

The FIGO prolapse assessment scoring system has good intraobserver and interobserver agreement and has demonstrated both content and construct validity.

Clinical observation of a modified surgical method: posterior vaginal mesh suspension of female rectocele with intractable constipation

STUDY OBJECTIVE

To explore the feasibility and effectiveness of a modified posterior vaginal mesh suspension method in treating female rectocele with intractable constipation.

DESIGN

Descriptive study (Canadian Task Force classification II-3).

SETTING

The study was performed in the Study Center for Female Pelvic Dysfunction Disease, Department of Obstetrics and Gynecology, Tongji Hospital, Tongji University School of Medicine, Shanghai, China. The Study Center includes 15 physicians, most of whom have received advanced training in pelvic floor dysfunctional disease and can skillfully perform many types of operations in patients with such disease. Almost 1500 operations to treat pelvic floor dysfunctional disease are performed every year at the center.

PATIENTS

Thirty-six women with rectocele with intractable constipation.

INTERVENTION

Posterior vaginal mesh suspension.

MEASUREMENTS AND MAIN RESULTS

All patients were followed up for 15 to 36 months. In 29 patients, the condition was cured completely; in 5 patients it had improved; and in 2 patients, the intervention had no effect. Insofar as recovery and improved results, the overall effectiveness rate was 94.4%.

CONCLUSION

Posterior vaginal mesh suspension is an effective, harmless, and convenient method for treatment of female rectocele with intractable constipation. It has positive short-term curative effects, with few complications and sequelae. However, the long-term effects of posterior vaginal mesh suspension should be evaluated.

Pelvic organ support, symptoms and quality of life during pregnancy: a prospective study

INTRODUCTION AND HYPOTHESIS

Prevalence studies show an increase in lower urinary tract and pelvic floor symptoms during pregnancy. The aim of our prospective study was to evaluate changes in pelvic organ support, pelvic floor symptoms and their effect on quality of life (QOL) during the first pregnancy using validated measures. We hypothesised that pregnancy is associated with worsening of pelvic floor function.

METHODS

Objective assessment of pelvic organ support using the Pelvic Organ Prolapse Quantification (POP-Q) system and subjective evaluation of symptoms of pelvic floor disorders and related QOL with the electronic Personal Assessment Questionnaire-Pelvic Floor (ePAQ-PF) were performed in the second trimester and then repeated at 36 weeks gestation.

RESULTS

A total of 182 nulliparae attended the first visit at 20 weeks and 150 (82.4%) women returned for follow-up at 36 weeks gestation. There were no significant changes in POP-Q points or stage between the two visits except for a significant increase in genital hiatus (p = 0.0001) and perineal body length (p = 0.0001). The vaginal symptoms did not show any changes. Symptoms and bother with voiding difficulties and stress urinary incontinence increased during pregnancy. Constipation (p = 0.02) and evacuation subdomains improved significantly (p = 0.009). In the sexual domain, the only subdomain that worsened significantly (p = 0.03) was "sex and vaginal symptoms". None of the pelvic floor symptoms impacted the QOL.

CONCLUSIONS

In our group of nulliparae, pelvic floor-related QOL and prolapse stage did not change significantly from the second to the third trimester of pregnancy.

Effect of childbirth on pelvic organ support and quality of life: a longitudinal cohort study

INTRODUCTION AND HYPOTHESIS

Although childbirth is known to be a major risk factor for pelvic floor disorders, there is a paucity of prospective, long-term data addressing this issue. The aim of our study was to evaluate the changes of pelvic organ support, symptoms and quality of life (QOL) after childbirth.

METHODS

Pelvic organ support was objectively assessed using the Pelvic Organ Prolapse Quantification method (POP-Q) and pelvic floor symptoms were subjectively evaluated using a validated questionnaire performed in the second trimester, 14 weeks, 1 and 5 years after delivery.

RESULTS

We recruited 182 nulliparae and 97 (53.3 %) returned for follow-up at 5 years. POP-Q stage after vaginal delivery (VD) worsened at all time points. After caesarean the worsening in POP-Q stage was temporary at 14 weeks. Prolapse symptoms worsened at 14 weeks (p<0.001) and 1 year (p=0.006) after VD but not at 5 years. No changes in prolapse symptoms occurred after caesarean. Significant increase in faecal incontinence was observed in both delivery groups 5 years after delivery. For all pelvic floor disorder domains there were no significant changes in QOL irrespective of mode of delivery, except for worsening in general sexual QOL after VD.

CONCLUSIONS

Five years after childbirth the stage of prolapse worsened after VD but not after caesarean. However, there was no impact on prolapse symptoms or QOL. After VD women were more likely to experience a worsening in general sex score, but no other difference in QOL measures.
