Short-term Impact of Tension-free Vaginal Tape Obturator Procedure on Sexual Function in Women with Stress Urinary Incontinence

Impact of female stress urinary incontinence and related treatments on the sexual function of male partners: a systematic review and meta-analysis

BACKGROUND

No conclusions have been reached on whether female stress urinary incontinence (SUI) and related treatments affect male partners' sexual function.

AIM

To assess the effects of female SUI and related treatments on male partners' sexual function.

METHODS

A comprehensive search of the PubMed, Embase, Web of Science, Cochrane, and Scopus databases was performed up to September 6, 2022. Studies were included that investigated the effect of female SUI and related treatments on male partners' sexual function.

OUTCOME

Male partners' sexual function.

RESULTS

Of the 2294 citations identified, 18 studies with 1350 participants were included. Two studies assessed the effect of female SUI without treatment on male partners' sexual function, finding that partners had more erectile dysfunction, more sexual dissatisfaction, and less sexual frequency than partners of women without urinary incontinence. Seven studies directly assessed the effect of female SUI treatments on male partners' sexual function by surveying the male partners. Among these, 4 assessed transobturator suburethral tape (TOT) surgery; 1 assessed TOT and tension-free vaginal tape obturator surgery; and the remaining 2 assessed pulsed magnetic stimulation and laser treatment. Among the 4 TOT studies, 3 used the International Index of Erectile Function (IIEF). TOT surgery significantly improved the total IIEF score (mean difference [MD] = 9.74, P < .00001), along with erectile function (MD = 1.49, P < .00001), orgasmic function (MD = 0.35, P = .001), sexual desire (MD = 2.08, P < .00001), intercourse satisfaction (MD = 2.36, P < .00001), and overall satisfaction (MD = 3.46, P < .00001). However, the improvements in IIEF items may be of unclear clinical significance, as 4 points in the erectile function domain of the IIEF are typically defined as the minimal clinically important difference. In addition, 9 studies indirectly assessed the effect of female SUI surgery on male partners' sexual function by surveying patients with the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire. The results demonstrated no significant differences in erectile function (MD = 0.08, P = .40) or premature ejaculation (MD = 0.07, P = .54).

CLINICAL IMPLICATIONS

The effects of female SUI and related treatments on male partners' sexual function were summarized for the first time, providing a reference for future clinical practice and scientific research.

STRENGTHS AND LIMITATIONS

A limited number of studies that used various scales met the standardized eligibility criteria.

CONCLUSION

Female SUI may affect male partners' sexual function, and female patients' anti-incontinence surgery does not appear to have a clinically significant improvement on the sexual function of their partners.

The prostate in women: an updated histological and immunohistochemical profile of the female periurethral glands and their relationship to an implanted midurethral sling

BACKGROUND

There is evidence of glandular tissue in the region of the anterior vaginal wall-female periurethral tissue (AVW-FPT) that has similar morphology and immunohistochemistry to the prostate in men. Surgical injury to this tissue has been suggested as a potential cause of sexual dysfunction following midurethral sling (MUS) procedures. However, the anatomy and embryology of these glands have not been fully resolved. This has led to difficulties in classifying this tissue as a prostate and defining its clinical significance related to MUS procedures.

AIM

To describe the histological and immunohistochemical characteristics of the female periurethral glands using markers of prostate tissue and innervation and to examine their anatomical relationships to an implanted MUS.

METHODS

Using gross and fine dissection, the AVW-FPT was dissected from 9 cadavers. Prior to dissection, 2 cadavers underwent simulation of the MUS procedure by a urogynecologist. Samples were paraffin embedded and serially sectioned. Immunohistochemistry was performed using markers of prostate tissue and innervation.

OUTCOMES

Redundant immunohistochemical localization of markers for prostatic tissue and innervation of the glandular tissue of the AVW-FPT, including the region of MUS implantation.

RESULTS

Female periurethral glands were immunoreactive for markers of male prostatic tissue, including prostate-specific antigen, androgen receptor, HOXB13, and NKX3.1. Markers of innervation (protein gene product 9.5, choline acetyl transferase, and vasoactive intestinal polypeptide) also localized to certain regions of the glandular tissue and associated blood supply. Surgical simulation of the MUS procedure demonstrated that some periurethral glands are located in close proximity to an implanted sling.

CLINICAL TRANSLATION

The AVW-FPT contains glandular tissue in the surgical field of MUS implantation. Iatrogenic damage to the female periurethral glands and the associated innervation during surgery could explain the negative impacts on sexual dysfunction reported following MUS procedures.

STRENGTHS AND LIMITATIONS

This is the first study to characterize the female periurethral glands using markers of prostatic tissue in concert with markers of general and autonomic innervation and characterize their anatomical relationships within the surgical field of MUS implantation. The small sample size is a limitation of this study.

CONCLUSION

We provide further evidence that the AVW-FPT contains innervated glands that are phenotypically similar to the male prostate and may share a common embryonic origin. The microscopic and immunohistochemical features of the periurethral glands may be indicative of their functional capacity in sexual responses. The location of these glands in the surgical field of MUS procedures underscores the clinical significance of this tissue.

Should We Call It a Prostate? A Review of the Female Periurethral Glandular Tissue Morphology, Histochemistry, Nomenclature, and Role in Iatrogenic Sexual Dysfunction

INTRODUCTION

There is evidence of glandular tissue within the region of the anterior vaginal wall-female periurethral tissue (AVW-FPT) having similar morphology and immunohistochemistry to the prostate in men and having physiological roles in the female sexual response (FSR). Whether this tissue should be called a prostate in women has been debated. Iatrogenic injury to structures of the AVW-FPT, including these glands and the associated neurovasculature, could be a cause of female sexual dysfunction (FSD).

OBJECTIVES

To consolidate the current knowledge concerning the glandular tissue surrounding the urethra in women, evidence was reviewed to address whether: (i) these glands comprise the prostate in women, (ii) they have specific functions in the FSR, and (iii) injury to the AVW-FPT and prostate has sexual dysfunction as a likely outcome.

METHODS

A literature review was conducted using keywords including female prostate, Skene's/paraurethral glands, periurethral tissue, Gräfenberg (G)-spot, female ejaculation, mid-urethral sling (MUS), and sexual dysfunction.

RESULTS

Histological and immunohistochemical studies of the glandular tissue surrounding the urethra support the existence of prostate in women. Evidence suggests this tissue may have physiologically and clinically relevant autonomic and sensory innervation, and during sexual arousal may contribute to secretions involved in ejaculation and orgasm. Gaps in knowledge relating to the functional anatomy, physiological roles, and embryological origins of this tissue have impeded the acceptance of a prostate in women. Injury to the innervation, vasculature, and/or glandular tissue within the surgical field of MUS implantation suggests iatrogenic sexual dysfunction is plausible.

CONCLUSIONS

Continuing to advance our understanding of the morphology, histochemistry, and physiologic capacity of this glandular tissue will clarify the characterization of this tissue as the "prostate" involved in the FSR, and its role in FSD following surgical injury.

Short-term results of stress urinary incontinence in women undergoing laparoscopic sacrocolpopexy with and without midurethral sling

OBJECTIVES

This study aimed to assess the short-term results of stress urinary incontinence (SUI) in women undergoing laparoscopic sacrocolpopexy (LSC) with and without midurethral sling (MUS).

METHODS

This retrospective study was conducted from July 2012 to December 2017. Women with stage 3 or 4 in the Pelvic Organ Prolapse Quantification (POP-Q) who underwent LSC were recruited. Multichannel urodynamic studies were performed in all women. Assessment included pre- and postoperative POP-Q stages, urodynamic parameters, peri- and postoperative complications, and symptoms.

RESULTS

One hundred and eighteen patients met the inclusion criteria in total. A total of 19.5% (23/118) of them had concomitant MUS. The mean follow-up duration was 16.9 ±  16.0 (range 3-69) months. Meanwhile, 33.9% (40/118) of the patients were diagnosed with overt SUI, and 50% (20/40) underwent MUS. In the concomitant MUS group, the rate of having postoperative SUI was only 5% (1/20). Patients diagnosed with SUI and without concomitant MUS had a 45% rate (9/20), and 25% of them (5/20) received MUS later. Preoperatively, 16.1% (19/118) of the patients were diagnosed with occult SUI. Among the patients without anti-incontinence sling during prolapse surgery, 25% (4/16) of them complained about having SUI during the follow-up. However, none of the women required subsequent anti-incontinence surgery. Postoperative de novo SUI occurred to 13.6% (16/118) of them. None of the patients received further operation. Based on the preoperative and postoperative urodynamic studies in the combination surgery group, a significant improvement was observed in the pad test.

CONCLUSIONS

The combination of LSC with MUS procedure is likely to be beneficial in selected patients.

Sexual Quality of Life After Treatment of Stress Urinary Incontinence With Adjustable Tension-free Mesh System in Women Who Were Sexually Active Before Surgery

OBJECTIVE

To assess the sexuality and quality of life of sexually active women with stress or mixed urinary incontinence (SUI or MUI) after surgery with adjustable tension-free suburethral mesh system (transobturator adjustable tape or transvaginal adjustable tape).

MATERIALS AND METHODS

This intervention study with 2 years of follow-up (visits at 3 months, 1 year, and 2 years) involved 60 women with SUI or MUI who underwent surgery using transobturator adjustable tape or transvaginal adjustable tape during 2008-2014 in a Spanish region. The variables of interest measured pre- and postintervention were the global scores on the following questionnaires: (1) the Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaire-12; (2) the International Consultation on Incontinence Questionnaire; and (3) the Incontinence Quality of Life Questionnaire. Mixed linear models were constructed to determine the effect of the intervention on the outcome variables.

RESULTS

A significant improvement (P <.001) was seen over time in all the questionnaires, although between the 1- and 2-year visits there was a slight deterioration in all of them.

CONCLUSION

The technique provided an improved quality of life and sexuality, which was maintained at all the postoperative visits compared with baseline.

A Meta-Analysis Detailing Overall Sexual Function and Orgasmic Function in Women Undergoing Midurethral Sling Surgery for Stress Incontinence

Introduction

More than 200,000 midurethral slings are placed yearly for stress urinary incontinence. Approximately 14% to 20% of women experience worsening sexual function overall after these procedures. We postulated that sling placement injures neural pathways regulating “female prostate” tissue within the anterior vaginal wall.

Aim

To perform a meta-analysis for overall sexual function and orgasm using validated questionnaires for transvaginal tape, transobturator tape, and their variants.

Methods

Effect sizes of preoperative and postoperative questionnaire scores for overall sexual function and orgasm were calculated. Random-effects models were selected for meta-analyses. Statistical analysis involved determination of the ratio of total heterogeneity to total variability.

Main Outcome Measures

Differences of overall sexual and orgasm functions were calculated by subtracting postoperative sling scores from preoperative sling scores. Forest plots of effect sizes were performed.

Results

Sixty-seven percent of midurethral sling procedures analyzed showed no change or improvement in overall sexual function postoperatively, whereas 33% of studies analyzed for orgasm function showed improvement after the procedure. For transvaginal tape, mean total sexual function and orgasm postoperative scores were significantly higher than preoperative scores. For transobturator tape, mean total postoperative score was significantly higher than the preoperative score; however, the mean orgasm postoperative score was not significantly higher than the preoperative score, possibly because of variability in transobturator tape data.

Conclusion

There is a discrepancy between postoperative sexual satisfaction and orgasmic function after midurethral sling surgery. Although overall sexual function remained the same or improved for most women, orgasmic function in only one third of cases improved overall, with most women experiencing no change or deterioration in orgasmic function. Dissection for, and placement of, the midurethral sling can compromise the neural integrity of the anterior vaginal wall, thereby detrimentally affecting the periurethral prostate tissue that is essential to the orgasmic response. We propose that this surgical procedure can compromise orgasmic function in some women.

Questionnaires in the assessment of sexual function in women with urinary incontinence and pelvic organ prolapse

CONTEXT

Integrating sexual health in clinical practice is important. In women with pelvic floor disorders, the evaluation of the anatomical defects, lower urinary tract function and the anorectal function often receives more attention than the sexual function.

METHODS

Review of Medline using defined search terms to identify articles related to sexual health assessment in urogynecology and manual analyses was performed. Only articles published in English or Spanish were included.

RESULTS

Only 50% of women attending urogynecological clinics are sexually active. Of those, 60% present with some sort of sexual sexual dysfunction (FSD). Questionnaires and sexuality scales would facilitate discussion of sexual matters between the Health Care professionals and the women, and may increase the likelihood of FSD being diagnosed. The Pelvic Organ Prolapse Incontinence Sexual Questionnaire (PISQ) and the PISQ-IR (IUGA-Revised) are the only female sexual function specific questionnaires currently validated and developed specifically to assess sexual function in women with urinary incontinence and/or pelvic organ prolapse. Furthermore, the PISQ-IR also allows evaluation of the outcomes of women who are not sexually active when requiring urogynecologic care. PISQ-IR is also designed for international validation. In order to use the PISQ-IR in Spain, a proper interpretation and validation of the questionnaire is needed.

CONCLUSIONS

The evaluation of sexual function through specific questionnaires facilitates the identification of the sexual dysfunctions associated to the pelvic floor disorders. The inclusion of sexuality questionnaires as an outcome measure allows to analyze the impact in the sexual life of women treated for an urogynecological problem.

Outcome and sexual function after transobturator tape procedure versus tension-free vaginal tape SECUR: a randomized controlled trial

OBJECTIVE

This study aims to compare efficacy, safety, and sexual function between inside-out transobturator tape (TVT-O) and tension-free vaginal tape SECUR (TVT-S) procedures for stress urinary incontinence (SUI) treatment.

METHODS

Ninety-four women without concomitant pelvic organ prolapse repairs were randomly allocated to undergo TVT-O or TVT-S procedure. Demographic data, intraoperative and postoperative complications, and surgical outcomes were analyzed. Patients completed the Chinese version of the Incontinence Impact Questionnaire Short Form and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire Short Form (PISQ-12) before surgical operation and on follow-up after surgical operation.

RESULTS

There were no significant differences in cure rates between the two groups at 12 and 24 months of follow-up. Hematomas occurred in two patients in the TVT-O group. Urinary retention and de novo urinary urgency were similar in both groups. Operative time was significantly shorter for patients in the TVT-S group (P < 0.05), and postoperative groin/thigh pain was higher (P < 0.05) in the TVT-O group. In both groups, Incontinence Impact Questionnaire Short Form scores improved significantly after surgical operation (P < 0.001). Compared with a mean (SD) score of 33.9 (4.5) postoperatively (12 mo), the total PISQ-12 score before surgical operation was 30.9 (6.5), representing a significant difference (P = 0.021) in the TVT-S group. There was no significant difference in PISQ-12 scores before and after the TVT-O procedure.

CONCLUSIONS

The two techniques seem to be equally effective for SUI treatment. However, TVT-O results in a higher rate of groin/thigh pain and longer operative time. TVT-S can improve quality of life and sexual function in women with SUI.

Beyond the G-spot: clitourethrovaginal complex anatomy in female orgasm

The search for the legendary, highly erogenous vaginal region, the Gräfenberg spot (G-spot), has produced important data, substantially improving understanding of the complex anatomy and physiology of sexual responses in women. Modern imaging techniques have enabled visualization of dynamic interactions of female genitals during self-sexual stimulation or coitus. Although no single structure consistent with a distinct G-spot has been identified, the vagina is not a passive organ but a highly dynamic structure with an active role in sexual arousal and intercourse. The anatomical relationships and dynamic interactions between the clitoris, urethra, and anterior vaginal wall have led to the concept of a clitourethrovaginal (CUV) complex, defining a variable, multifaceted morphofunctional area that, when properly stimulated during penetration, could induce orgasmic responses. Knowledge of the anatomy and physiology of the CUV complex might help to avoid damage to its neural, muscular, and vascular components during urological and gynaecological surgical procedures.

Changes in sexual function and comparison of questionnaires following surgery for pelvic organ prolapse

PURPOSE

The aim of this study was to evaluate the effect of surgical repair of pelvic organ prolapse on female sexual function and to assess correlations between the two using two current standardized questionnaires.

MATERIALS AND METHODS

From October 2009 to September 2010, 143 patients with posterior compartment or combined vaginal prolapse were included. We assessed surgical outcomes according to anatomical change in the vagina and results of the Female Sexual Function Index (FSFI) and Pelvic Organ Prolapse/Urinary Incontinence Sexual Function questionnaire (PISQ-12) both pre- and postoperatively.

RESULTS

Among the 143 preoperative patients, 99 and 84 patients responded to the PISQ-12 and FSFI, respectively. The mean PISQ-12 score increased after surgery (p<0.001). Specifically, postoperative scores for questions 8 and 12 were higher than their respective preoperative scores (p<0.001). Postoperatively, mean FSFI score changed only slightly (p=0.76), and only the score for the satisfaction domain was improved (p=0.023). In regards to vaginal anatomy, vaginal length was significantly greater postoperatively (6.99±0.18 vs. 7.56±1.08, p<0.001), and postoperative vaginal caliber was narrowed to a two-finger width.

CONCLUSION

In this study, surgery for pelvic organ prolapse was shown to affect female sexual function. Moreover, menopause was associated with a change in postoperative sexual function.

Short-term effect of TVT-SECUR procedure on quality of life and sexual function in women with stress urinary incontinence

STUDY OBJECTIVE

To investigate whether patient quality of life and sexual function are improved after the tension-free vaginal tape SECUR (TVT-S) procedure (H-type).

DESIGN

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

SETTING

Single-center hospital.

PATIENTS

Thirty-three women with stress urinary incontinence (SUI) (high urethral mobility) and no concomitant pelvic floor prolapse underwent TVT-S between October 2009 and October 2011.

INTERVENTION

TVT-S procedure.

MEASUREMENTS AND MAIN RESULTS

Before and after surgery(6 and 12 months), all patients completed the Chinese version of the Incontinence Quality of Life Questionnaire (I-QOL). In addition, 28 sexually active patients who underwent the TVT-S procedure completed the short-form Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) before and after surgery (6 and 12 months). We used a paired t test to compare I-QOL scores before and after surgery. The Wilcoxon signed-rank test was used to compare the preoperative and postoperative PISQ scores. The objective cure rate was 78% (26 of 33 patients) at 12 months after surgery. The objective improvement rate was 12.1% (4 of 33 patients). The subjective satisfaction rate was 90%. Three operations (9.1%) were considered failures. Two patients underwent a TVT procedure after TVT-S because of recurrence. No patients reported severe pain; the mean (SD) visual analog scale pain score was 1.8 (1.2) after surgery. Only 1 patient (3%) was found to have sling erosion at 12 months postoperatively. The I-QOL score was 28.3 (14.2) before surgery and increased to 69.5 (18.9) at 12 months after the TVT-S procedure. The I-QOL score improved significantly after surgery (p <.001). The total PISQ-12 score at 6 months after surgery in all sexually active patients was 33.82 (0.87), compared with 31.57 (1.20) before surgery (p <.05). Physical domain scores on the PISQ-12 demonstrated significant improvement, increasing from 12.61 (0.75) to 14.36 (0.49) (p <.05). No significant difference was found between I-QOL and PISQ-12 scores at 6 and 12 months after surgery. There was no significant difference in total PISQ-12 scores in premenopausal patients before and after surgery (p >.05).

CONCLUSIONS

Although the objective cure rate was not high, the TVT-S procedure is a minimally invasive, safe, and effective surgical procedure for treatment of SUI (high urethral mobility) and can improve the quality of life and sexual function in women with SUI.

Prospective follow-up of female sexual function after vaginal surgery for pelvic organ prolapse using transobturator mesh implants

INTRODUCTION

Although the use of transobturator mesh implants for pelvic organ prolapse repair has been shown to be safe and effective, concern exists that the presence of prosthetic material in the vagina may adversely affect sexual function.

AIM

To evaluate the impact of transobturator mesh implantation on sexual function using validated questionnaire.

MAIN OUTCOME MEASURES

Female Sexual Function Index (FSFI), a validated 19-item questionnaire that assesses six domains of sexual function (desire, arousal, lubrication, orgasm, satisfaction, and pain), was used. The questionnaire was administered preoperatively, and at 3, 6, 12, and 24 months postoperatively. Clinical data were also recorded at each time point.

METHODS

Prospective nonrandomized study including 96 women with pelvic organ prolapse (cystocele, rectocele, vault prolapse). Transvaginal anterior or posterior wall repair using transobturator mesh implants with or without concomitant transobturator sling procedure.

RESULTS

Mean age was 51.4 ± 5.2 years. Mean operating time was 47.6 ± 23.4 minutes, and the mean hospitalization period was 3.8 ± 1.6 days. After initial decrease during the first 3 months, patients experienced a steady improvement in their sexual function. At 24 months postoperatively, the total mean FSFI score reached significantly higher values compared to the baseline (P = 0.023). Furthermore, pain-free intercourse improved during the follow-up reaching mean score of 4.27 ± 0.79 (P < 0.05) after 2 years. Pelvic floor examination at 2 years follow-up showed excellent surgical results with only 3.1% of the patients presenting with stage II vaginal wall prolapse.

CONCLUSIONS

Surgical repair of symptomatic pelvic organ prolapse using mesh implants results in improvement of major parameters of sexual function. A worsening in pain with intercourse during the initial months postoperatively lessens after 3 months as healing is completed.
