The impact of pregnancy and vaginal delivery on urinary incontinence

Urogynecological symptoms of the retroverted gravid uterus in the first half of the pregnancy: A retrospective cohort study of an underestimated, underdiagnosed and underreported issue

Background/Aim: Urogynecological symptoms, including pelvic pain, lower backache, feeling of bearing down, frequency, nocturia, urgency, stress incontinence, and urge incontinence, are common during pregnancy. But little has been reported regarding possible changes in lower urogenital tract anatomy and its effects in pregnancy. Therefore, the subject of this study is whether the incidence of urogynecological symptoms is higher when the uterus is retroverted in pregnancy. Methods: We enrolled 1432 pregnant women examined before the 20th week of pregnancy between January 2018 and March 2022. Patients were allocated into two groups according to whether the uterus was retroverted (n=226 (15.7%)) or anteverted (n=1206 (84.3%)). These two groups were compared regarding pelvic pain, lower backache, the feeling of bearing down, frequency, nocturia, urgency, stress incontinence, and urge incontinence. Results: Retroverted gravid uterus was noted in 11.8% (n=41) of nulliparae and 17% (n=185) of multiparae (P=0.021), with an overall prevalence of 15.7%. Of 1432 patients, the overall prevalence for frequency, urgency, nocturia, urge incontinence, stress incontinence, lower backache, pelvic pain, and feeling of bearing down were 31%, 26.7%, 18.2%, 5.4%, 7.5%, 6.9%, 56.4% and 7.5%, respectively. Between both groups, there were differences in frequency, urgency, nocturia and lower back pain. There were two patients with incarcerated gravid uterus with urinary retention. Conclusion: Patients with a retroverted uterus are more likely to experience the symptoms of lower back pain, frequency, nocturia, and urgency in the first half of pregnancy.

Prevalence, incidence and bothersomeness of urinary incontinence in pregnancy: a systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

Urinary incontinence (UI) is a common and embarrassing complaint for pregnant women. Reported prevalence and incidence figures show a large range, due to varying case definitions, recruited population and study methodology. Precise prevalence and incidence figures on (bothersome) UI are of relevance for health care providers, policy makers and researchers. Therefore, we conducted a systematic review and meta-analysis to investigate the prevalence and incidence of UI in pregnancy in the general population for relevant subgroups and assessed experienced bother.

METHODS

All observational studies published between January 1998 and October 2018 reporting on prevalence and/or incidence of UI during pregnancy were included. All women, regardless of weeks of gestation and type of UI presented in all settings, were of interest. A random-effects model was used. Subgroup analyses were conducted by parity, trimester and subtype of UI.

RESULTS

The mean (weighted) prevalence based on 44 included studies, containing a total of 88.305 women, was 41.0% (range of 9-75%). Stress urinary incontinence (63%) is the most prevalent type of UI; 26% of the women reported daily loss, whereas 40% reported loss on a monthly basis. Bother was experienced as mild to moderate.

CONCLUSIONS

UI is very prevalent and rising with the weeks of gestation in pregnancy. SUI is the most common type and in most cases it was a small amount. Bother for UI is heterogeneously assessed and experienced as mild to moderate by pregnant women.

Natural history of urinary incontinence from first childbirth to 30-months postpartum

PURPOSE

The objectives of this study were to determine the incidence of UI in a large cohort of primiparous women before and during pregnancy and over the course of 30-months postpartum, and to identify risk factors for UI during and after pregnancy.

METHODS

Nulliparous women aged 18-35 years with singleton pregnancies were interviewed in their third trimester and asked about urinary incontinence before and during pregnancy (n = 3001). After delivery these women were interviewed at 1, 6, 12, 18, 24 and 30-months postpartum and asked about urinary incontinence occurring in the month prior to each interview. Multivariable logistic regression models identified risk factors for UI during pregnancy and during the follow-up period.

RESULTS

Overall, 4% reported having urinary incontinence before pregnancy and 36.8% during pregnancy. The strongest predictor of urinary incontinence during pregnancy was urinary incontinence before pregnancy (adjusted OR 13.11, 95% CI 7.43-23.13). Among the women with no subsequent pregnancies, the rate of urinary incontinence increased from 12.5% at 6-months postpartum to 27.4% at 30-months postpartum, 52.1% reported UI at one or more postpartum data collection stages, and the strongest predictors of postpartum UI were UI before pregnancy (adjusted OR 3.95 (95% CI 1.60-9.75) and during pregnancy (adjusted OR 4.36, 95% CI 3.24-5.87).

CONCLUSION

Our findings suggest that primiparous women who report UI before and during pregnancy should be monitored for the continuation or worsening of UI over the course of the first 2-3 years postpartum, and treatment options discussed.

Prevalence, incidence and bothersomeness of urinary incontinence between 6 weeks and 1 year post-partum: a systematic review and meta-analysis

Introduction and hypothesis

Urinary incontinence (UI) is a common complaint for post-partum women. Reported prevalence and incidence figures show a large range due to varying study methodology. The crude prevalence of post-partum UI may differ when accounting for bother. Precise prevalence and incidence figures on (bothersome) UI are of relevance for health care providers, research planning, and policy makers. Therefore, we conducted a systematic review and meta-analysis to investigate the prevalence and incidence of UI in post-partum women in the Western world for relevant subgroups and assessed experienced bother in relation to UI.

Methods

Observational studies, published between January 1998 and March 2020 and reporting on prevalence and incidence between 6 weeks and 1 year post-partum, were included, regardless of type of UI or setting. We used a random effects model with subgroup analyses for post-partum period, parity and subtype of UI.

Results

The mean (weighted) prevalence based on 24 included studies, containing a total of 35.064 women, was 31.0%. After an initial drop in prevalence at 3 months post-partum, prevalence rises up to nearly the same level as in the third trimester of pregnancy at 1 year post-partum (32%). Stress UI (54%) is the most prevalent type. UI prevalence is equal among primi- and multiparous women. Experienced bother of UI is heterogeneously assessed and reported to be mild to moderate.

Conclusions

Post-partum UI is highly prevalent in women in the Western world. After an initial drop it rises again at 1 year post-partum. Experienced bother is mild to moderate.

Prolonged second stage effect on pelvic floor dysfunction: a follow up survey to a randomized controlled trial

BACKGROUND

Pelvic floor dysfunction is a group of disorders that can significantly impact quality of life due to persistent urinary and anal incontinence. Data evaluating the effect of prolonged second stage of labor and postpartum pelvic floor dysfunction is heterogenous and limited.

OBJECTIVE

To evaluate whether extending the length of labor in nulliparous women with prolonged second stage affects the presence of self-reported pelvic floor dysfunction after a randomized controlled trial of prolonged second stage.

STUDY DESIGN

We conducted a planned follow up survey to our randomized controlled trial of prolonged second stage of labor using the Pelvic Floor Distress Inventory-20 (PFDI-20). The primary outcome was the PFDI-20 summary score. Secondary outcomes included urinary and fecal incontinence, prolapse, and patient satisfaction. Women surveyed were nulliparous patients with epidural anesthesia, previously enrolled in a randomized controlled trial that assigned them to extended labor, at least 1 additional hour in the second stage if they were undelivered after three hours, or to usual labor, defined as expedited delivery after three hours in the second stage. Women were surveyed at 12 - 36 months postpartum.

RESULTS

Thirty-four of the seventy-eight women responded to the survey (43.6%). 17 women (50.0%) were from the extended labor group and 17 from the usual labor group (50.0%). Maternal demographic data were not significantly different between groups. The PFDI-20 summary score was 13.8 ± 23.3 in the extended labor group and 13.1 ± 20.9 in the usual labor group (p = 0.9). The Pelvic Organ Prolapse Distress Inventory-6 was 1.2 ± 2.9 in the extended labor group and 2.7 ± 6.4 in the usual labor group (p = 0.4). The Colorectal-Anal Distress Inventory-8 was 0.8 ± 2.8 in the extended labor group and 2.1 ± 4.0 in the usual labor group (p = 0.6). The Urinary Distress Inventory-6 was 11.8 ± 21.1 in the extended labor group and 8.3 ± 14.5 in the usual labor group (p = 0.6). Maternal and neonatal outcomes, as well as patient satisfaction, were not statistically significantly different between groups.

CONCLUSION

Extending the length of labor in nulliparas with singleton gestations, epidural anesthesia, and prolonged second stage did not have an impact on PFDI-20 scores at 12-36 months postpartum. However, our study was underpowered to detect small, but potentially clinically important, differences.

The impact of breastfeeding on pelvic floor recovery from pregnancy and labor

OBJECTIVE

Pelvic floor dysfunction (PFD) symptoms are prevalent during pregnancy and are mostly reversible thereafter. The pelvic floor muscles and their surrounding connective tissue support are estrogen-responsive. Breastfeeding is a condition of estrogen deficiency. We hypothesized that in breastfeeding women there may be a slower spontaneous recovery of PFD symptoms following birth. We aimed to determine the impact of breastfeeding on recovery from gestational PFD symptoms.

METHODS

We conducted a prospective cohort study of women who gave birth at the Soroka University Medical Center, Beer-Sheva, Israel. Those who have consented completed the Pelvic Floor Distress Inventory-20 (PFDI-20), after delivery and three months postpartum. Breastfeeding status was evaluated three months after delivery. Clinical and obstetrical characteristics were retrieved from the participants' medical records.

RESULTS

A total of 119 women had completed the PFDI-20 after delivery and three months postpartum. We found a significant difference between PFD during pregnancy, and PFD three months postpartum (P < 0.001). The overall PFDI-20 score was significantly decreased from a scale score of 64 to 27 (delta 36, P < 0.001), and this decrease remained significant for all components of the PFDI-20: pelvic organ prolapse distress (delta 14, P < 0.001); colorectal and anal dysfunction (delta 3.9, P = 0.01); and urinary dysfunction (delta 18, P < 0.001). No significant differences were noted in the extent of recovery of PFD symptoms between women who did and did not breastfeed (P = 0.59).

CONCLUSIONS

There is a clinical and statistically significant spontaneous recovery from gestational PFD symptoms at three months postpartum. Women with PFD symptoms prior to or during pregnancy can be reassured that breastfeeding probably does not delay the pelvic floor recovery.

Prevalence and risk factors for pelvic floor disorders during early and late pregnancy in a cohort of Austrian women

PURPOSE

To investigate the prevalence of pelvic floor disorders (PFDs) in a cohort of Austrian women either during their early or late pregnancy and to search for clinical risk factors which correlate with pelvic floor symptoms during pregnancy.

METHODS

A prospective study was conducted and 200 pregnant women answered the validated German pelvic floor questionnaire during their first or third trimenon of gestation. Furthermore, a multivariate logistic regression model was used to determine independent risk factors for PFDs after adjusting for confounders.

RESULTS

96/200 (48%) women reported psychological strain in at least 1 of the 4 pelvic floor domains while the remaining 104 women (52%) were asymptomatic. Affected women showed a significant higher BMI, a more frequent positive family history and a higher rate of multiple pregnancies was noted compared to asymptomatic women (p < 0.05). Furthermore, a statistically significant positive correlation could be observed between BMI, smoking and mean bladder score as well as mean prolapse score, signifying more symptom bother from bladder and prolapse in smokers with high BMI. A significant positive correlation was also detected between mean bowel score and parity. In the multivariate model, high BMI (CI 1.013-1.143), positive family history (CI 0.044-0.260) and multiple pregnancies (CI 0.011-0.244) remained independently associated with pelvic floor symptoms (p < 0.05).

CONCLUSION

Our results demonstrate that pelvic floor-related quality of life during pregnancy is a prevalent condition which is strongly affected by the expectant mother's weight as well as her family history. In addition, women with multiple pregnancies seem to be at increased risk.

Personal Preference of Mode of Delivery. What do Urogynaecologists choose? Preliminary Results of the DECISION Study

Introduction

Currently, almost every third child in Germany is delivered by caesarean section. Apart from straightforward and clear indications for caesarean section which account for approx. 10%, the large proportion of relative indications in particular needs to be critically reviewed if the current C-section rate is to be effectively lowered. It is more than doubtful, however, whether this can be a realistic goal in Germany, especially in the context of international developments. All studies on this topic demonstrate that the personal attitude of the obstetric team has a considerable influence on the pregnant womanʼs personally preferred mode of delivery. Therefore, in the first part of the DECISION study, the personal preferences of urogynaecologists were evaluated regarding the best suitable mode of delivery.

Material and Methods

All 432 delegates at the 9th German Urogynaecology Congress in Stuttgart in April 2017 were invited to participate in an online questionnaire study. The questionnaire was developed especially for this study.

Results

Of the 432 registered delegates, 189 (43.8%) participated in the survey. 84.7% (n = 160) of the study participants would prefer a vaginal delivery, in an otherwise uncomplicated pregnancy. Only 12.2% (n = 23) opted for an elective caesarean section. The main reasons stated for this decision were concerns about incontinence (87.5%) and pelvic floor trauma (79.2%). Amongst the study participants, 83.6% would like to be part of a risk stratification system presented in the questionnaire which, with the aid of specific parameters, is intended to allow early identification of a population with a high risk of developing pelvic floor disorders. There was also great interest in postpartum pelvic floor recovery (97.8%) and an associated optional pessary therapy (64.4%). The type of delivery already experienced (vaginal delivery vs. primary caesarean section) and parity also reveals to have a significant influence on the personal preferred mode of delivery as well.

Conclusions

Urogynaecologists prefer vaginal delivery for themselves. There is a great interest to participate in a risk stratification process in order to approach childbirth in an individualized and risk-adapted manner.

Gestational Urinary Incontinence in Nulliparous Pregnancy- A Pilot Study

INTRODUCTION

Urinary Incontinence (UI) in pregnancy is more than a disease; it is a social problem that necessitates special care and management. The exact rationales and biological facts behind urinary incontinence during pregnancy are unclear and multivariate.

AIM

This pilot study was designed to examine the direct effect of gestational factors (e.g., physical and metabolic/hormonal) on the presence of Gestational Urinary Incontinence (GUI), in nulliparous pregnant women.

MATERIALS AND METHODS

This was a questionnaire-based study comprising of 61 nulliparous pregnant woman who had not experienced any Urinary Incontinence (UI) before their pregnancies. Patients were examined during their pregnancies within the framework of the antenatal care program continued at the Division of Perinatology, Hacettepe University, Ankara, Turkey, between January 2015 and December 2016. A 'urinary incontinence questionnaire' was used three times during different periods of gestation (11-14, ~24 and ~37 gestational weeks) for each patient. Statistical analysis was performed using the SPSS software version 20.0. The Chi-Square test or Fisher's-exact test was used to compare proportions in groups.

RESULTS

The prevalence of total urinary incontinence (stress urinary incontinence, urge urinary incontinence and mixed urinary incontinence) in nulliparous pregnant women was 4.9% (n=3), 9.8% (n=6) and 26.2% (n=16) at 11-14, ~24 and ~37 gestational weeks, respectively. Stress urinary incontinence was found to be 3.3% (n=2), 6.6% (n=4) and 16.4% (n=10) at 11-14, ~24 and ~37 gestational weeks, respectively. Urge urinary incontinence frequency was found to be 1.6% (n=1), 3.3% (n=2), 6.6% (n=4), and mixed urinary incontinence frequency was 0% (n=0), 0% (n=0), 3.3% (n=2) at 11-14, ~24 and ~37 gestational weeks, respectively. Maternal age, birth weight of the neonate and gestational age at birth had no statistically significant effect on GUI.

CONCLUSION

Urinary incontinence is an important issue during pregnancy and related symptoms are more common in third trimester.

A Sanitary Pad for Self-Assessment of Rupture of Membranes

BACKGROUND

Multistep immunoassay kits for the diagnosis of rupture of membranes are relatively complex and are not designed to be used by pregnant women themselves. These kits require procedural steps of specimen extraction and preparation. We evaluated the ability of a sanitary pad containing a qualitative immunoassay for alpha-fetoprotein (AFP) to serve as a one-step self-test to detect amniotic fluid leakage.

TECHNIQUE

Four sets of pads were evaluated. The pads in the study set were worn by 288 pregnant women with confirmed rupture of membranes. Three controls were evaluated: 1) pads worn by 93 pregnant women with intact membranes, 2) additional pads instilled with urine specimens obtained from the 381 women described previously (study set plus control set 1), and 3) pads instilled with semen collected from 40 men.

EXPERIENCE

All 288 pads that absorbed amniotic fluid had positive results. Approximately half of the pads absorbed with normal vaginal discharge had a sufficient amount to yield valid results, which were all negative. All 381 pads with instilled urine and all 40 pads with instilled semen had negative results.

CONCLUSION

An immunoassay for AFP, embedded in a pad, appears to be a feasible and reproducible self-test for the detection of rupture of membranes.

Prevalence and trends of pelvic floor disorders in late pregnancy and after delivery in a cohort of Israeli women using the PFDI-20

OBJECTIVE

To investigate the prevalence of pelvic floor disorders (PFD) in a cohort of Israeli women at late pregnancy and three months postpartum, to define changes in PFD rates and to evaluate various obstetrical factors that may correlate with these changes.

METHODS

A prospective longitudinal cohort study was conducted between March and July 2014. The PFDI-20 questionnaire (validated in the Hebrew language) was used to evaluate pelvic floor distress symptoms 24h and 3 months after delivery (representing the third trimester and post-partum period, respectively). Patients with a preterm delivery (<36 completed weeks of gestation), delivery of a stillbirth, non-fluency in Hebrew and patients with inability to complete the questionnaire due to a communication problem were excluded from the study. In addition to the PFDI results demographic and clinical data were collected from the patients' medical records. Routine statistical methods were used to interpret the results.

RESULTS

During the study period 117 women answered the first questionnaire and only 37 had filled the second questionnaire. The most prevalent item group reported in the third trimester was the urinary distress symptoms. Urinary frequency was the most common with 65% of patients reporting this symptom. At the post-partum period the most prevalent item group reported was the colorectal and anal distress with 31.5% of patients reporting increased straining efforts. There was a mixed trend in the changes noted between the two questionnaires. While some items improved in the puerperium as compared with late pregnancy others have worsened. In a multivariable analysis the only statistically significant finding was that at the post-partum follow-up, stress urinary incontinence was significantly associated with spontaneous perineal tears at delivery. Other obstetrical parameters including episiotomy and birth weight were not found to be significantly associated with any of the PFD items.

CONCLUSION

We have demonstrated that PFD is prevalent both in late pregnancy and in the puerperium. There are mixed trends of spontaneous recovery following childbirth. A significant association between perineal tears and SUI 3 months after delivery was noted.

Lower Urinary Tract Symptoms and Urinary Incontinence During Pregnancy

OBJECTIVE

Lower urinary tract symptoms (LUTS) can frequently be seen in pregnant women. Pregnancy and delivery have been considered as risk factors in the occurrence of pelvic floor dysfunction and determinants of LUTS. The main associated risk factor is parity. In the present study, we aim to determine the frequency of LUTS and urinary incontinence (UI) during pregnancy and the associated risk factors.

METHODS

This prospective study was carried out in a total of 250 women during their 28- and 40-gestational week checks. The Urinary Distress Inventory-6, the Incontinence Impact Questionnaire-7, and International Consultation on Incontinence Questionnaire-Short Form were used to determine LUTS and its effect on quality of life.

RESULTS

The mean age and gestational age of the participants were 29.41 ± 5.70 year (range 18-44) and 35.45 ± 2.98 weeks (range 28-40), respectively. The prevalence of LUTS was 81.6%. The prevalence of UI during pregnancy was 37.2%. Stress urinary incontinence, urge urinary incontinence and mixed urinary incontinence were diagnosed as 15.6, 4.8 and 16.8%, respectively. We found that advanced age, smoking and multiparity were risk factors associated with incontinence. Incontinence reduced pregnant women's quality of life.

CONCLUSIONS

Lower urinary tract symptoms are commonly seen among pregnant women and these symptoms negatively affect the quality of life of pregnant women. Advanced age, smoking and multiparity were risk factors associated with urinary incontinence and LUTS. Obstetricians should be on the lookout for individual urological problems in pregnancy. Resolving any urological issues and cessation of smoking for the affected individuals will help alleviate the problem.

False vs True rupture of membranes

New medical nomenclature: False rupture of membranes or False ROM and Double rupture of membranes or Double ROM are being introduced into the English language. A single caregiver found about 1% of term births and 10% of term PROM involved False ROM, in which the chorion breaks while the amnion remains intact. Diagnostically, if meconium or vernix is observed, then both the chorionic and amniotic sacs have broken. In the absence of detection of vernix or meconium, an immediate accurate diagnostic test for False ROM is lacking and differentiating between True ROM from False ROM is possible only after leaking stops, which takes hours to days. The obvious benefit of differentiating between 'True' and 'False' ROM, is that in the case of False ROM, the amnion is intact and ascending infections are likely not at increased risk, although research is lacking as to whether False ROM is associated with an increased rate of ascending infection. Three cases of False ROM are presented and avenues for future research are enumerated.

Between suffering and hope: rehabilitation from urinary incontinence as an intervening component

This is a qualitative study seeking to understand Brazilian women's experience of urinary incontinence (UI) and design a representative theoretical model for the experience. Theoretical saturation occurred after analysis of the 18th non-directive interview in accordance with Grounded Theory. Two phenomena emerged: living with the challenges of UI and experiencing the hope and disappointment of rehabilitation from UI. Upon re-alignment of the components, the core category emerged, namely: between suffering and hope - rehabilitation from urinary incontinence as an intervening component. From the analysis in light of symbolic interactionism, pregnancy and vaginal birth were observed to be symbols of women's vulnerability to the suffering from living with the moral and physio-psychosocial challenges of UI. It is also inferred that the lack of consideration of the Unified Health System (SUS) in investing in the process of rehabilitation from UI may be having a negative effect on the incentive programs for promoting vaginal birth. Most of all, it reveals the ongoing suffering of women with UI, most of whom do not have access to rehabilitation due to the lack of programs geared to the real needs of these users of the Unified Health System.

Stress urinary incontinence in pregnant women: a review of prevalence, pathophysiology, and treatment

INTRODUCTION AND HYPOTHESIS

Stress urinary incontinence (SUI) is the most common type of urinary incontinence (UI) in pregnant women and is known to have detrimental effects on the quality of life in approximately 54.3 %. Pregnancy is the main risk factor for the development of SUI. This review provides details of the pathophysiology leading to SUI in pregnant women and SUI prevalence and treatment during pregnancy.

METHODS

We conducted a PubMed search for English-language and human-study articles registered from January 1990 to September 2012. This search was performed for articles dealing with prevalence and treatment of SUI during pregnancy. In the intervention studies, we included studies that used a randomized controlled trial (RCT) design or studies comparing a treatment intervention to no treatment.

RESULTS

A total of 534 articles were identified; 174 full-text articles were reviewed, and 28 of them met eligibility criteria and are reported on here. The mean prevalence of SUI during pregnancy was 41 % (18.6-60 %) and increased with gestational age. The increasing pressure of the growing uterus and fetal weight on pelvic-floor muscles (PFM) throughout pregnancy, together with pregnancy-related hormonal changes, may lead to reduced PFM strength as well as their supportive and sphincteric function. These cause mobility of the bladder neck and urethra, leading to urethral sphincter incompetence. Pelvic floor muscle exercise (PFME) is a safe and effective treatment for SUI during pregnancy, without significant adverse effects.

CONCLUSIONS

Understanding these issues can be useful for health-care professionals when informing and counseling pregnant women to help prevent SUI during pregnancy and the postpartum period.

Are transversus abdominis/oblique internal and pelvic floor muscles coactivated during pregnancy and postpartum?

AIM

The aim of this study was to simultaneously evaluate both transversus abdominis/internal oblique (Tra/IO) and pelvic floor muscles (PFM) during isometric exercises in nulliparous, pregnant, and postpartum women.

METHODS

The study included 81 women divided into four groups: (G1) nulliparous women without urinary symptoms (n = 20); (G2) primigravid pregnant women with gestational age ≥24 weeks (n = 25); (G3) primiparous postpartum women after vaginal delivery with right mediolateral episiotomy (n = 19); (G4) primiparous postpartum women after cesarean section delivery, with 40 to 60 days of postpartum (n = 17). The assessment consisted of simultaneous surface electromyography (EMGs) of the PFM and Tra/IO, during three isometric maximum voluntary contractions.

RESULTS

Only nulliparous women presented significant simultaneous Tra/IO and PFM co-activation when asked to contract PFM (P = 0.0007) or Tra/IO (P = 0.00001).

CONCLUSIONS

There is co-activation of the transversus abdominis/internal oblique and the pelvic floor muscles in young, asymptomatic nulliparous women. This pattern was modified in primigravid pregnant and primiparous postpartum women regardless of the delivery mode.

Vaginal delivery following single incision sling (TVT-Secur) for female stress urinary incontinence

In recent years, surgical treatment of stress urinary incontinence has become minimally invasive owing to the introduction of the transobturator route first and then single incision devices for positioning of mid-urethral slings. Although a number of case reports in the literature describe pregnancies successfully terminated both by vaginal delivery and cesarean section following mid-urethral sling positioning, there is still no definitive consensus on which is the preferred mode of delivery in these patients. We report a case of spontaneous vaginal delivery at term in a 41-year-old multiparous woman two years after the positioning of a single incision sling (TVT-Secur). The patient remained continent throughout the gestation and in the following 24 months. This case seems to further support the concept that sling procedures for stress urinary incontinence do not represent an absolute contraindication to spontaneous vaginal delivery, although the preferred mode of delivery must be assessed on an individual basis.
