Can the delivery method influence lower urinary tract symptoms triggered by the first pregnancy?

Association between pregnancy and nocturia: A National Health and Nutrition Examination Survey analysis

AIMS

This study aimed to determine the impact of pregnancy and pregnancy-associated characteristics on nocturia.

METHODS

Using the National Health and Nutrition Examination Survey (NHANES) database from 2005/06 to 2017/18, we analyzed women who completed the "Reproductive Health" and "Kidney Conditions-Urology" questionnaires by sorting them into three groups: nulligravida, previously pregnant (nonpregnant with prior pregnancies), and currently pregnant. After excluding patients with pre-existing conditions impacting nocturia or with incomplete data, we weighed and matched the groups for age, race, BMI, and number of pregnancies. The relationships of nocturia to pregnancy in all groups and pregnancy-associated characteristics (gestational diabetes mellitus [GDM], history of multiple pregnancies, and trimesters of pregnancy) in currently pregnant women were assessed.

RESULTS

Of 8330 women that indicated pregnancy status, 1544 women (age range: 20-44 years; 523 nulligravida, 498 previously pregnant, 523 currently pregnant women) were included in analysis. Currently, pregnant women had a higher prevalence of nocturia than previously pregnant and nulligravida women (56.4% vs. 22.5% vs. 16.1%, p < 0.001) and had the highest odds of nocturia (OR: 6.82, p < 0.001). GDM or history of multiple pregnancies showed no associations in currently pregnant women. Increasing trimesters were associated with nocturia, with the third trimester showing the highest odds (OR​​​: 10.35, p < 0.001) and a greater average of nighttime voids than the first and second trimesters (2.40 ± 1.42 vs. 1.56 ± 1.31 and 1.88 ± 1.32, p < 0.001).

CONCLUSIONS

The association noted between pregnancy and nocturia, which strengthened with increasing trimesters, demonstrates that nocturia can significantly impact quality of life and therefore must be addressed during pregnancy.

Risk Factors for Urinary Incontinence in Primiparous Adolescents after Vaginal Delivery: A Cohort Study

STUDY OBJECTIVE

To evaluate urinary incontinence (UI) risk factors in primiparous adolescents between 7 and 48 months after vaginal delivery.

DESIGN

Cohort study.

SETTING

Physical Therapy Laboratory on Women's Health and Pelvic Floor at the Federal University of Pernambuco.

PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES

Cohort follow-up time was 7-48 months after delivery, guaranteeing that no participant presented with UI until 7 months after the infant's birth. Primiparous adolescents aged 10-19 years were included in the study, and those who had UI during pregnancy were excluded. Sample size was estimated at 140 volunteers, considering the calculation for logistic regression, with 20 observation units for each of the 7 variables proposed in the theoretical model developed for the study. The volunteers answered the evaluation form, providing information on the outcome of interest and possible risk factors. Univariate logistic regression analysis was performed.

RESULTS

The following risk factors for UI were identified in primiparous adolescents after vaginal delivery: episiotomy (Relative risk [RR]_a, 2.75; 95% confidence interval [CI], 1.22-6.06), large newborn for gestational age (RR_a, 4.58; 95% CI, 1.68-12.46) and less than six prenatal appointments (RR_a, 2.51; 95% CI, 1.05-6.04).

CONCLUSION

Professionals working in maternal health care should pay special attention to primigravid mothers, guide prenatal appointments, avoid routine episiotomy, and use obstetric practices recommended by the World Health Organization.

Prevalence, potential risk factors, and symptomatic bother of lower urinary tract symptoms during and after pregnancy

OBJECTIVES

Nationwide prospective studies of lower urinary tract symptoms (LUTS) during and after pregnancy have never been conducted in mainland China. A prospective longitudinal study was performed to evaluate the association of pregnancy and delivery on LUTS in a representative sample of primiparous Chinese women.

METHODS

A national survey on urinary incontinence (UI) was conducted in 10,098 pregnant females during late pregnancy (37 to 42 weeks of gestation) and at 6 weeks postpartum.in seven administrative regions of China from September 2007 to May 2009. No intervention was implemented. International Consultation on Incontinence Questionnaire Female Lower Urinary tract Symptoms Module (ICIQ-FLUTS) was administered. The participants were asked about the presence of individual LUTS and rated their symptom bother. Data were analyzed by descriptive statistics, Chi-square tests, and multivariate logistic regression.

RESULTS

Among all participants (mean ± SD maternal age 26.44 ± 3.97 years), the most commonly reported storage LUTS during pregnancy were nocturia (72.3%) and frequency (43.9%). LUTS were much less prevalent after childbirth than during pregnancy. Moderate to severe bother was more common during than after pregnancy. Compared with vaginal delivery (VD), cesarean section (CS) was a protective factor against voiding LUTS (AOR (adjusted odd ration), 0.66; 95% CI, 0.52-0.82) and storage LUTS (AOR, 0.74; 95% CI, 0.66-0.83).

CONCLUSIONS

LUTS were much more prevalent during than after pregnancy, with nocturia and frequency being the most prevalent. Moderate or severe bother was more common during pregnancy than after pregnancy. CS was associated with a decreased prevalence both of storage and voiding LUTS after delivery.

Associated factors to urinary incontinence in women undergoing urodynamic testing

OBJECTIVE

Analyzing factors associated with urinary incontinence (UI) among women submitted to urodynamic testing.

METHOD

A cross-sectional study of 150 women attended at a urological center. Data were analyzed using univariate and multivariate statistics.

RESULTS

White women (79.3%), overweight (45.3%), menopausal (53.3%), who drink coffee (82.7%), sedentary (65.3%), who had vaginal birth (51.4%), with episiotomy (80%), and who underwent the Kristeller maneuver (69%). 60.7% had Urethral Hypermobility (UH). A statistical association was found between: weight change and UH (p = 0.024); menopause, Intrinsic Sphincter Deficiency (ISD) and Detrusor Instability (DI) (p = 0.001); gynecological surgery, ISD and DI (p = 0.014); hysterectomy and all types of UI (p = 0.040); physical activity and mixed UI (p = 0.014).

CONCLUSION

Interventions and guidance on preventing UI and strengthening pelvic muscles should be directed at women who present weight changes, who are sedentary menopausal women, and those who have undergone hysterectomy or other gynecological surgery. Studies on pelvic strengthening methods are needed in order to take into account the profile of the needs presented by women.

OBJETIVO

MÉTODO

Estudo transversal realizado com 150 mulheres atendidas em um centro urológico. Os dados foram analisados por meio de estatística uni e multivariada.

RESULTADOS

Mulheres brancas (79,3%), com sobrepeso (45,3%), na menopausa (53,3%), que ingeriam café (82,7%), sedentárias (65,3%), que fizeram parto normal (51,4%), com episiotomia (80%), que sofreram Manobra de Kristeller (69%). 60,7% apresentavam HipermobilidadeUretral (HU).Houve associação estatística entre: mudança de peso e HU (p=0,024); menopausa,Deficiência Esfincteriana Intrínseca (DEI) e Instabilidade Detrusora (ID) (p=0,001); cirurgia ginecológica, DEI e ID (p=0,014); histerectomia etodos os tipos de IU (p=0,040); realização de atividade física eIU mista (p=0,014).

CONCLUSÃO

Intervenções e orientações quanto à prevenção da IU e ao fortalecimento da musculatura pélvica devem ser voltadas amulheres que apresentam mudança de peso, sedentárias, que se encontram na menopausa e àquelas que realizaram histerectomia ou outra cirurgia ginecológica. São necessários estudos sobre métodos de fortalecimento pélvico, de modo a contemplar o perfil dasnecessidades apresentadaspelas mulheres.

Risk factors for postpartum urinary incontinence

OBJECTIVE

To investigate the risk factors for postpartum urinary incontinence (UI) and its characteristics.

METHOD

This was a case-control study with 344 puerperal women (77 cases and 267 controls) with up to 90 days postpartum. In a single session, participants were given a questionnaire with sociodemographic and clinical data and two others that assessed urine leakage, leakage situations, and type of UI.

RESULTS

Stress UI was present in 45.5% of the women, incidents of urine leakage several times a day in 44.2%, of which 71.4% were in small amounts and 57.1% when coughing or sneezing. In 70.1% of cases, UI began during pregnancy and remained through the postpartum period. After running a binary logistic regression model, the following factors remained in the final model: UI during pregnancy (OR 12.82, CI 95% 6.94 - 23.81, p<0.0001), multiparity (OR 2.26, CI 95% 1.22 - 4.19, p=0.009), gestational age at birth greater or equal to 37 weeks (OR 2.52, CI 95% 1.16 - 5.46, p=0.02) and constipation (OR 1.94, CI 95% 1.05 - 5.46, p=0.035).

CONCLUSION

Most often, UI first appeared during pregnancy and remained through the postpartum period. Urinary incontinence during pregnancy, multiparity, gestational age at birth greater or equal to 37 weeks, and constipation were presented as risk factors. In the studied group, stress UI was more frequent.

OBJETIVO

Investigar os fatores de risco para a incontinência urinária (IU) no puerpério e as suas características.

MÉTODO

Trata-se de estudo caso-controle com 344 puérperas (77 casos e 267 controles), com até 90 dias pós-parto. Foi aplicado, em um único momento, um questionário para os dados sociodemográficos e clínicos, e dois outros para avaliar a perda urinária, situações de perda e o tipo de IU.

RESULTADOS

Apresentaram IU de esforço 45,5%, perda urinária diversas vezes ao dia 44,2%, sendo 71,4% em pequena quantidade e 57,1% ao tossir ou espirrar. Em 70,1% dos casos a IU iniciou-se na gestação e permaneceu no puerpério. Ao ajustar-se um modelo de regressão logística binária, apenas IU na gestação (OR 12,82, IC 95% 6,94 - 23,81, p<0,0001), multiparidade (OR 2,26, IC 95% 1,22 - 4,19, p=0,009), idade gestacional no parto maior ou igual a 37 semanas (OR 2,52, IC 95% 1,16 - 5,46, p=0,02) e constipação (OR 1,94, IC 95% 1,05 - 5,46, p=0,035) permaneceram no modelo final.

CONCLUSÃO

A IU iniciou-se frequentemente na gestação e permaneceu no puerpério. A presença de IU na gestação, multiparidade, idade gestacional no parto maior ou igual a 37 semanas e constipação foram fatores de risco. No grupo estudado a IU de esforço foi a mais frequente.

Reduced Pelvic Floor Muscle Tone Predisposes to Persistence of Lower Urinary Tract Symptoms after Puerperium

Pregnant primiparous women at term were enrolled in the study. ICIQ-FLUTS questionnaire was used to find out prevalence of LUTS. MOS was used to assess pelvic floor muscle strength. Women were followed up after 8-10 weeks of delivery to find out remission or persistence of these symptoms. We found that increased frequency of micturition was the most common (82%) LUTS seen in primiparous women at term. More than half (51%) of these women who complained of LUTS had a poor pelvic floor muscle tone (MOS grade 3). Out of those who had symptoms during pregnancy 11% remained symptomatic even after puerperium. Interestingly 61% of those with persistence of symptoms demonstrated a very poor pelvic floor muscle tone at term (MOS grade 2), while the remaining 39% also had a tone of only MOS grade 3. Thus women with LUTS during pregnancy should be screened for their pelvic floor muscle tone with simple MOS system which will help to predict the persistence of these symptoms later on. Women with a low score (three or less) should be triaged for regular pelvic floor muscle exercises.
