The effects of mediolateral episiotomy on pelvic floor function after vaginal delivery.

OBJECTIVE: To evaluate the effect of mediolateral episiotomy on puerperal pelvic floor strength and dysfunction (urinary and anal incontinence, genital prolapse). METHODS: Five hundred nineteen primiparous women were enrolled 3 months after vaginal delivery. Puerperae were divided in 2 groups: group A (254 women) comprised the women who received mediolateral episiotomy and group B (265 women) the women with intact perineum and first- and second-degree spontaneous perineal lacerations. Each woman was questioned about urogynecological symptoms and examined by digital test, vaginal perineometry, and uroflowmetric stop test score. Data were subjected to Student t test and Fisher exact test to assess, respectively, the difference between the mean values and the proportions within the subpopulations. Using a simple logistic regression model to test an estimate of relative risk, we expressed the odds ratios of the variables considered with respect to the control population (group B). RESULTS: No significant difference was found with regard to the incidence of urinary and anal incontinence and genital prolapse, whereas dyspareunia and perineal pain were significantly higher in the episiotomy group (7.9% versus 3.4%, P = .026; 6.7% versus 2.3%, P = .014, respectively). Episiotomy was associated with significantly lower values, both in digital test (2.2 versus 2.6; P < .001) and in vaginal manometry (12.2 versus 13.8 cm water; P < .001), but not in uroflowmetric stop test. CONCLUSION: Mediolateral episiotomy does not protect against urinary and anal incontinence and genital prolapse and is associated with a lower pelvic floor muscle strength compared with spontaneous perineal lacerations and with more dyspareunia and perineal pain. LEVEL OF EVIDENCE: II-2

Perineal ultrasound evaluation of urethral angle and bladder neck mobility in women with stress urinary incontinence

Objectives 1. To assess the reproducibility of an electronic ultrasonographic technique for the measurement of urethral angulation; 2. To test the ability of measurement of the urethral angle and bladder neck mobility to predict genuine stress incontinence; 3. To compare ultrasound variables in stress incontinent women and in controls.

Postpartum urinary symptoms: prevalence and risk factors

OBJECTIVES To assess the prevalence of urinary symptoms, the relationship between urinary symptoms and vaginal descent, and the association between urinary symptoms and obstetric factors. STUDY DESIGN Five hundred and thirty-seven women were interviewed and underwent a urogynaecological evaluation 3 months after vaginal delivery. Quantitative-type variables were subjected to Students t test. Simple logistic regression analyses were carried out on the symptoms studied as a function of risk factors. RESULTS 8.2% of primiparae showed stress urinary incontinence and multiparae in 20% (P=0.0001); urge incontinence was present in 5.5% of primiparae and in 13% of multiparae (P=0.004). Significant correlations were found among operative vaginal delivery, dysuria (P=0.048) and frequency (P=0.036). Urinary incontinence appeared associated with induced labour with prostaglandins (P=0.018) and with general maternal factors, such as parity (P=0.001) and elevated weight at the beginning of pregnancy (P=0.019). CONCLUSIONS It is likely that the pathogenesis of postpartum urinary incontinence includes not only the effects of pelvic floor trauma on urethrovesical mobility under stress, but also a deficiency in urethral resistance caused by drugs, such as prostaglandins.

Prevalence of urinary incontinence in young and middle-aged women in an Italian urban area

OBJECTIVE To investigate by questionnaire the prevalence and characteristics of urinary incontinence (UI) in a female population aged between 18 and 49. STUDY DESIGN Of 44,095 females aged 18-49.9 living in our urban area a sample of 10,000 subjects was sent a questionnaire and 3557 replied. The age-based analysis was performed on 2900 of these. RESULTS The overall prevalence of UI was 20%. 11% had suffered from nocturnal enuresis before 18 years old, 47% of parous women noted a relationship between the beginning of UI and delivery. Among the incontinent women 83% lost urine with physical exertion, and 44% had urge incontinence, 18% used diapers, 20% had consulted a physician and half of these had been referred for medical, surgical or rehabilitative therapy, 50% reported past or present urinary infections, 8% complained also of faecal incontinence, 22% considered loss of urine embarrassing and humiliating but only 6% revealed frustration and 2% were obliged to stay at home for long periods of time. Of the incontinents 62% defined themselves anxious or nervous and 22% of these ascribed an increase of urinary leakage to anxiety or to nervousness, 9% reported use of antidepressant drugs, 85% had sexual intercourse and only 2% considered UI as an impediment to a satisfying sexual activity. CONCLUSIONS UI is a common problem in young women. Urge incontinence seems to be prevalent in <30 aged women while stress incontinence occurs more frequently after this age.

Immediate postpartum perineal examination as a predictor of puerperal pelvic floor dysfunction.

OBJECTIVE To determine the relation between postpartum perineal trauma and the development of puerperal pelvic floor dysfunctions. METHODS A prospective study was conducted on 218 primiparae immediately after vaginal delivery. Women were divided in three groups according to perineal trauma: group A (n = 171) intact perineum or superficial tear, group B (n = 39) perineal muscle tears, group C (n = 8) anal sphincter tears with or without disruption of the rectal mucosa. Two months later, each woman was questioned about urogynecologic symptoms and examined by digital test, vaginal perineometry, and uroflowmetric stop test score. RESULTS No significant difference was found among the groups with regard to the incidence of stress incontinence, frequency/urgency, and urge incontinence, whereas anal incontinence was found more commonly in group C (group C versus group A: P =.003, odds ratio 18.78). No significant difference was found for digital test, perineometry, and uroflowmetric stop test. CONCLUSION Immediate postpartum perineal examination is not a good predictor of stress incontinence and pelvic floor weakness but could identify women at risk for anal dysfunctions: intact perineum does not exclude the appearance of symptoms related to perineal trauma after vaginal delivery.

The urine stream interruption test and pelvic muscle function in the puerperium

Objectives: This study assesses the role of the uroflowmetric urine stream interruption test (UST) in the evaluation of postpartum pelvic floor muscle function. Method: Two months after vaginal delivery, 492 women who underwent a digital test, vaginal manometry, and a UST were divided into two groups: continent and incontinent. Variables were subjected to the Students t‐test and to Fishers exact test to verify the difference between the two groups. Results: Digital test and vaginal manometry results were higher in the continent group, but only the UST showed significantly different values (P=0.001). All test results of incontinent puerperae who underwent rehabilitation were significantly improved after treatment. Conclusions: UST is low cost, non‐invasive, and can give objective information about pelvic floor performance after a vaginal delivery. It can be used for both routine clinical use and an outcome measure for women who undergo rehabilitation treatment.

Effects of epidural analgesia during labor on pelvic floor function after vaginal delivery

Background. Aims of this study were to determine the rate of symptoms related to perineal trauma (anal and stress urinary incontinence) and to assess pelvic floor muscle function in women who underwent epidural analgesia.
