Conservative Interventions for Urinary Incontinence on Postpartum Women: A Systematic Review and Meta-Analysis

INTRODUCTION

Urinary incontinence (UI) is common in postpartum women and can lead to a reduced quality of life and withdrawal from fitness and exercise activities. Conservative management interventions such as pelvic floor muscle training (PFMT), use of vaginal cones, and biofeedback have been recommended as first-line treatment. We aimed to explore the effects of conservative interventions on UI rate, severity, and incontinence-specific quality of life in postpartum women with UI.

METHODS

Nine databases were searched from inception to August 2022: PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, Wanfang, China National Knowledge Infrastructure, China Biological Medicine, and VIP Journal Integration Platform. Randomized controlled trials examining the effects of conservative interventions on postpartum UI were included.

RESULTS

Initial searches produced 1839 results, of which 17 studies were eligible. All included studies had a low to moderate risk of bias. Supervised PFMT and use of a vaginal cone were more effective than individual PFMT in decreasing rates of UI (odds ratio, 0.29; 95% CI, 0.14-0.61). Individual PFMT combined with acupuncture (mean difference, -1.91; 95% CI, -2.46 to -1.37) or electroacupuncture and supervised PFMT combined with moxibustion were more effective than individual supervised PFMT alone in improving the severity of symptoms. Furthermore, electrical stimulation and biofeedback combined with acupoint stimulation or core training were more effective than electrical stimulation and biofeedback alone. For improving the incontinence-specific quality of life, supervised PFMT was more efficacious than individual PFMT; electrical stimulation and biofeedback plus core training were more beneficial than electrical stimulation and biofeedback alone.

DISCUSSION

Supervised PFMT and use of a vaginal cone were more beneficial in decreasing rates of UI compared with individual PFMT. Superior effects in decreasing UI severity may be achieved by combining PFMT or electrical simulation and biofeedback with other therapies. Electrical stimulation and biofeedback plus core training, as well as supervised PFMT, are most effective in improving incontinence-specific quality of life. Further research is required to provide more evidence on the efficacy of these therapies.

Effect of Perineal Massage and Warm Compresses Technique in Postpartum Pelvic Floor Dysfunction. A Secondary Analysis from a Randomised Controlled Trial

Pelvic floor dysfunction (PFD) is common to be associated with pregnancy and birth. To date, no research has been done to understand whether the perineal massage and warm compresses technique has an impact on pelvic floor dysfunction. To assess the impact of perineal massage and warm compresses technique during the second stage of labor in pelvic floor dysfunction at 3 and 6 months postpartum. Of the 800 women recruited to randomised controlled trial to prevent perineal trauma, 496 were included in the study, with 242 (48.8%) assigned to the Perineal Massage and Warm Compresses (PeMWaC) group and 254 (51.2%) to the control group (hands-on). Used the Pelvic Floor Distress Inventory-20 (PFDI-20). The questionnaire is divided into three subscales: Urinary (UDI), Colorectal-Anal (CRADI), and Pelvic Organ Prolapse Distress Inventory (POPDI). The PeMWaC group had a significantly higher frequency of intact perineum (p < 0.001) and low-severity vaginal tears (tears without any other degree of perineal trauma) (p = 0.031) compared to the control group, while the control group had significantly more patients who suffered high-severity vaginal/perineal trauma (second degree perineal tears) (p = 0.031) and patients without spontaneous perineal trauma or vaginal tears who underwent episiotomy (p < 0.001). In addition, at 3 months postpartum, women in the control group had a higher Urinary Distress Inventory (UDI) score and global score, compared to the PeMWaC group, and after controlling for confounding variables, the perineal massage and warm compresses technique was associated with lower UDI scores at 3 months postpartum compared to control group. At 6 months postpartum, there were no differences in the UDI or global scores, indicating general recovery from perineal trauma. In addition to reducing perineal trauma during birth, the perineal massage and warm compresses technique was associated with a lower prevalence of early PFD symptoms, mainly urinary distress, at 3 months.Trial registration http://www.ClinicalTrials.gov NCT05854888, retrospectively registered.
