The fundal pressure manoeuvre (FPM) is a procedure where the fundus of the uterus is pushed through the abdominal wall by the midwifes and doctors to shorten the terminal phase of the second stage vaginal delivery. Nowadays its use is controversial and associated with many adverse effects. The aim of the study was to evaluate benefits and adverse maternal outcomes after FPM. The correlation of the FPM with episiotomy was evaluated. The role of the FPM on pelvic floor dysfunction such as anal incontinence due to anal sphincter injury was assessed.The retrospective study was conducted between 2017 and 2021. The women who came to the postpartum examination to Gynaecology department for various reasons and gave vaginal birth to a singleton were included in the study. The women who had instrumental delivery were excluded. Minimal sample size was calculated with calculator.net and set on 45. Two groups were formed one with fundal pressure and one without, 96 and 90 patients respectively. The maternal, fetal, and obstetric factors that could be associated with the application of FPM were examined. The endoanal ultrasound examination was performed on all women included in the study.The study did not show that FPM would lead to a more frequent occurrence of anal sphincter injury (p = 0.73), effect its location (p = 0.77) and depth (p = 0.97), however the test group tended to have longer ruptures compared to control group (p = 0.1). No statistically significant differences in episiotomies between control and test group (p = 0.075) were shown. Endoanal ultrasound showed discrepancy between clinically stated and ultrasonographical diagnoses of anal sphincter injuries. In 61,3% of patients with anal sphincter injury after FPM, reported one of the anal incontinence problems of varying degrees six months after delivery.Given that the study proved that FPM is not correlated to the anal sphincter injury it can be used safely. The FPM should be performed carefully and only if necessary to safely finish the labour or in combination with instrumental delivery.
