Fundal pressure in second stage of labor (Kristeller maneuver) is associated with increased risk of levator ani muscle avulsion.

OBJECTIVE: To investigate the association between application of fundal pressure during the second stage of labor (Kristeller maneuver) and the risk of levator ani muscle (LAM) injury. METHODS: This was a prospective case-control study of women recruited immediately after their first vaginal delivery in our university hospital between March 2014 and September 2016. Women who underwent the Kristeller maneuver were recruited as cases. For each case, a control (no Kristeller) was recruited matched for body mass index, use of epidural analgesia, duration of second stage of labor and birth weight. All women were invited to undergo four-dimensional (4D) transperineal ultrasound (TPU) 3-6 months postpartum. The main outcome measure was the presence of LAM avulsion on 4D-TPU. TPU results were compared between cases and controls. Multivariate logistic regression analysis was performed to identify independent risk factors for LAM avulsion. RESULTS: During the study period, 134 women in the Kristeller maneuver group and 128 women in the control group underwent TPU assessment. Women who underwent the Kristeller maneuver had a higher prevalence of LAM avulsion than did controls (38/134 (28.4%) vs 18/128 (14.1%); P = 0.005). In addition, women in the Kristeller-maneuver group had a larger hiatal area on maximum Valsalva maneuver and a greater increase in hiatal area from rest to maximum Valsalva. On multivariate logistic regression analysis, use of the Kristeller maneuver was the only independent factor associated with LAM avulsion (odds ratio, 2.5 (95% CI, 1.29-4.51)). CONCLUSION: The Kristeller maneuver is associated with an increased risk of LAM avulsion when applied in women during their first vaginal delivery. This should be taken into account when deciding to use fundal pressure to accelerate the second stage of labor and when counseling women following childbirth. Copyright © 2018 ISUOG.

Use of a preventive sling surgery for the simultaneous correction of latent stress urinary incontinence during the cystocele repair: two year follow-up.

AIM: The aim of this paper was to assess the feasibility and utility of adding a preventive trans obturatory tape (TOT) during the same intervention for anterior prolapse repair, in patients with masked urinary incontinence and massive cystocele. METHODS: A retrospective trial was conducted in a Tertiary care University Hospital. Ninety-nine women with a massive cystocele (Ba ≥2 cm of pelvic organ prolapse quantification) and an occult stress urinary incontinence were recruited from 2004 to 2010: 53 women were subjected to an anterior fascial reconstruction alone while 46 underwent the same intervention with the addition of TOT. Patients were also asked to rate their overall quality of life, using the International Consultation on Incontinence Modular Questionnaire-Lower Urinary Tract Symptoms Quality Of Life (ICIQ-LUTSqol). All patients were assessed at one, six, twelve and twenty-four months of follow-up. Statistical analysis was performed with SPSS 15.0 software; SPSS inc., Chicago IL, USA was performed using the Chi-square test with Fisher's post-hoc correction. RESULTS: At 24 month follow-up the rate of appearance of stress urinary incontinence at the urogynecological examination, was higher in the group without TOT (81% vs. 19%, P=0.004). In terms of overall quality of life, significantly higher rates of satisfaction have been reported by the group treated with additional TOT (P=0.006). CONCLUSION: The addition of TOT during the anterior prolapse correction seems to give a greater durability to the correction, resulting, in the long term, in a lower rate of urinary symptoms onset (first latency) and in a better quality of life compared to the traditional anterior colporrhaphy alone.
