Impact of episiotomy on the urogenital hiatus using transperineal ultrasound.
AIMS To analyze whether episiotomy affects the urogenital hiatal area and the difference in the hiatus at rest and during contraction, as an indirect measurement of the contractile capacity of the levator ani muscle. METHODS We performed an observational, comparative, retrospective study of primiparous women who had normal vaginal deliveries. The urogenital hiatal area was compared in women w...
متن کاملAgreement between transperineal ultrasound measurements and digital examinations of cervical dilatation during labor.
BACKGROUND To compare 2D transperineal ultrasound assessment of cervical dilatation with vaginal examination and to investigate intra-observer variability of the ultrasound method. METHODS A prospective observational study was performed at Skane University Hospital, Lund, Sweden between October 2013 and June 2014. Women with one fetus in cephalic presentation at term had the cervical dilatati...
متن کاملImage-guided radiotherapy for prostate cancer using transperineal ultrasound
During a course of external beam radiotherapy the prostate gland moves both between radiotherapy fractions (interfractional motion) and during treatment (intrafractional motion). Some of this motion is related to changes in rectal and bladder filling, and movements are more marked in the antero-posterior direction as a result of rectal filling variability, compared to laterally and superoinferi...
متن کاملThe diagnostic accuracy of endovaginal and transperineal ultrasound for detecting anal sphincter defects: The PREDICT study.
AIM To determine the accuracy and predictive value of transperineal (TPU) and endovaginal ultrasound (EVU) in the detection of anal sphincter defects in women with obstetric anal sphincter injuries and/or postpartum symptoms of faecal incontinence. MATERIALS AND METHODS One hundred and sixty-five women were recruited, four women were excluded as they were seen years after their last delivery....
متن کاملUsing neural networks to predict road roughness
When a vehicle travels on a road, different parts of vehicle vibrate because of road roughness. This paper proposes a method to predict road roughness based on vertical acceleration using neural networks. To this end, first, the suspension system and road roughness are expressed mathematically. Then, the suspension system model will identified using neural networks. The results of this step sho...
