  • relationship between the length of the Perineum and position of the anus and vaginal delivery in primigravidae
    International Urogynecology Journal, 2000
    Co-Authors: Diaa E E Rizk, Letha Thomas
    Abstract:

    The aim of the study was to determine perineal length and anal position in primigravidae and to evaluate their effect on vaginal delivery. The distances between the fourchette and each of the center of the anal orifice and the inferior margin of the coccyx were measured in 212 primigravidae with singleton term pregnancies during the first stage of labor. Anal position index was calculated by dividing the first measurement by the second. The mean ± SD length of Perineum was 4.6 ± 0.9 cm. The mean ± SD anal position index was 0.49 ± 0.12. Women with a short Perineum (<4 cm) or a small anal position index (<0.42) had significantly higher rates of episiotomy, perineal tears and instrumented delivery. This association was also significant by multiple logistic regression analysis. It was concluded that a short Perineum and anterior displacement of the anus were associated with traumatic vaginal delivery in primigravidae.

  • ultrasound assessment of fetal head Perineum distance before induction of labor
    Ultrasound in Obstetrics & Gynecology, 2008
    Co-Authors: T M Eggebo, C Heien, Inger Okland, Leif Gjessing, Pal Romundstad, Kjell A Salvesen
    Abstract:

    Objectives To evaluate fetal head–Perineum distance measured by ultrasound imaging as a predictive factor for induction of labor, and to compare this distance with maternal factors, the Bishop score and ultrasound measurements of cervical length, cervical angle and occiput position. Methods The study included 275 women admitted for induction of labor. The fetal head–Perineum distance was measured by transperineal ultrasound imaging as the shortest distance from the outer bony limit of the fetal skull to the skin surface of the Perineum. Cervical length and angle was measured by transvaginal ultrasound examination, and fetal head position was assessed by transabdominal ultrasound imaging. The Bishop score was assessed without knowledge of ultrasound measurements. Receiver–operating characteristics (ROC) curves were used for evaluation of the probability of a successful vaginal delivery. The time from induction to delivery was tested using Cox regression analysis with ultrasound measurements, parity and body mass index (BMI) as possible predictive factors. Results Areas under the ROC curve for prediction of vaginal delivery were 62% (95% CI, 52–71%) for fetal head–Perineum distance (P = 0.03), 61% (95% CI, 51–71%) for cervical length (P = 0.03), 63% (95% CI, 52–74%) for cervical angle (P = 0.02), 61% (95% CI, 52–70%) for Bishop score (P = 0.03) and 60% (95% CI, 51–69%) for BMI (P = 0.05). The Cesarean delivery rate was 22% among nulliparous and 5% among parous women (P < 0.01). Parity, fetal head–Perineum distance, cervical length and cervical angle were contributing factors predicting vaginal delivery within 24 h in a Cox regression model. Occiput posterior position had no significant predictive value. Conclusions Fetal head–Perineum distance measured by transperineal ultrasound examination can predict vaginal delivery after induction of labor, with a predictive value similar to that of ultrasonographically measured cervical length and the Bishop score. However, we judge none of these methods used alone to be good enough in a clinical setting. Copyright  2008 ISUOG. Published by John Wiley & Sons, Ltd.

  • median raphe cysts of the Perineum in children
    Urology, 2008
    Co-Authors: Lucas Krauel, X Tarrado, L Garciaaparicio, Javier Lerena, Mariona Sunol, Joan Rodo, J M Ribo
    Abstract:

    Median raphe cysts of the Perineum are uncommon congenital lesions of the male genitalia. They can be found all the way from the distal penis and scrotum toward the Perineum in a midline position. They are considered as congenital alterations in embryologic development. A case of a 6 year-old boy is presented. Review of the literature relevant to children was made regarding the embryologic, diagnostic, and treatment aspects. We believe it is important that adult and pediatric urologists recognize these lesions and their management to provide the appropriate information to the parents.
