    Incidentally discovered extrauterine migration of a Lippes loop: should we let it stay?
    (2024) Yaşar, Ayşenur Buz; Dağistan, Emine; Aktepe, Oktay Halit
    Intrauterine devices (IUDs), a form of long-acting reversible fertility control, are often preferred for preventing pregnancy. The Lippes loops, made of plastic, are inserted into the uterus via the cervix, fitting into the uterine cavity. The non- medicated (inert) structure of the loop allows for long-term IUD use. Uterine perforation and translocation of the IUD are the most threatening complications. In this case report, we present an asymptomatic 79-year-old woman with a forgotten IUD that migrated into the abdominal cavity and was discovered during her follow-up for lung cancer

    Volumetric segmentation analysis of the levator ani muscle using magnetic resonance imaging in pelvic floor function assessment
    (Turkish Soc Radiology, 2024) Yaşar, Ayşenur Buz; Yüzok, Rüveyde Begüm; Dağıstan, Emine
    PURPOSE In this case-control study, we aimed to evaluate how muscle volume affects pelvic floor function by analyzing the levator ani muscle (LAM) using volumetric segmentation in addition to standard magnetic resonance (MR) defecography assessments. METHODS We enrolled 85 patients with varying degrees of pelvic floor dysfunction (PFD) and 85 age- and gender-matched controls in this retrospective study. All patients had MR defecography images, while all controls had pelvic MR images obtained for other reasons. Group comparisons were performed using independent samples t-tests and Mann-Whitney U tests. The receiver operating curve (ROC) was constructed to establish a cut-off value for a normal LAM volume. Interrater reliability was assessed by calculating the intraclass correlation coefficient. A P value of less than 0.05 was considered statistically significant. RESULTS Volumetric measurements revealed that the control group had higher LAM volumes, and the ROC curve analysis indicated a cut-off value of 38934.3 mm 3 with a sensitivity of 0.812 and specificity of 0.8 for PFD assessment using LAM volumetric measurement. Gender did not significantly affect LAM volume in the control group. CONCLUSION Alongside the useful structural and functional information acquired from MR defecography images, volumetric analysis, and three-dimensional reconstructions of LAM may help to improve the accuracy of the diagnosis.
