Although several previous studies have reported changes in the vaginal axis in women who have undergone SCP, laparoscopic lateral mesh suspension, sacrospinous ligament fixation surgery for prolapse, there is a lack of data on changes in the vaginal axis after pectopexy. The aim of this study was to evaluate the degree of anatomical correction achieved by laparoscopic pectopexy in patients with apical genital prolapse using magnetic resonance imaging (MRI). Methods Individuals who experienced pectopexy and a nulliparous control group were enrolled in this prospective observational case-control investigation. MRI scans were conducted on both the control cohort and the study group before and after the procedure. The angles formed by the pubococcygeal line and the inferior vaginal segment, the levator plate and the pubococcygeal line, as well as t...

METHODS We retrospectively analyzed out patient database and evaluated 27 patients who had percutaneous nephrolithotripsy. From the DICOM data of patient's preoperative CT images, stone structures were obtained using an image identification system. All DICOM files were saved in the stereolithography file format and a 3D printed model was created. True stone volume was found by water displacement method using this model and this volume compared with ellipsoid formula and 3D-reconstructed volume. RESULTS Stone volume on water displacement ranged from 0.38-29.8cm3 with a median of 17.5cm3, stone volume on ellipsoid formula ranged from 0.46-34.7cm3 with a median of 19.6cm3 and stone volume on CT based 3D-reconstructed ranged from 0.48-31.8cm3 with a median of 18.9cm3.

Seventy-six patients with clinical signs of peripheral arterial occlusive disease were included in the study. MRA was performed using a fast contrast-enhanced high-resolution 3D technique that covered the area from the distal abdominal aorta to the distal lower limbs in two examination steps. In all patients, diagnostic images comparable with those of conventional intraarterial digital subtraction angiography (DSA) could be obtained. No false-negative findings were seen in the iliac, femoral, or popliteal arteries. Ten to 16% of the mild stenoses and 6-14% of the severe stenoses, mainly in the crural vessels, were overgraded compared with intraarterial DSA. Particularly in patients with proximal severe obstructions or occlusions, the crural segments could be depicted more clearly due to decreased arterial runoff in conventional angiography. The consistency of the excellent depiction of the vascular territories of the distal aorta and the pelvic and lower limb arteries in a standardized setting suggests great potential for the use of MRA in the primary diagnosis of peripheral arterial occlusive disease.

Therefore, to make this diagnosis, it should be considered in the differential diagnosis of musculoskeletal system pain. With this perspective, the aim was to present a 17-year-old patient who was diagnosed on magnetic resonance imaging with bone marrow edema and to highlight characteristics of this rare condition in the pediatric and adolescent population.
