Article Synopsis
  • Cystoscopy has long been the main method for detecting urothelial carcinoma (UCa), but its invasiveness and costs highlight the need for non-invasive detection methods, leading to the investigation of urinary biomarkers.
  • In a study involving 1,119 urine samples, researchers analyzed protein levels of biomarkers CXCL16 and TGFBI, along with DNA methylation at specific CpG sites, to assess their ability to identify UCa compared to other urological and gynecological cancers.
  • Results showed that while CXCL16 and TGFBI had moderate sensitivity (31% and 56%) and high specificity (94% and 85%), combining these proteins and methylation markers improved UCa detection sensitivity to 54%

Introduction: In order to guarantee the patient's right to self-determination, in the case of a relative indication for a secondary caesarean section the Supreme Court expects early information about this real treatment alternative and the patient's option to choose the delivery method. The aim of this study throughout Germany was to survey the status quo of legal compliance of the practice of providing information at all German obstetric clinics and a further comparison based on the clinic format.

Methods: All obstetric clinics in Germany were emailed within the context of an anonymous online study using a questionnaire developed on the basis of the BGH judgment of August 28, 2018 (AZ: VI ZR 509/17).

Introduction: The advantage of transcervical radiofrequency ablation (TRFA) is that it is minimally invasive, incision-free, and treats a wide spectrum of fibroids, including those that are not accessible by surgical hysteroscopy (FIGO 3, 4, 5, 6, and 2-5). However, there are no publications describing a combined procedure of operative hysteroscopy and TRFA yet, so it was still unknown whether a combined procedure is associated with additional risks.

Aim: To report the combined technique of transcervical intrauterine radiofrequency ablation of fibroids and surgical hysteroscopy.

Uterine fibroids are one of the most common diseases in female patients, lead mainly to bleeding disorders and lower abdominal pain, and reduce the chance of having children. In recent years we have seen a trend towards more and more pharmacotherapies and minimally invasive organ-preserving treatments. One novel and innovative procedure for an organ-preserving treatment of symptomatic uterine fibroids is the transcervical ultrasound-guided radiofrequency ablation (TRFA).

Electromechanical morcellation-so called power morcellation-is a minimally invasive approach to remove bulky lesions such as uterine fibroids. The spread of benign and malignant tissue due to morcellation is a major concern that might limit the use of laparoscopic interventions. We present an in vitro evaluation of the safety characteristics of a four-port endobag with closable trocar sleeves, and describe physical properties of the bag that may or may not allow passage through the hole.

Background: Transcervical fibroid ablation (TFA) is a minimally invasive, effective treatment of symptomatic uterine fibroids that utilizes intrauterine ultrasound for imaging and radiofrequency energy for ablation. Outcomes reported with TFA have been positive, with significant reductions in fibroid volume, improvements in symptom severity and health-related quality of life, and low complication and surgical reintervention rates. The SAGE registry characterizes the long-term (5-year) outcomes of TFA when used to treat symptomatic uterine fibroids in real-world usage.
