In this review, we aimed to assess the diagnostic performance of ultrasound for assessing the tumor spread in the abdomen in women with ovarian cancer. A search for studies evaluating the role of ultrasound for assessing intrabdominal tumor spread in women with ovarian cancer compared to surgery from January 2011 to March 2023 was performed in PubMed/MEDLINE, Web of Science, and Scopus databases. The Quality Assessment of Diagnostic Accuracy Studies 2 evaluated the quality of the studies (QUADAS-2).

- The study compared MRI and transvaginal ultrasound (TVS) in detecting myometrial invasion (MI) in low-grade endometrioid endometrial carcinoma.
- Four articles were included in the meta-analysis, which indicated that MRI had a pooled sensitivity of 65% and specificity of 85%, while TVS had a sensitivity of 71% and specificity of 76%.
- The results showed no significant difference between the two imaging techniques, highlighting that both are similarly effective, but more research is needed due to the limited number of studies available.
Objective: Bladder endometriosis is the presence of stroma and endometrial glands in the thickness of the detrusor muscle. The main symptoms it produces are dysuria and hematuria whose intensity is directly proportional to the size of the nodule. It is a difficult entity to diagnose for which physical examination is essential.

It has many advantages compared to other more invasive (lower complication rate) or non-invasive techniques (accurate diagnosis). Furthermore, it offers greater availability, it does not radiate, enables the study of pelvic masses accessible vaginally with ultrasound control in real time, and it is possible to use the colour Doppler avoiding puncturing large vessels among others.

Methods: We used a general electric Voluson E10 (General electric, Wauwatosa, WI, USA) to perform transvaginal ultrasonography. These images were shared after thorough counselling, and obtaining informed consent from the patient.
