All women with genital prolapse before surgical treatment are shown additional examination to detect latent urinary incontinence. The generally accepted tactic allows you to do this examination using the invasive method of CUDI (complex urodynamic examination), a trial test with a pessary (it takes about 7 days to wear a pessary for a long time). Ultrasound of the pelvic floor with 3D reconstruction and functional tests has a significant advantage, because it is a dynamic non-invasive method of examination, which significantly accelerates and clarifies the method of surgical treatment of the patient.

Ectopic pancreas is a congenital anomaly. Contrast-enhanced ultrasound through the gastric window after oral administration of gastrointestinal contrast agent, reveals the clear anatomical structures and morphological characteristics of the lesions in all layers of the gastric wall.

Female pelvic floor anatomy, which developed since the early 20th century, has had a variety of theories, including integral theory, three levels of vaginal support theory, "hammock hypothesis", and three-chamber system. Supporting structures such as pelvic floor muscles, fascia and ligament play an important role in maintaining the normal function of pelvic floor, among which levator ani muscle group is one of the most important supporting structures.

Primary pancreatic lymphoma is a very rare non-epithelial malignant tumor of the pancreas, representing only 0.5% of all pancreatic masses and only 2% of all extranodal lymphomas. The clinical manifestations and laboratory tests are non-specific, and the imaging manifestations are easily confused with other pancreatic malignancies such as pancreatic ductal adenocarcinoma, increasing the difficulty for diagnosis.
