Review
Endometriosis is a complex disease, which is defined by abnormal growth of endometrial tissue outside the uterus. It affects about 10% of women of reproductive age all over the world. Endometriosis causes symptoms that notably worsen patient's well-being-such as severe pelvic pain, dysfunction of the organs of pelvic cavity, infertility and secondary mental issues. The diagnosis of endometriosis is quite often delayed because of nonspecific manifestations. Since the disease was defined, several different pathogenetic pathways have been considered, including retrograde menstruation, benign metastasis, immune dysregulation, coelomic metaplasia, hormonal disbalance, involvement of stem cells and alterations in epigenetic regulation, but the true pathogenesis of endometriosis remains poorly understood. The knowledge of the exact mechanism of the origin and progression of this disease is significant for the appropriate treatment. Therefore, this review reports the main pathogenetic theories of endometriosis based on current studies.

Laparoscopy, with its many advantages, has revolutionized the field of pelvic surgery and enabled surgeons to gain a far greater understanding of pelvic anatomy. As technology evolves, our understanding is continuously improving. This article is a tribute to the anatomy of the pelvis, which itself has resisted evolutionary changes and remained the same, whereas our understanding of how to view and approach various organ structures has evolved.

Anatomical nomenclature commonly does not follow changes in the clinical language and demands. Therefore we tried to explain the pelvic relationships based on the changes that occur in the pelvis as well as to compare different nomenclatural strategies used in every day language. Courses of fasciae in the male and female pelvis are also considered.

Review
Abdominal wall and spinal soft tissue findings are frequently encountered on CT or MR imaging of the abdomen and pelvis. Many of these entities have specific imaging findings, for which a definitive diagnosis can be made without the need for further work up. These abdominal wall and spinal findings may be diagnostically challenging for sub-specialized abdominal radiologists who are unfamiliar with their appearance and appropriate management. This review article describes and illustrates pathognomonic or characteristic abdominal wall and spinal pathologies, which reside outside the abdominopelvic cavity. The cases selected all have findings that allow a confident diagnosis without further imaging or intervention. The cases presented include myonecrosis, intramuscular abscess, myositis, iliopsoas bursitis, Morel-Lavallée lesion, hydrocele of canal of Nuck, Klippel Trenaunay Weber syndrome, neurofibroma with target sign, perineural cysts, filum terminale lipoma, calvarial bone flap, transverse rectus abdominis muscle (TRAM) flap, liposuction, and hidradenitis suppurativa, among others. Although not all-encompassing, this paper will help abdominal radiologists to accurately diagnose a variety of abdominal and pelvic extra-cavitary soft tissue pathologies by identifying key radiologic findings.

Review
Nonobstructive azoospermia (NOA) can be caused by various diseases, including congenital disorders, endocrine disorders, infections, tumor or tumor-like diseases, vascular diseases, etc. Diagnosis of the underlying cause of NOA is complicated and challenging. In this study, we introduce an MR examination protocol for the etiological diagnosis of NOA, and demonstrate a series of NOA patients with different causes and imaging findings. Except for lesions of testes, the patients may also combine abnormalities of adrenal glands and central nervous system. In such cases, the patients could benefit from additional abdominal and intracranial scans.

Review
The anatomies of pelvic structures are critical for the diagnosis of pelvic floor dysfunctions. However, because of the complex background, the imaging appearances of pelvic organs and muscles are frequently distorted by noise and partial volume effect. Magnetic resonance imaging with its clear imaging quality of the female pelvic cavity is preferred for many studies. As such, correct segmentations of the pelvic structures on MR images are required for accurate diagnoses. Effective algorithms for axial T2-weighted MR images have been proposed, which are based on the imaging features of different structures and various image clues. In this paper, we review these algorithms and evaluate their performance, and discuss implementation issues and aspects towards constructing the three-dimensional models.

A case of actinomycosis involving the pelvic cavity is reported. The patient had a pelvic mass clinically and radiographically. Barium enema examination showed a mass with extrinsic compression and fixed narrowing of the rectum with mucosal irregularity. A computed tomographic scan showed a pelvic mass displacing the rectum.

Review
Understanding anatomy is one of the pillars for performing a safe, effective, and efficient surgery, but recently, it is reported that there has been a decline in teaching anatomy during the preclinical years of medical school. There is also evidence that by the time a medical student becomes a clinician, a considerable proportion of the basic anatomy knowledge is lost. Hence, it is crucial for surgeons performing or assisting in pelvic floor surgery to revisit this integral clinical aspect of pelvic anatomy for performing a safe surgery. Pelvic organ prolapse repair, especially abdominal laparoscopic sacrocolpopexy, which is the gold standard of pelvic organ prolapse repair, presents a significant challenge to surgeons because the technique requires thorough and meticulous negotiation through abdomino-pelvic vascular structures and nerves supplying the pelvis, rectum, and ureters. The abdominal laparoscopic sacrocolpopexy surgery requires surgeons to have a deep understanding of anatomy to prevent potential life-threatening complications, which is as critical as it is for a pilot to understand the navigation route for a safe landing. This review is an extensive look and a great reminder to laparoscopic surgeons working in the pelvic cavity, especially those performing a pelvic floor surgery, about the anatomical safe routes for performing laparoscopic pelvic floor repairs. For easy reading and clear understanding, we have described step by step the safe anatomical journey a surgeon needs to take during laparoscopic sacrocolpopexy. We divided the technique into five critical anatomic locations (landmarks), which serves as our "flight map" for performing safe and efficient laparoscopic sacrocolpopexy.

Severe pelvic traumatisms are associated with elevated mortality because of the high risk of exsanguination from multiple sources of bleeding. Treatment should encompass resuscitation, bone stabilization and hemorrhage control by arterio-embolization or surgery. Pre-peritoneal packing has been described in hemodynamically unstable patients who need damage control. The surgical technique of this simple and effective procedure is fully described by the authors with some complementary useful technical advices.

This study was carried out to determine the morphometric values of the pelvic cavity, the cranial and caudal pelvic aperture by three-dimensional (3D) reconstruction of the images obtained by computed tomography in adult Van Cats and to show the differences between these indicators in both genders. A total of 16 adult Van Cats, eight male and eight female, were used in the study. Animals were anesthetized with ketamine-xylazine combination and were scanned by computerized tomography. Images of the pelvic cavity were obtained. Three-dimensional reconstruction of the pelvis was performed with three-dimensional modelling program. Measurements of the diameters of the pelvic cavity, the cranial and caudal pelvic aperture were calculated from these images, and statistical analyzes were performed. Three-dimensional modelling of the pelvic cavity of Van Cats were examined between males and females. The results showed that there were significant (p < .05) differences between measurement of the pelvic inclination, the medial transverse diameter, the caudal transverse diameter and the angle between ischiatic arch. In addition, the correlations between age and weight were found statistically significant (p < .05) with the dorsal transverse diameter, the intermediate transverse diameter and the caudal transverse diameter in males. On the other hand, the correlations of age were statistically significant (p < .01) with the cranial pelvic aperture and the caudal pelvic aperture in females. In conclusion, some biometric values of pelvic cavity were observed to be statistically different in Van Cats.
