The pelvis and the spine form a system balancing human skeleton. Within this system, the pelvis adapts to age-related changes in the spine. Previous studies were predominantly focused on changes of pelvic parameters in the sagittal plane. The aim of this study was to reveal age-related changes of lesser pelvic dimensions at different levels of the pelvic cavity in the sagittal and coronal planes and to explore sexual dimorphism in age-related tendencies. The computed tomography pelvimetry was performed on the three-dimensional workstation. The research sample included 211 females aged 18 to 84 years and 181 males aged 18 to 82 years, who underwent an examination at the Riga East University Hospital, Clinical Center “Gailezers,” Latvia. Three pelvic angles and transverse and sagittal diameters of the lesser pelvis were measured at four levels: the inlet, two axial planes in the mid-cavity, and the outlet. The results demonstrated that more pronounced age-related changes occurred in the inlet and the outlet of the lesser pelvis. The mid-cavity was less changing. The transverse diameter between acetabular centers and the sagittal diameter at the level of ischial spines were independent of age. In general, the common age-related trends were observed for pelvic parameters in females and males. A single exception was the proportion of diameters at the level of ischial spines, which decreased in males only. For parameters associated with pelvic floor diseases, age-related changes occurred in the direction of pathology.

The fixation methods that can be used for unstable posterior pelvic ring injuries have undergone many innovative changes due to the recent development of surgical and imaging techniques. After understanding the appropriate indications of first and second sacroiliac screw fixation and spinopelvic fixation, innovative methods, including the trans-sacral screw fixation, posterior tension-band plate fixation, and the S2AI screw, would be chosen and applied. Considering the anatomical complexity and proximity to the surrounding vessels and nerves in the posterior fixation, the safe zone according to the fixation options should be well understood in preoperative planning. Moreover, the functional reduction of the posterior pelvic ring through the reduction and fixation of the anterior lesion should be achieved before placing the implant to reduce the number of malposition-related complications.

Objectives: This is a descriptive study to determine the origin of abnormal obturator arteries, the drainage of abnormal obturator veins, and if any anastomoses exist between these abnormal vessels in Filipino cadavers. Methods: A total of 54 cadaver halves, 50 dissected by UP medical students and 4 by UP Dentistry students were included in this survey. Results: Results showed the abnormal obturator arteries arising from the inferior epigastric arteries in 7 halves (12.96%) and the abnormal communicating veins draining into the inferior epigastric or external iliac veins in 16 (29.62%). There were also arterial anastomoses in 5 (9.25%) with the inferior epigastric artery, and venous anastomoses in 16 (29.62%) with the inferior epigastric or external iliac veins. Bilateral abnormalities were noted in a total 6 cadavers, 3 with both arterial and venous, and the remaining 3 with only venous anastomoses. Conclusion It is important to be aware of the presence of these abnormalities that if found during surgery, must first be ligated to avoid intraoperative bleeding complications.

This is a case of a 51-year-old, Filipino, multipara, presenting with a five-month history of gradually enlarging pelvoabdominal mass. Initially assessed with multiple myoma, a total abdominal hysterectomy with bilateral salpingooophorectomy and excision of pelvic mass were done. Histopathology report of the mass showed Rosai-Dorfman Disease (RDD) and immunohistochemical stains, CD68 and S100, were both confirmatory. RDD within the pelvic cavity is an extremely rare occurrence with only seven reported cases globally on a wide-literature search. This paper describes the clinical presentation, imaging, management and histopathology of the case. The objective is to increase awareness on the pelvic manifestation of RDD and to provide health care professionals with additional knowledge for diagnosis and management of similar cases.

FIGO stage III endometrial carcinoma, which is extending outside the uterus, but limited to the true pelvis represent a small subgroup of patients with endometrial carcinoma. This stage of disease is uncommon and only limited experience is available regarding the management of this advanced stage of disease. And isolated vaginal recurrence of endometrial carcinoma occurs infrequently following hysterectomy and appropriate use of external beam irradiation and brachytherapy. We experienced one case of recurrent endometrial carcinoma at the vagina after total abdominal hysterectomy with bilateral salpingo-oophorectomy and adjuvant radiotherapy for stage III endometrial cancer in 41-year old woman who was treated with complete local excision of vaginal recurrent cancer mass and locovaginal radiotherapy. The clinicopathologic finding and a review of literature on endometrial carcinoma were described briefly.

Endometriosis is a rare cause of an ureteral obstruction. We report a case of intrinsic ureteral endometriosis resulting in severe hydroureteronephrosis. The diagnosis of ureteral endometriosis may be considered in women with flank pain and ureteric obstruction within true pelvis.

Congenital arteriovenous malformations in the true pelvis are extremely rare : only 8 cases have been described in male patient. In most cases, the diagnosis may be obscure and the management is difficult due to frequent recurrence, so appropriate angiographic study is decisive in establishing the diagnosis and directing the mode of treatment. We report on 53 year old male patient who was treated with embolization due to congenital pelvic arteriovenous malformation with painless gross hematuria after erection or sexual intercourse. Diagnosis was established as periprostatic pelvic arteriovenous malformation by means of transrectal color Doppler ultrasonography and confirmed by angiography. Our attempt at management by embolization is described. A literature review and discussion of congenital arteriovenous malformation and worth of color Doppler ultrasonography are presented.

Pelvic nonunion is very difficult to treat. According to the nonunion site, anterior or posterior surgical approach should be used selectively. And if the nonunion site is located in both anterior and posterior, both anterior and posterior surgical approach should be used. We report a case of testicular necrosis after ilioinguinal approach used as a anterior approach to pelvis to treat pelvic nonunion developed as a result of unstable pelvic ring injury.

Researching anatomy of renal pelvis for removal renal intrasinal calculi. From 1/1998 to 6/1999, 44 kidneys of adult were researched by classical dissection, plastic cast, selective arteriogram and 45 cases of renal intrasinusal calculi were removed: 30 lower partial nephrectomy, 3 upper partial nephrectomy, 12 pyelonephrectomy (resnick or extended Gil - Vernet) with the result: non nephrectomy, non mortality. The placement of pelvis and advantage, disadvantage of each operative technique in this procedure has been shown.
