简要总结
This observational descriptive cadaveric study aims to describe the main anatomical relationships of the female pelvic retroperitoneum using standardized anatomical dissection. Adult female cadavers obtained from an institutional body donation program will undergo pelvic retroperitoneal dissection. Ten predefined anatomical relationships involving the ureter, pelvic vessels and nerves will be evaluated using a standardized anatomical checklist. Anatomical variability will be described for each item. Standardized photographs will also be obtained to develop an anatomical atlas for educational purposes.
详细描述
This is an observational, descriptive cadaveric study designed to characterize the main anatomical relationships of the female pelvic retroperitoneum with direct application to gynecologic surgery.
The study will be conducted using adult female cadavers obtained from an institutional body donation program. Approximately 20 cadavers will be included, depending on availability, providing a total of 40 hemipelves. Each hemipelvis will be considered an independent unit of analysis.
Standardized anatomical dissections of the pelvic retroperitoneum will be performed following a predefined protocol. The main anatomical structures relevant to gynecologic surgery will be identified, including the pelvic ureter, iliac vessels and their branches, obturator nerve, and other predefined anatomical landmarks.
Each hemipelvis will be evaluated using a standardized 10-item anatomical checklist. For every item, the reference anatomical pattern will be classified as present ("Yes"), absent ("No"), or not evaluable ("Not evaluable"). Anatomical variability will be calculated as the proportion of anatomical variants among all evaluable hemipelves for each item.
Standardized photographic documentation will be obtained throughout the dissections. Anatomical variants will be qualitatively described and illustrated whenever possible.

研究组 & 干预措施
Cadaveric Specimens
Adult female cadavers obtained from an institutional body donation program. Specimens will undergo standardized pelvic retroperitoneal dissection, completion of a predefined 10-item anatomical checklist, and photographic documentation.
干预措施: Anatomical Dissection (Other)
结局指标
主要结局
Global Morphometric Characterization of the Female Pelvic and Lower Abdominal Retroperitoneum
时间窗: Baseline
Systematic morphometric measurement (millimeters, mm) of anatomical structures in the female pelvic and lower abdominal retroperitoneum, including distances, diameters, lengths, and spatial relationships between ureter, vascular structures (iliac vessels, aorta, inferior vena cava), and pelvic autonomic nerves. Measurements will be obtained using standardized cadaveric dissection and predefined anatomical reference points.
Frequency of anatomical variation
时间窗: Baseline
Percentage of anatomical variation for each of the ten predefined anatomical relationships evaluated using a standardized anatomical checklist.
