Approximately 20 cadavers are expected to be included, depending on availability. Each hemipelvis will be considered an independent unit of analysis for side-to-side comparison.\n\nStandardized anatomical dissections will be performed following a predefined protocol. The retroperitoneum will be systematically exposed to identify and analyze key structures, including the ureter, iliac vessels and their branches, abdominal aorta, inferior vena cava, hypogastric plexuses, pelvic splanchnic nerves, and lymphatic territories.\n\nMorphometric measurements will be obtained using millimetric instruments and predefined anatomical reference points to ensure reproducibility. Variables will include distances between anatomical structures, vessel diameters, nerve relationships, and spatial organization of pelvic surgical spaces. All measurements will be performed at least twice, and standardized photographic documentation will be obtained.\n\nPrimary outcomes include quantitative morphometric parameters and spatial relationships between key anatomical structures, as well as the frequency of anatomical variations. Secondary outcomes include characterization of ureteral variants, iliac branching patterns, presence and morphology of corona mortis, organization of the pelvic autonomic nervous system, and assessment of right-left anatomical asymmetry.\n\nStatistical analysis will be descriptive, including measures of central tendency and dispersion for continuous variables, and frequency distributions for categorical variables. Comparative analyses between hemipelves will be performed using paired statistical tests.\n\nThis study does not involve living human participants, clinical interventions, or identifiable personal data. All procedures will be conducted in accordance with institutional and ethical standards for the use of donated human bodies for research and education.\n\nThe expected outcome is the development of a clinically oriented anatomical dataset and an illustrated anatomical atlas to support surgical training, improve understanding of pelvic anatomy, and optimize surgical approaches in gynecologic oncology.","Adult female cadavers obtained from an institutional body donation program, used for anatomical dissection and morphometric analysis of the pelvic and upper abdominal retroperitoneum.",[54],{"label":55,"type":49,"description":56,"interventionNames":57},"Cadaveric Specimens","Adult female cadavers obtained from an institutional body donation program.
