About this trial

This study aims to provide a systematic anatomical and morphometric description of the female pelvic and lower abdominal retroperitoneum using cadaveric dissection, with direct application to gynecologic surgery.

Standardized dissections will be performed in adult female cadavers obtained from a body donation program. Key anatomical structures, including the ureter, iliac vessels, aorta, inferior vena cava, hypogastric plexuses, and lymphatic territories, will be identified and measured. Spatial relationships, distances, and anatomical variations will be recorded using direct measurements and standardized photographic documentation.

The study will quantify anatomical variability and asymmetry between right and left hemipelves, focusing on ureteral, vascular, and neural structures. The results are expected to improve surgical planning, particularly in nerve-sparing techniques and pelvic and para-aortic lymphadenectomy, and to support the development of an applied anatomical atlas for educational and clinical use.

Trial outcomes

Primary outcomes

Global Morphometric Characterization of the Female Pelvic and Lower Abdominal Retroperitoneum

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.

Time frame

Baseline

Secondary outcomes

Iliac Artery Morphometry and Branching Patterns

Measurement (mm) of ureteral distances relative to major vascular structures, length of the ureteral tunnel, and classification of anatomical variants including duplication and abnormal course.

Time frame

Baseline

Iliac Artery Morphometry and Branching Patterns

Measurement (mm) of diameter and length of common, external, and internal iliac arteries, and characterization of branching patterns including uterine, obturator, pudendal, vesical, rectal, and gluteal branches.

Time frame

Baseline

Iliac Venous Anatomy and Variations

Measurement (mm) of iliac venous diameters and lengths, description of venous relationships with arterial structures, and identification of relevant variants including deep circumflex iliac vein and uterine venous plexus.

Time frame

Baseline

Presence and Morphometric Characteristics of Corona Mortis

Corona mortis diameter (mm) and length (mm).

Time frame

Baseline

Other outcomes

Development of an Applied Anatomical Atlas

Integration of morphometric measurements and standardized photographic documentation to develop a clinically oriented anatomical atlas of the female pelvic and lower abdominal retroperitoneum for educational and surgical applications.

Time frame

through study completion, an average of 1 year
