Comparison of Anatomical Structures in Trigonum Anale-Trigonum Urogenitale in Postpartum and Nulliparous Patients

There are many studies in the literature on pelvic anatomy and morphometry using MRI. Pelvic anatomy and the interrelationship of the structures here are extremely important for conditions such as urinary incontinence, pelvic organ prolapse, pelvic floor weakness and dictocia. In this study, the organs in the anal and genital trigone regions on the outer side of the pelvic floor were examined. Because the morphometry of the pelvis and the relationship and morphometry of the external genital, urinary and anal organs in the pelvic floor are as important as the inside of the pelvis. In the study, two groups of patients were determined: patients who had never given birth and patients who had given birth at least once. In the distance measurements of the organs in the pelvic floor, the tuber ischiadicum, a bony structure, was defined as a guide point. In measurement results, the distance between the right tuber ischiadicum and the lower border of the vagina is highly significant when comparing patients who have given birth and those who have not given birth (p=0.035). In addition, the distance between the left side tuber ischiadicum and the lower border of the vagina was found to be highly significant in both patient groups (p = 0.019).
