Introduction: In context of Nepal, pelvic organ prolapse prevalence is estimated at 10% among women of reproductive age and 24% among post menopausal women. This study was carried out to measure the aorta sacral promontory distance among the females referred for contrast enhanced CT abdomen in a tertiary hospital.

 

Methodology: This prospective study was performed in a tertiary hospital in Nepal. Data were collected over the period of 4 months from July to October 2019 with total of 140 patients who underwent Contrast Enhanced CT abdomen. The age, height and weight of the patients were noted. In this study, aorta sacral promontory distance was determined. 

 

Results: The mean age was 48.20 years, mean BMI was 23.91 and mean aorta sacral promontory (APT) distance was 4.57±0.90 cm. Increased in age was correlated with decrease in APT distance but there was no correlation between BMI and APT distance. According to this study, APT distance was decreased in elderly female patients but no significant change in BMI and APT. 

 

Conclusion: In this study using CT, we found that as the age increased, APT distance decreased and there was no significant change in relation to BMI. Therefore, during sacral colpopexy, the surgeon should be careful and consider the aorta sacral promontory distance in the elder female patients while performing dissection.
