Objective : To assess the efficacy of the TINTARA uterine manipulator and the Cohen cannula for gynecologic
laparoscopy.
Material and Method: Sixty women scheduled for laparoscopy were randomized for use of TINTARA (n = 30)
or Cohen (n = 30) as a uterine manipulator. The degree of anterior and lateral deviation of the uterus,
operative time, surgical complications and ease of use were recorded and compared between the two groups.
Results : The mean ranges of anterior and lateral deviation of the uterus in TINTARA and Cohen groups were
61.17 + 19.37 vs. 49.33 + 22.58 degrees (p = 0.033) and 107.03 + 39.68 vs. 85.5 + 37.52 degrees (p = 0.035)
respectively. The percentage of patients having dye leakage from the cervix in the Cohen group was greater
than in the TINTARA group, but the difference was not statistically significant. Both instruments provided
similar ease of use. Complications were not found in either group.
Conclusion : TINTARA was found to have more advantages than the Cohen in moving the uterus in both
anterior and lateral directions.
