However, it is difficult to manage cutting and suturing procedures within acceptable time periods. To overcome this difficulty, we applied a three-dimensional (3D) video system with laparoscopic partial nephrectomy, and evaluated its utility. Materials and Methods: We retrospectively enrolled 31 patients who underwent laparoscopic partial nephrectomy between November 2009 and June 2014. A conventional two-dimensional (2D) video system was used in 20 patients, and a 3D video system in 11. Patient characteristics and video system type (2D or 3D) were recorded, and correlations with perioperative outcomes were analyzed. Results: Mean age of the patients was 55.812.4, mean body mass index was 25.73.9 kg/m2, mean tumor size was 2.00.8 cm, mean R.E.N.A.L nephrometry score was 6.91.9, and clinical stage was T1a in all patients. There were no significant differences in operative time (p=0.348), pneumoperitoneum time (p=0.322), cutting time (p=0.493), estimated blood loss (p=0.335), and Clavien grade of >II complication rate (p=0.719) between the two groups. However, warm ischemic time was significantly shorter in the 3D group than the 2D group (16.1 min vs. 21.2min, p=0.021), which resulted from short suturing time (9.1 min vs. 15.2 min, p=0.008). No open conversion occurred in either group. Conclusions: A 3D video system allows the shortening of warm ischemic time in laparoscopic partial nephrectomy and thus may be useful in improving the procedure.
