Objective: To examine perioperative, pathological and early continence outcomes of laparoscopic radical prostatectomy (RP) aided by a new-generation three-dimensional (3D) display system and compare them with those from the same operation aided by a conventional, two-dimensional (2D) display system. Patients and methods: A total of 95 consecutive patients underwent laparoscopic RP for clinically localized prostate cancer (PC) by an experienced single surgeon from October 2009 to December 2012. Baseline characteristics, perioperative and pathological variables and continence data at 3 months after surgery were retrospectively reviewed from a prospectively maintained database. Categorical and continuous variables were compared using χ2, Student's t and Wilcoxon rank-sum tests, as appropriate. Results: A total of 29 patients underwent laparoscopic RP using 3D display system and 66 patients underwent laparoscopic RP using 2D display system. The two groups were comparable for all clinical and pathological variables. Mean total operative time for the 3D group was 131 min (standard deviation (SD) ±18) compared to 190 (SD ±31) for the 2D group (p<0.001). Mean time to perform the urethro-vesical anastomosis was 28 min (SD ±6) for the 3D group compared to 87 (SD ±17) for the 2D group (p<0.001). Blood loss was lower in the 3D group and the difference was statistically significant (p<0.001). A statistically significant higher number of patients in the 3D group had early recovery of continence compared to patients in the 2D group (14/28 (50%) patients in the 3D group vs. 16/64 (25%) patients in the 2D group, p=0.02). Conclusions: Laparoscopic RP aided by a new-generation 3D display system is associated with shorter operative times, reduced blood loss and higher early continence rates in comparison to that aided by a 2D display system. In particular when considering economic issues, 3D laparoscopic RP may represent an acceptable alternative to robot-assisted laparoscopic RP.
