  •   Objective  To compare the efficacy and safety of three-dimensional (3D) and two-dimensional (2D) imaging systems in laparoscopic extraperitoneal radical prostatectomy (LERP) for prostate cancer.  Methods  The clinical data of 122 consecutive patients diagnosed with prostate cancer was analyzed. Those patients were underwent LERP with 2D or 3D imaging systems in Nanfang Hospital and Guangdong General Hospital between January 1st, 2015 to 1 January 1st, 2018. Patients were divided into 3D (n=40) and 2D (n=82) groups according to different endoscopic methods. The patients in 2D group and 3D group were matched by propensity score matching method according to age, BMI, prostate volume, preoperative total prostate specific antigen (PSA) and Gleason score of prostate puncture pathology. After matching, 40 cases were included in each group. The matched patients were further followed up with urinary incontinence quality of life scale (I-QOL) and international index of erectile function-5 (IIEF-5). The effects of the two surgical methods were analyzed, and the safety was compared and analyzed.  Results  The operation time of 3D group was shorter than that of 2D group [2.3 (2.0, 3.0) h vs. 3.0 (2.3, 4.0) h, P=0.023], and the blood loss of 3D group was less [50.0 (50.0, 137.5) mL vs. 275.0 (112.5, 337.5) mL, P < 0.001]. There were no statistically significant differences in positive surgical margin rates, urinary leakage rate, recovery rate of urinary control, recovery of sexual function and biochemical recurrence rate between the two groups (all P>0.05).  Conclusion  3D LERP has a better surgical field, shorter operation time, and less blood loss compared to 2D LERP. However, the long-term follow-up results of the two groups were similar in the positive surgical margin rates, the recovery rate of urinary control, the recovery of sexual function and biochemical recurrence rate.
