    Figure 1.

    Figure shows the apical dissection of porstate at Retzius-sparing LRP. In the opening of peritoneal at Cau-de-sac, bilateral neurovascular bundle preservation and interfascia dissection was performed.Prostate was pull downward at seminal vesical by assistant to exposed the prostate apex.

    The ratio would be calculated by measuring the distance from the superior edge of the pubic symphysis to the bladder neck and dividing by the total pubic symphysis height; this so-called bladder neck to pubic symphysis (BNPS) ratio.

    Figure 3.

    A Kaplan survival curve was used to evaluate the continence ratios among the two groups, and the continence rates at 1 week, 1 month, 3 months, 6 months, and 12 months were 26.7%, 30.0%, 56.7%, 76.7%, and 93.3%, respectively, compared with 73.3%, 91.0%, 94.2%, 97.7%, and 100%, respectively. The p-value of log-rank test among the two groups was 0.000.

    Figure 4.

    A 68-year-old male patient with pathology T3 prostate cancer, measure about 40 gm, PSA 9.63 ng/ml, received a retropubic approach RARP. The operation time was 175 min, and the EBL was 100 ml. The BNPS ratio was 0.43, and the patient achieved continence at the sixth month after Foley removal.

    A 58-year-old male patient with pathology T2 prostate cancer, measure about 60 gm, PSA 5.04 ng/ml, received a Retzius-sparing RARP. The operation time was 168 min, and the EBL was 80 ml. The BNPS ratio was 0.22, and the patient achieved immediate continence one week after Foley removal.
