- Abstract: PURPOSE: To report our results on urinary continence after bladder neck preservation (BNP) and posterior urethral reconstruction (PUR) during robot-assisted laparoscopic radical prostatectomy (RALP). MATERIALS AND METHODS: Data from 107 patients who underwent RALP were compared on the basis of whether the patients underwent BNP and PUR, BNP only, or the standard technique (ST). In group A (n=31 patients), ST was performed by using Ven velthoven continuous suturing for urethrovesical anastomosis. In group B (n=28 patients), ST with only PUR was performed. In group C (n=48 patients), both the BNP and PUR techniques were used. "Recovery of continence" was defined as the use of 1 pad (50 ml) or less within 24 hours. RESULTS: The three groups were comparable in terms of patient demographics. The mean operative time and the mean blood loss decreased significantly from group A to group C (p=0.021 for mean operative time and p=0.004 for the mean blood loss). Mean catheterization time was 8.9, 7.8, and 7.1 days in each group (p=0.047). Early return of urinary continence at 3 months was observed in group B (89.2%) and group C (90.6%) compared with group A (71%). However, continence at 6 months was comparable in the 3 groups (87.5% in group A, 92.8% in group B, and 92.3% in group C). Rates of positive surgical margins decreased from 30.2% in group A to 20% in group B and 12% in group C. CONCLUSIONS: BNP and PUR during RALP showed a favorable impact on the early postoperative recovery of continence while not affecting positive surgical margins.
