Effect of vesicourethral anastomosis technique on functional results in retropubic radical prostatectomy.

AIM: We aimed to compare the functional results of two different vesicourethral anastomosis (VUA) techniques used in open retropubic radical prostatectomy.

METHODS

A total of 476 patients including the first group with four-focus VUA at 12-, 3-, 6-, and 9-o'clock positions (n = 288) and the second group with six-focus VUA at 12-, 2-, 4-, 6-, 8-, and 10-o'clock (n = 188) were included in the study. Perioperative data, erectile function, and continence status over a 12-month period were compared.

RESULTS

Demographic and perioperative data were similar between two groups. The number of patients with VUA stricture in the first group was significantly higher those in the second group (5.1% vs 3.2%, P = .017). The mean time to stricture development was also shorter in the first group (48.9 vs 74.3 days, P = .002). The number of continent patients at the 6th and 12th months were higher in the second group (79.3% vs 62.8%, P < .001; 92.4% vs 81.3%, P = .032, respectively). There was no significant difference between two groups in terms of the number of potent patients (P = .194 for 6 months and P = .351 for 12 months).

CONCLUSIONS

Better continence results can be provided with the six-focus VUA technique compared with the four-focus technique. The number of anastomotic sutures in VUA may affect functional results and can be a determinative factor for surgeons who focus on functional results as well as oncological results.
