The problem of early continence recovery after radical prostatectomy

Background. The highest rate of incontinence after radical prostatectomy (RP) is observed in the first 2–6 months after surgery. In order  to decrease the period of incontinence, virous surgical methods aimed at preservation and reconstruction of structures participating  in the mechanism of urine retention has been developed and improved.

The study objective is to evaluate effectiveness of an original method of formation of an urethral anastomosis in the early continence recovery.

Materials and methods. Data on 126 patients who underwent retropubic RP were analyzed. Depending on the method of urethral anastomosis formation, patients were divided into 2 groups: in the 1^st group (n = 52) the patients underwent PR with urethra suspension m. levator ani, in the 2^nd (n = 74) – standard RP. In the 1^st group, 6 ligatures were applied to the anterior and posterior urethra walls: at the 12 and 6 hour projections through the mucosa, submucosa, and smooth muscle; at the 10, 2, 4, and 8 hour projections – more laterally with capture of the m. levator ani medial margins. Continence recovery was evaluated on days 1, 7, and 14 after urinary catheter removal and then at days 30, 90, 180, and 365 after RP. The criteria of continence were absence of urine leakage at rest and during physical activity and a necessity of using a safety liner.

Results. There weren’t any significant differences at day 1 after urinary catheter removal between the two groups (р > 0.05). In the 1^st group, continence values at days 30, 90, and 180 after RP were significantly higher (57.7, 69.2, and 71.1 %, respectively) compared to the 2^nd group (35.1, 41.9, and 51.3 %, respectively) (р <0.05).
