Possible predictor of early recovery on urinary continence after laparoscopic radical prostatectomy - Bladder neck level and urodynamic parameters

To investigate the relationship between post-operative bladder neck levels and urodynamic parameters and their effect on urinary incontinence after laparoscopic radical prostatectomy (LRP).

Forty-eight consecutive patients undergoing LRP were retrospectively reviewed. All patients were assessed using retrograde cystography after LRP and were grouped according to their bladder neck position: Level 0: at or above the superior margin of the symphysis pubis (SMSP); Level -1: at <2 cm below SMSP; and Level -2: at >2 cm below SMSP. Urodynamic studies were conducted at baseline as well as at 1 and 3 months post-operatively. Early recovery of urinary continence was defined as no urine leakage or only one pad/day used within 3 months after surgery. Demographic characteristics, changes in urodynamic parameters, and continence outcomes were analyzed.

Overall rate of early recovery of urinary continence was 33.3%. Patients with higher bladder neck levels experienced a significantly earlier recovery of urinary continence in univariate analysis (77.8%, 29.2%, and 13.3% for bladder neck levels 0, -1, and -2, respectively, p = 0.004). Patients with early recovery of urinary continence had significantly longer functional profile lengths (FPLs) 1 month post-surgery (21.0 mm vs 14.8 mm, p = 0.019). Higher bladder neck levels were significantly associated with longer FPLs at 1 month (p = 0.032).

Bladder neck level is associated with FPLs at 1 month post-surgery, which is the possible predictor of early recovery of urinary continence after LRP. Patients with longer FPL at 1 month after LRP have a higher rate of early recovery of urine continence.
