The Impact of Lateral Bladder Neck Preservation on Urinary Continence Recovery After Robot-Assisted Radical Prostatectomy.
Journal of Endourology 2018 January
OBJECTIVE: Urinary incontinence is one of the most bothersome adversities after robot-assisted radical prostatectomy (RARP). The aim of this study was to investigate the urinary continence recovery and the effect of various surgical techniques.
MATERIALS AND METHODS: We previously reported that posterior rhabdosphincter reconstruction and nerve-sparing were independent predictors of urinary continence recovery 1 month after catheter removal in 199 patients who underwent RARP. Retrospectively, we further reviewed those 199 patients for urinary continence recovery at 3 months or later after RARP. The relationships of urinary continence with perioperative findings, including surgical procedures, were evaluated at 3 to 12 months after RARP. The Fisher exact test and Mann-Whitney rank sum test were used for evaluating variables between the groups. Multivariate logistic regression analysis was performed to investigate the association between urinary continence and perioperative factors.
RESULTS: On univariate analyses, surgeon experience, lateral bladder neck preservation (BNP), anterior reconstruction, and posterior reconstruction were significantly associated with urinary continence recovery 3 months after RARP, but only lateral BNP was independently associated with urinary continence recovery in a multivariate analysis. Similarly, on univariate analyses, surgeon experience, lateral BNP, and posterior reconstruction were significantly associated with continence recovery at 6 months or later after surgery. However, multivariate analyses showed that only lateral BNP was significantly associated with urinary continence recovery 6 months or later after surgery.
CONCLUSION: Although the lateral BNP technique did not affect immediate urinary continence recovery, this procedure was significantly associated with continence recovery 3 months or later after RARP.
