Abstract

To examine which preoperative factors, including urodynamic evaluations, and operative procedures could predict continence status after robot-assisted radical prostatectomy (RARP) in this study. Univariate and multivariate logistic regression analyses of preoperative factors such as age, body mass index, prostate-specific antigen level before biopsy, prostate size before surgery, membranous urethral length measured using magnetic resonance imaging (MRI), bladder compliance and maximum urethral closure pressure (MUCP) measured by urodynamic study (UDS), and nerve-sparing (NS) status predicting 24-hr pad test >2 g/day at 1 year after RARP were examined in 111 patients enrolled in this study. The number of patients with incontinence at 1 year after RARP was 39 (35.1%). The only predictive factor for urinary continence was NS grades. To investigate the contribution of NS to urinary continence, 84 patients underwent UDS three times; before, immediately after, and 1 year after RARP. Chronological UDS revealed that recovery patterns of storage and voiding functions were the same among non-NS, unilateral-NS, and bilateral-NS groups, and that higher degrees of NS contributed to lesser decreases in MUCP and longer functional urethral len...Continue Reading
