概要:

Aims: To examine which preoperative factors, including urodynamic evaluations, and operative procedures could predict continence status after robot-assisted radical prostatectomy (RARP) in this study. Materials and Methods: 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. Results: 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 length (FUL) after RARP. Conclusion: Preoperative factors, including the results of UDS, could not predict continence 1 year after RARP. The NS procedure contributed to continence status. NS favorably affected MUCP and FUL; however, it did not affect bladder function after RARP. Neurourol.
