Urodynamic examinations were performed in 82 patients with clinically localized prostate cancer before and after radical prostatectomy. A significant decrease in bladder capacity (396 ml to 331.9 ml), urethral closure pressure (89.6 cm H2O to 65.2 cm H2O) and functional profile length (61 mm to 25.9 mm) was noted. The continence rate after radical prostatectomy was 33.4% after 1 month, 69.4% after 3 months, 84.7% after 6 months, and 90.9% after 12 months, respectively. A correlation was found between urethral closure pressure and functional profile length and continence. A second urodynamic examination was performed 6 months after radical prostatectomy. Functional profile length and urethral closure pressure increased. These data suggest that restoration of continence is based on sphincteric parameters.
对82例临床局限性前列腺癌患者在根治性前列腺切除术前和术后进行了尿动力学检查。结果发现膀胱容量（从396毫升降至331.9毫升）、尿道闭合压（从89.6厘米水柱降至65.2厘米水柱）和功能尿道长度（从61毫米降至25.9毫米）显著下降。根治性前列腺切除术后1个月、3个月、6个月和12个月的控尿率分别为33.4%、69.4%、84.7%和90.9%。发现尿道闭合压和功能尿道长度与控尿之间存在相关性。在根治性前列腺切除术后6个月进行了第二次尿动力学检查。功能尿道长度和尿道闭合压增加。这些数据表明控尿的恢复基于括约肌参数。
