目的:评价膀胱内前列腺突入(intravesical prostatic protrusion,IPP)预测腹腔镜前列腺癌根治术(laparoscopic radical prostatectomy,LRP)后早期尿控恢复的临床价值。方法:选择242例接受LRP患者,评估其术后1、3、6、12个月的尿控情况,探讨术后尿失禁和术前因素之间的关系,并根据IPP程度分为显著IPP组(IPP≥5 mm,n=55)和非显著IPP组(IPP<5 mm,n=187),分析IPP程度与尿控关系。结果:242例患者术后1、3、6、12个月的尿控率分别为19%、50%、79.8%和92.1%;经单因素和多因素Logistic回归分析,IPP是术后1、3、6、12个月早期尿控的显著独立预测因素;非显著IPP组尿控改善明显优于显著IPP组(P<0.05)。结论:膀胱前列腺突入程度与患者腹腔镜前列腺癌根治术后尿控密切相关,可作为患者早期尿控恢复的重要预测指标。
Objective: To evaluate the clinical value of intravesical prostatic protrusion (IPP) in predicting early urinary control after laparoscopic radical prostatectomy (LRP). Methods: 242 patients with LRP were enrolled in this study to evaluate their urinary control status at 1, 3, 6 and 12 months after operation. The relationship between postoperative urinary incontinence and preoperative factors was analyzed. According to the degree of IPP, the patients were divided into significant IPP group (IPP≥5 mm, n = 55) and non-significant IPP group (IPP <5 mm, n = 187). Results: The urinary control rates of the 242 patients at 1, 3, 6 and 12 months after operation were 19%, 50%, 79.8% and 92.1% respectively. According to the univariate and multivariate logistic regression analysis, Significant independent predictors of early urinary control were observed at 3, 6, and 12 months; improvement in urinary control was significantly better in non-significant IPP group than in significant IPP group (P <0.05). Conclusions: The degree of bladder prostatic involvement is closely related to the postoperative urinary control of laparoscopic radical prostatectomy, which can be used as an important predictor of early urinary control in patients.
